Before you write
You can check the postal code for your address using the search on the home page – just enter a postal code, locality, street or district. If a code is missing from the database, let us know and we will add it with the next data update.
Do not include sensitive information in your message (such as a PESEL number, phone number or another person’s mailing address).
