What is a Polish ID number (dowód osobisty)?

A Polish ID number is a 9-character identification number issued to Polish citizens on their identity cards. It consists of 3 letters followed by 6 digits, with the last digit being a checksum for validation.

Are the generated ID numbers real or valid?

The tool generates numbers that follow the official Polish ID number format and have correct checksums, making them structurally valid. However, they are not real issued numbers and should only be used for testing and educational purposes.

What do the different parts of the ID number mean?

The first 3 letters encode gender and birth date: first letter indicates gender (M/F), next two encode birth year. The following 6 digits include region code, serial number, and checksum digit calculated using the Luhn algorithm.

Can I use these generated numbers for official purposes?

No. These are randomly generated numbers for testing and development only. They should not be used for any official identification, registration, or legal purposes.
