Poland Test Data Generator
Create synthetic Poland profiles for forms, demonstrations and localization tests.

Your first record will appear here shortly.
Copy individual values or export the entire result.
Synthetic identities; domains, addresses and numbers may coincide with real values. Do not contact or send payments.
Testing Poland interfaces
This locale uses pl definitions for names and presentation formats. Test text lengths, input handling, exports and Unicode support. City, region and available postal codes come from the same GeoNames locality. See the generated quality note for postal coverage; street and house number remain synthetic.
Testing Poland forms
Use a Poland profile as a starting point for form tests. This guide focuses on the two-plus-three postal split. Add the deliberate fixture below to make that behavior repeatable.
Generator locale: pl. Suggested application display locale: pl-PL. These are separate settings; this guide does not change the generator’s output.
Address reference for Poland
Polish postcodes contain five digits with a hyphen after the second digit. The UPU examples include zero-prefixed postal strings and apartment information.
The two-plus-three postal split
Test the postal separator and Unicode input together during a spreadsheet round trip. An ASCII search key may be useful, but it should not replace the original name or label.
A deliberate regression fixture
Editorial regression fixture — shape and preservation tests only country: PL postal_shape: "01-234" name_input: "Łucja" expected: Retain the hyphen and initial zero, and display the original Ł after reopening.
These editorial inputs are for controlled tests. They are not verified addresses, guaranteed unassigned contact details, or automatically generated examples.
- 01
Fixture assertion
Retain the hyphen and initial zero, and display the original Ł after reopening.
- 02
Original text
Add the hand-written input “Łucja” and compare it after saving, copying and CSV import. It is an editorial string, not promised generator output.

Locale and coverage
Test pl-PL display separately from the stored date-only value. Keep the generated locality coverage note with the record; the address reference does not expand Genory’s dataset.
Address reference: UPU addressing guide: Poland. Reviewed 4 October 2026. Postal presentation rules are not universal rules for storing personal names.
