PESEL Number Generator

Online PESEL number generator and validator - quick creation and checking

Are you looking for a way to generate sample PESEL numbers or want to check in bulk whether the pasted numbers are correct? This tool combines a generator with a validator in one place and works without installation. You enter the parameters or paste the list, and the result is immediately in a readable format.

The interface is simple and clear. At the same time, it offers a complete set of options needed for tests, learning and demonstrations, so data preparation is no longer burdensome.

How the tool works and when it is useful

There are two modules working underneath. The generator randomly selects correct PESEL numbers depending on the selected date of birth, gender and number of records, and the validator checks the pasted strings, indicates correctness and reads the date and gender. This is not a database of real people. It is an educational and testing mechanism.

The tool is useful in several scenarios:

• Education and training- quick examples for validation and parsing exercises.
• Software testing- generating input data for forms and APIs.
• Documentation and demo- demonstration of how PESEL rules work in specific cases.

PESEL generator - date range, gender, uniqueness and output format

The generator can create numbers in a wide age range. Set one specific date of birth or indicate a date range and decide whether the gender should be any, male or female. These are simple settings, but give you a lot of control over the result.

• Year range- full possible range from 1800 to 2299. You can also enter a specific day.
• Gender- any, male or female. The last digit of the series is selected according to the parity rule.
• Uniqueness- enable if you want to avoid duplicates in the generated package. This is especially important in tests.
• Number of records- generate from 1 to 1000 numbers at once and see the result immediately.

You also have a choice of output format. Display the results as plain text, CSV or JSON and immediately copy to the clipboard or download the file. This saves time and eliminates manual rewriting.

PESEL validator - paste the list, check correctness and extract data

The second module is the validator. You paste multiple numbers, each on a separate line, and the tool checks the length, check digit, and date of birth. For correct numbers, the decoded date and gender are displayed. It's very convenient. You see the error immediately and know what to correct.

You can download the results as CSV or JSON, so they are great for analysis or importing into a spreadsheet. This speeds up the work and organizes the verification process.

Step-by-step instructions - from parameters to file download

Using the tool does not require specialist knowledge. Each step is described and the form fields are intuitive. Thanks to this, even a person who has contact with PESEL for the first time will quickly understand how the generator and validator work.

2. Set theparameters - in the generator, enter the date or date range, gender, number of numbers and decide whether they should be unique.
3. Select theformat - TXT for plain text, CSV for spreadsheets, or JSON for programming applications.
4. Generate result- click the button and see the result immediately.
