Note: Before You Read Further
Blocking your PESEL number is not the same as blocking your ID card. After document theft, you need both. Blocking does not block your account. ATMs, transfers, card payments, doctor visits, prescriptions, and travel work normally. It blocks taking on new obligations. Blocking does not protect your SSN in the USA. These are two independent systems in two countries. Unblocking is not automatic. The law does not provide for automatic unblocking. If you unblock temporarily, no one will restore it for you. Set a temporary unblock. This text is for informational purposes and is not legal advice. Legal status: October 23, 2026.
Blocking your PESEL number is a free entry in the national register that prevents the conclusion of loans, credit agreements, leasing contracts, opening bank accounts, selling real estate at a notary, and issuing a duplicate SIM card in your name. Financial institutions are required to check this register starting June 1, 2024.
Blocking does not invalidate your ID card, does not block ATMs, transfers, doctor visits, or crossing borders. It also does not work outside of Poland, so it does not protect your American SSN in any way.
Below: what the regulations say, how to block PESEL through three channels, how to do it from abroad, and when you need to temporarily unblock.
What is a PESEL Number
PESEL is an eleven-digit number assigned to individuals registered in the PESEL register. The rules for its assignment are specified in the Act of September 24, 2010, on population registration.
PESEL is not a secret. It appears on many documents and in some public registers. Therefore, the legislator created a protective mechanism that relies not on hiding the number but on blocking it.
Only Poland: PESEL is also held by many Poles living permanently in the USA, Canada, or the UK, assigned at birth or later, upon request submitted at the Polish consulate. The risk of fraud using your data in Poland exists regardless of where you live.
What is Blocking a PESEL Number
Blocking is the entry of information about the blocking of your number in the PESEL number blocking register, which is a national register maintained by the minister responsible for digitization (Article 23d, paragraph 1 of the Act on population registration).
The register was established under Chapter 3a of this Act (Articles 23a–23p), added by the Act of July 7, 2023, on amending certain acts to limit some effects of identity theft (Dz.U. 2023, item 1394). Its purpose is, literally according to Article 23a, paragraph 1, "to prevent negative consequences of unauthorized use of personal data of individuals who block their PESEL number."
The register collects very little data: PESEL number, information about the blocking and unblocking, the moment of each of these actions, and the designation of the entity that registered it (Article 23c, paragraph 1). It does not contain your address, income, or credit history. Data is not deleted (Article 23c, paragraph 3), and only data of adults is collected (Article 23a, paragraph 2).
Four Different Things That People Confuse
1. Blocking a PESEL number: a state register, free of charge, maintained by the Ministry of Digitization. It blocks actions specified in the law. It concerns the number, not the document.
2. Reporting the loss of an ID card: a procedure under the Act of August 6, 2010, on ID cards. It invalidates the ID immediately, even at night and on holidays. Side effect: for an adult, reporting the loss of an ID results in the PESEL number being blocked automatically (Article 23g, paragraph 1, point 1 of the Act on population registration).
3. The DOKUMENTY ZASTRZEŻONE system is not a state register. It is maintained by the Polish Bank Association, has been operating since 1997, and sends information about lost documents to banks, mobile operators, and thousands of companies. Reports are accepted by banks, according to information from the ZBP, even from individuals who do not have an account there.
4. BIK Alerts are a paid commercial service of the Credit Information Bureau S.A. It notifies you of inquiries about your credit history but does not block anything. You can obtain a free copy of your data from BIK based on Article 15 of the GDPR; this is not the same as the paid BIK Report.
The fifth thing is blocking a document at a bank, which is an internal action of one bank.
Who Can Block and How Much Does It Cost
According to Article 23e, paragraph 1, blocking and unblocking can be done by an adult whose data is in the PESEL register, and it is free of charge. The service page on gov.pl confirms: "The service is free" and "The service will be executed immediately."
The law provides for two own channels (Article 23e, paragraph 2): electronically, in a service provided by the minister, after authentication in the manner specified in Article 20a, paragraph 1 of the Act on digitization or with a certificate from a public mobile application; or in writing, in person at the office of any municipality, on paper, with a handwritten signature.
The third channel is optional for institutions. Article 23f allows a domestic bank, SKOK, and the designated operator (Polish Post) to enable blocking at the branch or in electronic banking. The word "may" is significant: they are not obligated. And there is a limitation: Article 23f applies only to blocking. You cannot unblock at the bank or post office.
For a person without legal capacity or with limited capacity, the application is submitted by a legal guardian or curator at the municipality office (Article 23e, paragraph 5). A proxy is only allowed in exceptional cases (Article 23e, paragraph 4): when submitting the application is impossible "due to illness, disability, or another insurmountable obstacle." According to the service description on gov.pl, a proxy can only block, not unblock.
How to Block PESEL in the mObywatel App
The service is called Block PESEL. It is a separate item from "Block Document," so do not confuse them.
- Open the mObywatel app and log in.
- Go to the list of services and select Block PESEL.
- Press Block PESEL and confirm. It works immediately.
On the same screen, you have two useful buttons: Who Checked Your PESEL and Your Changes (history of blocks and unblocks).
The official app page confirms: "Both blocking the PESEL number and unblocking it are immediate and occur in real time, even at night and on holidays."
How to Block PESEL via gov.pl
- Go to gov.pl/web/gov/block-your-pesel-number-or-unblock-it.
- Click Block PESEL or Unblock.
- Log in. The page lists four methods: trusted profile, qualified signature, e-ID, login data for electronic banking.
- The system will transfer you to the mobywatel.gov.pl service.
- Select Block PESEL or Unblock.
Free of charge and immediate. Conditions: you have a PESEL number and are an adult. To block your own number, you do not need to provide the series of your ID or passport; logging in is sufficient.
How to Block PESEL at the Municipality Office
You submit the application in person at any municipality office, it does not have to be the municipality of residence. Free of charge and immediate. Bring your ID card (it can be a document in the mObywatel app) or passport; a foreigner brings a travel document or another document confirming identity and citizenship.
You can fill out the application in advance (the template is specified in the regulation of the Minister of Digitization of November 7, 2023, Dz.U. 2023, item 2485) or ask the official for a printout from the system. The official verifies your identity and compares your data and image with the ID Card Register (Article 23i, paragraphs 1 and 3), and then "immediately after submitting the application and positive verification of identity" registers the block and issues a confirmation (Article 23i, paragraph 4).
How to Block PESEL While Living Abroad
The law does not provide for blocking PESEL at the consulate. Article 23e, paragraph 2 only mentions the electronic service and the office of any municipality. In comparison, for the ID card, the legislator explicitly mentions the consulate (Article 47, paragraph 1 of the Act on ID cards). Official gov.pl pages about blocking PESEL consistently say "at any municipality office."
Realistically, you have one way without coming to Poland: log in to the electronic service: with a trusted profile, qualified signature, e-ID, or data for Polish electronic banking.
How to Obtain a Trusted Profile from Abroad
The official FAQ of the Trusted Profile service answers the question "Can I create a trusted profile without leaving home?" with "Yes" and lists four methods:
- bank or another identity provider, with the caveat: "The list of banks that allow you to create a trusted profile is limited";
- e-ID: an ID with an electronic layer plus an NFC reader or a smartphone with an NFC antenna;
- video call with an official: requires a valid Polish ID or a valid Polish passport, with the passport being used "if you have ever had an ID card issued after December 31, 2000"; the call takes place via Microsoft Teams, at a time according to Polish time;
- qualified certificate: with an NFC reader and the Podpis GOV application.
There is also a mixed route: an online application and confirmation at a confirmation point. The FAQ states directly: "You can confirm your trusted profile at any confirmation point, including abroad."
The Polish consulate confirms the trusted profile. The consular page gov.pl/web/usa states: "You can confirm your trusted profile on the ePUAP platform at any chosen consular office." Submit an online application, then appear in person at the consulate within 30 days, with a valid identity document. You schedule the visit through e-consulate, free of charge.
Note from the same page: the data in the application must be in Polish spelling. "Malgorzata" instead of "Małgorzata" will not pass verification with the PESEL register.
Three Traps Typical for the Polish Diaspora
Foreign phone number. SMS codes may not be delivered to foreign numbers. The Trusted Profile FAQ directs you to the helpline +48 42 253 54 50 (weekdays, 7–18 Polish time).
No Polish ID. If you have never had a Polish ID issued after December 31, 2000, the "video call" route is closed. You are left with the consulate or a Polish bank.
A proxy is not a workaround. Living abroad is not a condition under Article 23e, paragraph 4. A proxy still has to appear at a Polish municipality office and can only block.
A Roundabout Way That Works
If your ID is lost or stolen, you can report the loss at the consulate (Article 47, paragraph 1 of the Act on ID cards; paragraph 3 allows for a letter by mail or fax), and such a report by an adult automatically blocks the PESEL from the office. This is not a way to block preventively, but in a real situation of document loss, it works from abroad.
Automatic Blocking, or When It Happens Automatically
Article 23g, paragraph 1 lists two cases without your application: invalidating the ID card due to reporting its loss (Article 47 of the Act on ID cards) or reporting suspicion of unauthorized use of personal data (Article 48a of this Act), and registering death data (Article 8, point 26).
The first point contains an underrated possibility: Article 48a allows you to invalidate your own ID on mere suspicion that someone unauthorized is using your data, without losing or damaging the document. The report is made in person at the office of any municipality. Note: under Article 48a, the law does not mention the consulate, unlike under Article 47.
There is no automatic unblocking. A new ID does not remove the block. You must unblock it yourself.
How to Check the Status and Who Checked Your PESEL
Insight into your own data (Article 23k, paragraph 1): in the mObywatel app or by logging in to mobywatel.gov.pl. The Ministry of Digitization defines this as "the right to free and permanent online access."
Insight into who and when verified the block (Article 23l, paragraph 1): the button Who Checked Your PESEL. Note the scope: in verifications by a regular user of the service under Article 23j, the information shows the entity only if the verifier acted on behalf of another entity (Article 23l, paragraph 5). The time scope is limited to the log retention period, which is 6 years.
Certificate from the register (Article 23k, paragraphs 2 and 5): online free, at the office 17 PLN of stamp duty. A certificate ordered online goes exclusively to the e-Delivery inbox. Such a file should not be printed: the official document is only in electronic form, as it bears an electronic seal that cannot be verified on a printout.
Separately: anyone can check someone else's PESEL number (Article 23j, paragraph 1), free of charge, after logging in, by providing the PESEL number and the series and number of that person's last ID or passport. Anyone acting on behalf of a company must indicate it under penalty of criminal liability (Article 23j, paragraphs 5 and 6).
How to Unblock and What Temporary Unblocking Is
Unblocking is done in the same two ways as blocking: electronically or in person at any municipality office (Article 23e, paragraph 2). You cannot do it at the bank or post office.
Temporary unblocking exists and is in the law. Article 23d, paragraph 3: "Unblocking the PESEL number in the manner referred to in Article 23e, paragraph 2, point 1, can also be done temporarily, indicating the moment of re-blocking the PESEL number." Referring to "Article 23e, paragraph 2, point 1" means that temporary unblocking is available only in the electronic channel. Gov.pl confirms: "you can do this: indefinitely or specify the date and time when the system will automatically re-block your PESEL number."
30-Minute Block. Article 23d, paragraph 5: "You cannot report the blocking of the PESEL number for 30 minutes from the moment the unblocking was done." After unblocking, you are exposed for at least half an hour, even if you change your mind after a minute. Therefore, temporary unblocking is better: you do not have to remember to return.
Change of PESEL Number. Article 23d, paragraph 6: if your number was changed under Article 19, the blocking of the old does not cover the new one.

Cash Withdrawal: The Only Case with a Monetary Threshold
Article 105d, paragraph 2 of the Banking Law: the bank checks the register before cash withdrawal at a branch, made by an account holder who is a consumer, when that withdrawal (either singly or as a subsequent one) causes the total cash withdrawals on that day at all branches of that bank to exceed three times the minimum wage. In 2026, the minimum wage is 4806 PLN (Dz.U. 2025, item 1242), so the threshold is 14,418 PLN.
If the PESEL is blocked, the bank "suspends the cash withdrawal for 12 hours from the moment the request is made, despite unblocking during that time." Unblocking after the request does not shorten those 12 hours. When planning a large cash withdrawal at the counter, unblock before you enter the branch. The same mechanism applies in SKOKs (Article 36, paragraph 2a of the SKOK Act). The ATM is not covered by this provision, as it only refers to withdrawal "at the branch."
When to Temporarily Unblock
Unblock the block (preferably temporarily, with a set return time) before:
- you apply for a loan, credit, or leasing;
- you open a new savings or savings and checking account;
- you sign an addendum increasing debt;
- you buy something on installments if it is consumer credit;
- you go to a notary for an act concerning real estate or for a power of attorney for such an action;
- you exchange your SIM card for a duplicate or transfer your number to eSIM;
- you withdraw at a bank counter above 14,418 PLN (as of 2026).
You do not need to unblock for: ATM, transfer, card payment, doctor, prescription, travel, registration, marriage, employment contract, elections, lease agreement, and car purchase. Set the re-blocking for a few hours after the planned action, not for a few days.
Who is Obligated to Check the Register
Article 23m, paragraph 1 lists entities to which the minister provides data from the register through verification: banks and institutions established under Article 105, paragraph 4 of the Banking Law, notaries, providers of publicly available telecommunications services, SKOKs, lenders as defined by the Consumer Credit Act, designated payment service providers, economic information bureaus, and starting November 27, 2025, also insurance companies and the Insurance Guarantee Fund (Dz.U. 2025, item 1176).
However, the obligation to check and the consequences of its violation arise from industry laws. Their numbers can be found in the "Basis" column in the table above. All of them came into force on June 1, 2024.
Failures are regulated separately: when the system is unavailable, the bank and lender may either refuse to conclude the contract after a subsequent failed attempt or conclude it with due diligence in verifying identity. The notary may withhold or perform the action.
Legal Consequences of Blocking
The strongest provision is Article 105d, paragraph 3 of the Banking Law. A domestic bank, credit institution, branch of a credit institution, and branch of a foreign bank "cannot demand from the consumer and their legal successors satisfaction of a claim arising from the conclusion of the contract specified in paragraph 1 nor transfer the receivable arising from this contract, if at the time of concluding the contract (...) the PESEL number of that consumer was blocked." Twin provisions: Article 9b, paragraph 2 of the Consumer Credit Act and Article 4b, paragraph 2 of the Payment Services Act.
Three blocks that are rarely mentioned:
- Article 105d, paragraph 3 applies to contracts from paragraph 1, does not cover cash withdrawals from paragraph 2.
- Article 105d, paragraph 6 excludes paragraph 3 if the contract was concluded during system unavailability lasting longer than 15 minutes, other than planned and announced failure.
- The law speaks of a ban on pursuing a claim. This does not mean that the creditor will cease actions on their own. In practice, it may be necessary to invoke this provision, and in case of dispute, the judicial route. This is not a promise that the money will be returned.
There is also a consequence concerning credit history. Article 105, paragraph 4j of the Banking Law: if at the time of concluding the contract the PESEL was blocked, the obligation to transmit information about newly created obligations does not apply, and paragraph 4k requires this to be checked before transmitting information.
Legal ambiguity that we signal as unclear: the law does not specify the procedure for removing an entry from credit registers that has already arisen despite these provisions, nor the deadline for the creditor to withdraw from the contract. It provides a material basis but not a procedure. Individual legal advice is needed in such cases.
What to Do Immediately
- Block your PESEL number in mObywatel or on gov.pl. It works immediately.
- Report the loss of your ID card: gov.pl, municipality office, or abroad at the Polish consulate.
- Report the document at the bank to get it into the DOKUMENTY ZASTRZEŻONE system.
- Report the theft to the police if it was theft.
- Contact your mobile operator and secure your number against issuing a duplicate SIM.
- Change passwords for banking, email, and social media; enable two-factor authentication.
- Order a free copy of your data from BIK and check for any obligations you did not incur.
What to Do After Document Leakage
You sent a scan or photo of your ID to a scammer. You have the document, but a copy is circulating. Block your PESEL and consider using Article 48a of the Act on ID cards, which allows you to report at any municipality office the suspicion of unauthorized use of data, which invalidates the ID and triggers the PESEL blocking from the office. Report the incident to CERT Polska.
Your data leaked from a company or office. Block your PESEL, order a copy of your data from BIK, monitor your account. You can file a complaint with the UODO, but the UODO emphasizes that you must first make a request directly to the data administrator. The form for reporting a breach on the UODO website is intended for administrators, not for victims.
You lost the document or it was stolen. Follow the full procedure from the "What to Do Immediately" list.
In all three cases, keep the blocking enabled permanently.
Suspecting Credit in Your Name
- Block your PESEL if you haven't done so already.
- Check if the obligation exists: order a free copy of your data from BIK (Article 15 of the GDPR) and check economic information bureaus.
- Check who verified your block. Verification by an institution with which you have no connection is a warning sign.
- File a notification of suspected crime with the police or prosecutor's office.
- Write a complaint to the institution that granted the obligation. If the PESEL was blocked at that time, invoke Article 105d, paragraph 3 of the Banking Law or Article 9b, paragraph 2 of the Consumer Credit Act.
- If the complaint does not help, the Financial Ombudsman conducts proceedings in disputes with financial market entities.
Most Common Misunderstandings
- "Blocked PESEL means a blocked account." No. It blocks the establishment of new products, not the use of existing ones.
- "Blocking invalidates the ID." No. The dependency works one way: reporting the loss of an ID blocks the PESEL, not the other way around.
- "I blocked my PESEL, so I don't need to block my ID." No. DOKUMENTY ZASTRZEŻONE is a different database and reaches entities outside the financial sector.
- "BIK Alerts are the same, just more convenient." No. Alerts do not block anything, they inform after the fact.
- "The bank will definitely return my money." No. The regulations prohibit pursuing claims from such a contract. This is not the same as a guarantee of return, and there is an exception to the prohibition in case of system failure.
- "The consulate will block my PESEL." The law does not provide for this. The consulate will confirm the trusted profile, which you will use to block the PESEL yourself.
Myths and Facts
| Myth | Fact |
|---|---|
| Blocking costs | "Free of charge" (Article 23e, paragraph 1) |
| You have to go to your municipality | The application is submitted at the office of any municipality |
| Blocking has an expiration date | It does not. It lasts until you unblock it |
| After obtaining a new ID, the block disappears | It does not disappear. The law does not know of unblocking from the office |
| Unblocking is always indefinite | It can be temporary, but only electronically (Article 23d, paragraph 3) |
| After unblocking, you can immediately block again | No. 30-minute block (Article 23d, paragraph 5) |
| Changing the PESEL number transfers the block | No transfer (Article 23d, paragraph 6) |
| Blocking protects me in the USA too | No. It has no effect on the SSN |
Most Common Mistakes
- Unblocking indefinitely "for a moment" and forgetting. The most common mistake. Use temporary unblocking.
- Unblocking only at the branch for a large withdrawal. The bank will still suspend the withdrawal for 12 hours.
- Blocking PESEL instead of reporting the loss of the ID. After theft, both actions are needed.
- Relying solely on paid alerts. Alerts inform, blocking prevents.
- Assuming that blocking protects a lease agreement or car sale. It does not protect.
- Data in non-Polish spelling when applying for a trusted profile. Verification will fail.
- Printing a certificate from the register. A printout is not an official document.
- Delaying. Blocking after the fact does not invalidate a contract concluded earlier, as the regulations refer to the state "at the time of concluding the contract."
Where to Report Fraud or Incident
Only Poland:
- Police / prosecutor's office: notification of suspected crime. The first step in case of credit fraud in your name.
- CERT Polska (CSIRT NASK): phishing, fake SMS, malicious sites: form at incydent.cert.pl or email cert@cert.pl. A suspicious SMS can be forwarded to the number 8080 (free in Poland; outside the country, costs according to the operator's tariff; up to 3 messages in 4 hours from one number).
- Your bank: complaint and blocking.
- Financial Ombudsman: when the complaint at the financial institution was ineffective.
- UODO: complaint when your data processing violates the GDPR. First, you must make a request to the administrator; the complaint is directed to the address for electronic deliveries of the UODO, not by email.
Only USA: What PESEL Blocks and What It Does Not Apply To
A sentence to remember: blocking the PESEL number does not protect against misuse of the Social Security number.
These are two independent systems in two jurisdictions. The Polish register binds Polish banks, notaries, and operators. An American bank, credit card issuer, or the IRS does not check the Polish register because they do not have access to it or an obligation. If you have both numbers, you need two separate protections.
Only Poland: block PESEL. It protects against loans, accounts, notarial acts, and duplicate SIMs in Poland.
Only USA: the functional equivalent is a credit freeze (security freeze) at the three credit bureaus: Equifax, Experian, and TransUnion. It is free under federal law and must be established separately at each bureau; the rules and references are described by the FTC at consumer.ftc.gov. Further:
- IdentityTheft.gov: a government tool from the FTC: you report identity theft and receive a recovery plan and Identity Theft Report.
- AnnualCreditReport.com: the only official service for free credit reports from the three bureaus.
- IRS Identity Protection PIN: a PIN without which no one can file a tax return on your SSN.
- Social Security Administration: my Social Security account allows you to monitor records related to the number.
Order: freeze at the three bureaus → report at IdentityTheft.gov → police report → complaints to creditors.
What Applies from June 1, 2024, and What Changed Later
November 17, 2023 – the register of PESEL blocks was launched. The date was set by the announcement of the Minister of Digitization on October 31, 2023 (M.P. 2023, item 1194), issued under Article 21, paragraph 1, points 1 and 3 of the Act of July 7, 2023. The same announcement activated Article 23f. On that day, the regulation with application templates also came into force (Dz.U. 2023, item 2485).
December 27, 2023, and January 10, 2024 – authentication with a certificate from a public mobile application: the day of implementation and the day of general availability of services (announcement of the Minister of Development and Technology from December 7, 2023, M.P. 2023, item 1371).
June 1, 2024 is the most important date. The verification obligations on the part of institutions came into force: Article 85, § 2a and Article 85a of the Notarial Law, Article 105, paragraphs 4j, 4k, and Article 105d of the Banking Law, Article 60c of the then Telecommunications Law, changes in the SKOK and economic information laws, Article 9b of the Consumer Credit Act, Article 4b of the Payment Services Act (Article 26, point 9 of the Act of July 7, 2023). Previously, you could block the number, but no one had to check it.
November 10, 2024 – the Telecommunications Law lost its validity; the operator's obligation was transferred unchanged to Article 297 of the Electronic Communications Law (Dz.U. 2024, item 1221).
November 27, 2025 – insurance companies and the UFG were added to Article 23m, paragraph 1 (Dz.U. 2025, item 1176).
April 27, 2026 – changes concerning foreigners without a travel document: new Article 23i, paragraph 1a and amended Article 23j, paragraph 2, point 2, letter b (Dz.U. 2025, item 1794; announcement M.P. 2026, item 370). The mechanics of blocking for Polish citizens remain unchanged.
January 11, 2027 amendments from the Act of July 31, 2026, on amending the Banking Law (Dz.U. 2026, item 1206) will come into force: in Article 105d of the Banking Law, "branch of a foreign bank" will be replaced with the term "branch from a third country," and Article 23m, paragraph 1, point 3 of the Act on population registration was adjusted to this change. The rules for blocking and the effects of blocking do not change.
Legal status as of October 23, 2026: the consolidated text of the Act on population registration of March 12, 2026, is in force (Dz.U. 2026, item 384). Article 105d of the Banking Law has not materially changed since June 1, 2024.
Key Principles
- Blocking is free, immediate, and indefinite: it lasts until you unblock it.
- It blocks taking on new obligations, not using existing ones.
- It does not block ATMs, transfers, cards, doctor visits, prescriptions, travel, or official matters.
- The only monetary threshold applies to cash withdrawal at a bank branch: three times the minimum wage, in 2026 it is 14,418 PLN. The effect is a 12-hour suspension.
- Temporary unblocking exists, but only in the electronic channel (Article 23d, paragraph 3).
- After unblocking, there is a 30-minute block before re-blocking.
- Reporting the loss of an ID by an adult automatically blocks the PESEL from the office. There is no unblocking from the office.
- Institutions are required to check the register starting June 1, 2024.
- Blocking PESEL has no effect on SSN and American credit bureaus.
- Blocking ≠ reporting the document at the bank ≠ BIK Alerts. These are three different things.
Checklist After Document Theft
- Blocked PESEL number (mObywatel or gov.pl), first of all
- Reported loss of ID card (gov.pl, municipality office, or abroad at the Polish consulate)
- Document reported at the bank to enter the DOKUMENTY ZASTRZEŻONE system
- Notification to the police if it was theft
- Mobile operator informed, blocking the issuance of a duplicate SIM
- Changed passwords for banking, email, and social media

- Ordered a free copy of data from BIK and checked the list of obligations
- Checked registers of economic information bureaus
- Checked "Who Checked Your PESEL" in the mObywatel app
- Submitted an application for a new ID card
- Considered reporting under Article 48a of the Act on ID cards if you suspect data misuse
- Reported to CERT Polska if phishing was involved
- Only USA: credit freeze at Equifax, Experian, and TransUnion
- Only USA: report at IdentityTheft.gov and obtain Identity Theft Report
- Only USA: application for IRS Identity Protection PIN
- Blocking left enabled; temporarily unblocked for specific actions
Frequently Asked Questions
Is blocking the PESEL number paid?
No. Article 23e, paragraph 1 of the Act on population registration speaks of "free" blocking and unblocking. The service page on gov.pl confirms: "The service is free." The only charge is for the certificate from the register received at the office: 17 PLN of stamp duty. Online, the certificate is free.
Do I need a trusted profile?
It does not have to be a trusted profile specifically. The service page lists four login methods: trusted profile, qualified signature, e-ID, and login data for electronic banking. Without any of these, you will need to visit any municipality office.
How quickly does the blocking take effect?
Immediately. The register operates in real time, even at night and on holidays. The moment of blocking is recorded with second accuracy (Article 23d, paragraph 4).
Does blocking have an expiration date?
No. It lasts until unblocked. It does not expire and does not renew.
Can I unblock for just one day?
Yes, if you do it electronically. Article 23d, paragraph 3 allows for temporary unblocking, indicating the moment of re-blocking. The law does not provide for this possibility at the municipality office.
I accidentally unblocked. Can I block again immediately?
No. Article 23d, paragraph 5 introduces a block: for 30 minutes from unblocking, you cannot report blocking.
Does blocking block my ATM?
No. Gov.pl explicitly lists ATM withdrawals among the actions you can still perform.
How much can I withdraw at the bank counter without unblocking?
The threshold is three times the minimum wage, calculated as the total cash withdrawals on that day at all branches of that bank. In 2026, it is 14,418 PLN. Above the threshold, with a blocked number, the bank suspends the withdrawal for 12 hours, and unblocking during that time does not shorten this.
Does blocking invalidate my ID card?
No. These are separate procedures. The ID, passport, and driver's license remain valid.
Can I go to the doctor, travel abroad, sign an employment contract, or get married?
Yes. Blocking does not apply to health matters, travel, employment, registration, or marriage.
Can I sell an apartment?
No, until you unblock. The notary refuses to perform actions concerning the acquisition, disposal, or encumbrance of real estate, participation in it, perpetual usufruct, or cooperative ownership right to premises if the party has a blocked number (Article 85a, § 1 of the Notarial Law). The same applies to a power of attorney for such an action.
Can I rent an apartment or buy a car?
Yes. For renting and buying a car, no provision requires checking the register.
I live in the USA. Can I block PESEL without coming to Poland?
Yes, if you have a trusted profile, qualified signature, e-ID, or access to Polish electronic banking. You can create a trusted profile remotely (bank, e-ID with NFC, video call with an official) or confirm it in person at any Polish consulate. We did not find an official source confirming that the consulate can block PESEL. The regulations only mention the electronic service and the office of any municipality.
Can the consulate block my PESEL for me?
The law does not provide for this possibility, and the gov.pl pages do not mention the consulate in this context. The consulate will confirm the trusted profile and accept the report of the loss of the ID card, and the latter automatically blocks the PESEL from the office.
I do not have a Polish phone number. Can I create a trusted profile?
The Trusted Profile FAQ anticipates such a situation and directs you to the helpline +48 42 253 54 50 (weekdays, 7–18 Polish time) for number verification.
Can a stranger check that I have a blocked PESEL?
Yes, but they must know your PESEL number and the series and number of your last ID or passport (Article 23j, paragraph 2). The check is free and requires logging in. Anyone acting on behalf of a company must indicate it under penalty of criminal liability.
How do I know who checked my number?
In the mObywatel app, the button "Who Checked Your PESEL" (basis: Article 23l).
Does blocking PESEL protect my SSN in the USA?
No. Not at all. To protect your SSN, use credit freezes at Equifax, Experian, and TransUnion and report at IdentityTheft.gov.
How do BIK Alerts differ from blocking?
BIK Alerts are a paid commercial service of BIK S.A. that notifies about inquiries. Blocking PESEL is a free state register that prevents actions. You can obtain a copy of your data from BIK for free based on Article 15 of the GDPR. This is not the same as the paid BIK Report.
Will the bank return my money if it granted credit in my name despite the blocking?
The regulations do not mention the return of money, only the prohibition on pursuing claims from the consumer and the prohibition on transferring receivables (Article 105d, paragraph 3 of the Banking Law). There is an exception to this prohibition in case of system failure lasting longer than 15 minutes (Article 105d, paragraph 6). In case of dispute, judicial proceedings and individual legal advice may be necessary.
Can a child have a blocked PESEL?
The register collects data of adults (Article 23a, paragraph 2). For an adult without full legal capacity, the application is submitted by a legal guardian or curator.
