Having a Baby in Poland as a Foreigner: Registration and PESEL

Having a baby in Poland as a foreign parent kicks off a short, fixed chain of paperwork: the hospital documents the birth, the registry office (Urzad Stanu Cywilnego, USC) draws up the Polish birth record, a PESEL number is assigned automatically, and - if the parents are not married - paternity may need to be formally recognized first. As of October 14, 2026, the rules sit in the Civil Registry Records Act (Prawo o aktach stanu cywilnego, consolidated text Dz.U. 2026 poz. 393). Here is the sequence, step by step.

Step 1: the hospital issues the birth card

Everything starts with the karta urodzenia (birth card) issued by the medical facility where the child is born. The Polish birth record is drawn up on the basis of that card (art. 53 ust. 1), and the health minister sets its form by regulation. The card travels from the hospital to the registry office system; you will be told at discharge how yours is transmitted.

Step 2: register the birth within 21 days

The birth must be registered at a USC within 21 days of the date the birth card is drawn up (art. 55 ust. 1). The deadline matters less than it used to, because there is a backstop: if you miss it, the USC head draws up the birth record ex officio from the birth card, notes that it was done ex officio, and informs the parents (art. 55 ust. 2). But letting the office do it alone has a real cost - if the parents do not choose a name, the USC head chooses one ex officio and the choice is annotated in the record (art. 56 ust. 2).

Who registers: the child's mother or father with full legal capacity (a parent aged 16-18 with limited capacity can also do it; otherwise a legal representative or the mother's guardian). You can also register through a proxy (art. 57). The registration is recorded in a protocol signed by you and the USC head.

The registration protocol includes your declaration of the child's name or names, the child's citizenship and your own citizenships, the parents' details and PESEL numbers where assigned, and the interpreter's details if one took part (art. 58). The birth record itself is normally drawn up on the day of registration - or the next working day if you file electronically (art. 52 ust. 1).

If the parents are not married: paternity first

If the mother is married, her husband is presumed to be the father and his data goes onto the record. If that presumption does not apply - the parents are not married - the father's details are entered only after paternity is recognized or court-established (art. 61).

Recognition (uznanie ojcostwa) is straightforward: the man declares before the USC head that he is the child's father, and the mother confirms, at the same time or within three months of his declaration, that he is the father (Family and Guardianship Code art. 73 §1, consolidated text Dz.U. 2026 poz. 236). Many couples do this before the birth or together with the registration. If recognition happens only after the birth record is drawn up, the record gets an additional annotation rather than a rewrite (art. 66).

If neither recognition nor a court ruling happens, the record lists the father's first name as indicated by the person registering - or as chosen by the USC head - and the mother's surname, with an annotation (art. 61 ust. 2).

Step 3: PESEL is assigned automatically

You do not apply for the child's PESEL. Under art. 16 ust. 1 of the Population Records Act (ustawa o ewidencji ludnosci, consolidated text Dz.U. 2026 poz. 384), the PESEL number is assigned ex officio - and the USC head is among the authorities who trigger the request for children born in Poland (art. 17). The number is then used everywhere: health care, benefits, school.

What citizenship does the child get?

This is the point that surprises many expat parents: a child born in Poland to two foreign parents does not become Polish by being born on Polish soil. Poland applies ius sanguinis - citizenship by blood. A minor acquires Polish citizenship by birth if at least one parent is a Polish citizen, or if born in Poland to parents who are unknown, stateless or of undetermined citizenship (Act on Polish Citizenship art. 14, consolidated text Dz.U. 2025 poz. 1611). Otherwise the child takes the parents' citizenship - or citizenships - and the parents handle the home-country registration (usually at their embassy or consulate) in parallel with the Polish paperwork.

What to arrange right after

With the birth record and PESEL in place, three practical items usually follow immediately for expat families:

• Health insurance for the baby - register the child under a parent's insurance route (through the employer, ZUS or an NFZ arrangement) so paediatric care runs smoothly from the first visit.
• Benefits - the universal 800+ child benefit and the family support programs apply to many foreign residents; see our guides on 800+ and the Aktywni rodzice benefits.
• Your home country's consular registration - for the child's foreign birth certificate, passport and, where applicable, citizenship confirmation.

Frequently asked questions

### How long do parents have to register a birth in Poland?

21 days from the date the birth card is drawn up (Civil Registry Records Act art. 55 ust. 1). If the deadline passes, the registry office draws up the record ex officio - and may choose the child's name itself.

We are not married. Will the father be on the Polish birth record?

Only after paternity is recognized or established by a court (art. 61). Recognition is done before the USC head: the father declares, and the mother confirms at the same time or within three months (Family Code art. 73 §1).

Does a baby born in Poland to foreign parents get Polish citizenship?

No, not by birth on Polish soil. Polish citizenship passes by blood: at least one Polish parent is required, unless the parents are unknown, stateless or of undetermined citizenship (Citizenship Act art. 14).

Do we need to apply for the baby's PESEL number?

No. PESEL is assigned ex officio for children born in Poland (Population Records Act art. 16).
