Random Poland Address Generator

Poland writes its postal code with a hyphen after the second digit, a small formatting detail that breaks a surprising number of international address forms. The PESEL, meanwhile, packs birth date, century, sex and a checksum into eleven digits.

Test data only. This record describes no real person. Numbers are drawn from ranges reserved so they can never be assigned, and the address is not deliverable. Using synthetic data to impersonate anyone, open or verify an account, or evade identity checks is prohibited — see the terms.

How Poland addresses are structured

16 voivodeships (województwa). Not normally written in addresses — the postal code carries the routing.

Kod pocztowy format

Local namekod pocztowy
Format2 digits, hyphen, 3 digits
Example00-001
  • Always written with the hyphen — 00-001, not 00001.
  • The first digit identifies one of ten postal regions.
  • Central Warsaw uses the 00- prefix, so leading zeros are both real and common.
  • The system dates from 1973 and has been stable since.

Numbering planPolish Numbering Plan
Example+48 512 345 678
  • Nine digits with no trunk prefix — Poland removed the leading zero in 2009.
  • Mobiles begin with 45, 5, 6, 7 or 8; geographic numbers begin with 1, 2, 3, 4 or the remaining ranges.
  • Written in groups of three by convention.

PESEL

IdentifierPESEL
Example shape85010112345
  • Eleven digits encoding date of birth, a serial number, sex and a check digit.
  • The century is encoded by adding to the month: 20 for 2000s births, 0 for 1900s, 80 for 1800s.
  • The tenth digit is odd for men and even for women; the eleventh is a weighted checksum.

The identity numbers this page generates match the documented digit pattern so that form validation can be tested. They are not issued numbers, they correspond to no person, and they will not resolve against any authority.

Cities and voivodeships

The generator draws from these cities. Each is paired with the voivodeship it is actually in, and with the kod pocztowy prefix that area really uses — so a generated record is internally consistent rather than three unrelated values stuck together.

Frequently asked questions

Does the hyphen in a Polish postal code matter?

Yes. The canonical form is NN-NNN and Polish users will always type it that way. A validator with a five-digit numeric pattern rejects every genuine Polish postcode, which is one of the more common failures in address forms built US-first.

What does "ul." mean at the start of the street line?

It abbreviates ulica, meaning street. Other prefixes appear too — al. for aleja (avenue), pl. for plac (square), os. for osiedle (housing estate). They are part of the address, not decoration.

How does PESEL encode people born after 1999?

By adding 20 to the month digits. Someone born in January 2005 has 25 where the month would be. It is an elegant fix for a Y2K-style problem, and a good edge case for date-parsing tests.

What does 12/34 mean in the street line?

Building number 12, apartment 34. Polish addresses combine the two with a slash, so an address parser that treats the slash as a separator between fields will mangle it.
