Can I freeze my PESEL number?
Yes: freezing your PESEL protects you from loan fraud. A PESEL freeze means entering your number into the reservation register run by the Ministry of Digital Affairs. You can do it free in the mObywatel app, at a municipal office, or at a bank or post office. Since 1 June 2024 financial institutions must check the register — if they grant a loan despite a frozen PESEL, they can't effectively pursue the debt (from you or your successors). The freeze also blocks, among others, withdrawing a large amount of cash at a branch, signing a notarial deed, or getting a duplicate SIM. When you need to do such a thing, you can lift the freeze (ideally at least 30 minutes before) and then turn it back on.
📋 The rules
- Freeze = entering the PESEL in the reservation register
- Freeze in mObywatel, an office, a bank, the post office — free
- Since 1 June 2024 banks must check the register
- A loan on a frozen PESEL: unenforceable for the bank
- You can lift the freeze for a given action
🔓 Exceptions
- Lifting the freeze: for e.g. taking a loan or a notarial deed
- Some actions (large withdrawal, SIM duplicate): need the freeze lifted first
- Benefits (e.g. pension payment, healthcare): the freeze doesn't block them
⚠️ Penalties & fines
Freezing your PESEL carries no penalties — it's protection, not a duty. If a financial institution ignores the freeze and grants a loan, it bears the consequences: it can't pursue repayment, and you aren't liable for an obligation taken out on your data. Remember, though, the freeze also hampers your own actions (a loan, a notarial deed, a large withdrawal) — before them you must lift it. To protect against fraud: freeze your PESEL (e.g. in mObywatel) and keep it frozen day to day, lift the freeze only for a specific, planned action (at least 30 minutes ahead), and turn it back on afterwards. Also react to alerts about attempts to use your data.

❓ Frequently asked
How do I freeze my PESEL number?
Free — in the mObywatel app (the "Freeze PESEL" service), at any municipal office, and at many banks and Polish Post branches. The freeze means entering the number into the reservation register run by the Ministry of Digital Affairs and takes effect immediately.
Does freezing PESEL protect against a loan on my data?
Yes. Since 1 June 2024 financial institutions must check the reservation register. If they grant a loan despite a frozen PESEL, they can't effectively pursue the debt — from you or your legal successors. It's real protection against fraud.
What does a frozen PESEL block?
Among others, concluding a loan agreement, signing some notarial deeds, withdrawing a larger amount of cash at a bank branch, or getting a duplicate SIM. It doesn't block the payment of benefits, such as a pension, or the use of healthcare.
How do I lift the freeze when I need a loan?
You lift it the same way you set it — e.g. in the mObywatel app. It's best to do it ahead of time, usually at least 30 minutes before the planned action. After the matter is done, it's worth turning the freeze back on to stay protected day to day.
Is freezing a PESEL paid?
No. Freezing and lifting the freeze on a PESEL number are free. You can do it repeatedly — keep protection on day to day and lift it only for specific actions requiring identity confirmation, such as a loan or a notarial deed.
