Foreigners can get a Polish PESEL number in two ways. If you register your residence in Poland, a PESEL is assigned automatically. If you cannot register your residence but an office requires a PESEL from you, you can apply at any municipal office, with a hand-signed form, your identity document and the legal basis that requires you to have the number. The service is free. A PESEL is an identification number, not a permit, but it makes many things easier, including creating a trusted profile to sign residence applications online. This guide explains both routes, what to bring, what PESEL is used for and the problems foreigners most often meet. All information was checked on 11 November 2026 against official Polish sources.

What PESEL is

PESEL is the 11-digit identification number of the Polish population register. It encodes the holder's date of birth and sex, followed by a serial number and a check digit. Polish citizens receive it at birth. Foreigners receive it when they register their residence or, in some cases, on application. Offices, employers, healthcare providers and many private services use the number to identify people.

A PESEL does not give you any right to stay or work in Poland. Those rights come from your visa, residence permit, work permit or other legal basis. Do not confuse the number with a residence title.

Route 1: automatic assignment through address registration

The government service page for foreigners explains that if you live in Poland, you can register your residence and you will then automatically be assigned a PESEL (gov.pl). Address registration (zameldowanie) is done at the municipal office for the place where you live. Bring your passport and the documents your office asks for, such as proof of your right to occupy the property.

This is usually the simplest route if you have a stable address. It also means your address is recorded, which can help with other procedures. For example, if you are granted a temporary residence permit, your residence card will show an address only if you submit confirmation of your address registration within 14 days of receiving the decision (Wielkopolska Voivodeship Office).

Route 2: applying for a PESEL

When you can use it

If you are unable to register your residence and an office requires a PESEL from you, you submit an application to any municipal or township office (gov.pl). Typical examples are a person who is staying temporarily in short-term accommodation, or who has just arrived and needs a PESEL for a specific procedure.

The legal basis

The application must state the actual legal basis for your obligation to have a PESEL number. The Warsaw city service highlights this requirement on its page for foreigners from outside the EU (City of Warsaw). The Szczecin city office adds that if an office, for example the social insurance authority or a tax office, requires a PESEL from you, the application should also indicate the legal basis (City of Szczecin). Ask the office that requires your PESEL to tell you the provision, or to give you a document that states it.

What to bring

• The application form for a PESEL number, completed and signed by hand (gov.pl).
• Your passport or another document confirming your identity and the data in the application.
• A document showing the legal basis, if you have one, such as a letter from the office that requires your PESEL.

The government page publishes instructions on how to complete the form, which is in Polish. Fill it in carefully, using the exact spelling of your name from your passport.

Cost and timing

The service is free. The Szczecin city office explains that the clerk takes the application right away and, if there is a basis for assigning a PESEL, you receive a notification that the number has been assigned (City of Szczecin).

What PESEL is used for

Signing residence applications online

Since 27 April 2026, temporary residence applications are filed only through the MOS portal (Wielkopolska Voivodeship Office). You sign them through login.gov.pl, with a trusted signature, a qualified electronic signature or a personal signature (MOS portal). A trusted profile requires a PESEL, and the Poznań office advises applicants who do not have a trusted profile to obtain a PESEL and create one (Wielkopolska Voivodeship Office). See how to apply for a Polish residence permit online.

Work and social insurance

Employers use your PESEL when they register you for social and health insurance, which must be done within 7 days of the start of work (Social Insurance Institution). See social security registration for foreign workers in Poland.

Taxes and everyday services

PESEL is widely used in dealings with tax offices, healthcare providers, banks and mobile operators. Having one usually makes these procedures much simpler.

PESEL UKR and CUKR

Ukrainian citizens under temporary protection have a PESEL with UKR status. That status is linked to temporary protection and follows special rules. Ukrainian citizens who move to a CUKR residence card see their status change from UKR to CUKR in the PESEL register (Office for Foreigners). See our guide to the CUKR residence card.

Common problems and how to avoid them

"The office refused my application"

The most common reason is that the application does not state a legal basis for the obligation to have a PESEL. Ask the office that requires the number to give you the provision in writing, then apply again.

"My name is spelt differently"

Use exactly the spelling in your passport, including any diacritics. Different spellings in your PESEL record, your contract and your residence documents can cause problems later.

"I moved and my address is out of date"

Register your new address where the rules require it. An out-of-date address can mean you miss official letters.

"Someone offered to get me a PESEL for a fee"

The service is free and you can apply yourself at any municipal office. Be cautious of anyone who charges for it, and never share your login details for government services. See how to spot a fake job offer for Europe for broader warning signs.

Step by step: applying for a PESEL

1. Check whether you can register your residence. If you can, do that instead, and the PESEL will follow automatically.
2. If you cannot, ask the office that requires your PESEL for the legal basis in writing.
3. Download the application form and instructions from the government service page.
4. Fill in the form in Polish, using your passport spelling, and sign it by hand.
5. Go to any municipal office with the form, your passport and the legal basis document.
6. Keep the notification of the number when you receive it.

Worked examples

A worker who registers an address

A worker from Vietnam rents a flat in Poznań for a year. She registers her residence at the municipal office, and a PESEL is assigned automatically. She gives the number to her employer for insurance registration and uses it to create a trusted profile.

A worker in temporary accommodation

A worker from Nepal lives in short-term workers' accommodation and cannot register his residence. His employer needs his PESEL for insurance purposes. He asks the employer for a letter stating the legal basis, then applies at a municipal office with the form, his passport and the letter. The clerk accepts the application, and he receives a notification of his number.

A student who needs to sign online

A student wants to file a residence application through MOS and sign with a trusted profile. Without a PESEL, she cannot create one. Following the Poznań office's advice, she first obtains a PESEL and then creates the trusted profile before filing.

PESEL and the trusted profile

A trusted profile (profil zaufany) is a free electronic identity used to sign documents and access public services online. It is one of the ways to sign MOS applications through login.gov.pl. Because a trusted profile requires a PESEL, foreigners who want to sign residence applications this way should obtain a PESEL first (Wielkopolska Voivodeship Office). A qualified electronic signature is an alternative if you already have one. Keep your login details private. Anyone with them can act in your name.

Where PESEL appears in your documents

• Your employment contract and payslips.
• Your social insurance registration.
• Your tax documents.
• Your residence application and, later, your residence card details.
• Your healthcare records.

Using the same number and the same spelling of your name across all of these makes your records consistent and easier to check.

For employers

Employers often need a worker's PESEL for insurance registration and payroll. If a new foreign worker does not have one and cannot register a residence, the employer can help by giving the worker a written statement of the legal basis that requires the number. Do not delay the 7-day insurance registration while waiting for a PESEL. Ask the Social Insurance Institution how to register a worker who does not yet have one.

• The voivodeship office handling your case can answer questions about residence procedures and deadlines.
• The MOS portal has a contact form for questions about residence procedures and the portal itself (MOS portal).
• Your municipal office handles address registration and PESEL applications.

If you have more than one record

Occasionally, a foreigner ends up with records that do not match, for example because a name was transliterated differently on two occasions. If you notice that your PESEL record shows different personal data from your passport, ask the municipal office how to correct it. Do not apply for a second PESEL. Correcting the existing record keeps your documents consistent.

PESEL and children

Children of foreigners living in Poland can also receive a PESEL, for example through address registration with their parents. A child's PESEL is useful for school enrolment, healthcare and family health insurance through a parent. Check with the municipal office which documents are needed for a child.

After you have a PESEL

• Create a trusted profile if you will need to sign documents online.
• Give the number to your employer for social insurance registration.
• Use it consistently in all official forms.
• Keep the notification with your other personal documents.

Your next steps

1. Decide whether you can register your residence. If yes, do so and receive the PESEL automatically.
2. If not, ask the office that needs your PESEL for the legal basis in writing.
3. Download the form and instructions from the government service page.
4. Apply at any municipal office with your passport and the signed form.
5. Use your PESEL to set up a trusted profile if you will sign documents online.

Using PESEL safely

Your PESEL is personal information. Give it to employers, public offices, healthcare providers and banks when they need it, but be cautious about sharing it with people you do not know, especially together with a copy of your passport. Combined, these details can be misused to open accounts or sign contracts in your name. If you think your PESEL has been misused, report it to the police and contact the institutions involved.

When your circumstances change

Your PESEL number does not change when you move, change jobs or receive a new residence card. Update your address registration when you move, and give the same PESEL to your new employer. If your name changes, for example after marriage, ask the municipal office how to update your record.

If you are helping a family member or colleague, remember that the PESEL application is personal. They can apply at any municipal office with their own documents, and the service is free, so there is no need to pay anyone to arrange it.
