Understanding PESEL Numbers
PESEL Structure
Century Encoding
Checksum Calculation
Formula: A×1 + B×3 + C×7 + D×9 + E×1 + F×3 + G×7 + H×9 + I×1 + J×3
Step 1: Multiply each digit by its corresponding weight
Step 2: Sum all the results
Step 3: Take the last digit of the sum
Step 4: Subtract from 10 (if result is 10, checksum is 0)
Example: PESEL 80010112345
8×1 + 0×3 + 0×7 + 1×9 + 0×1 + 1×3 + 1×7 + 2×9 + 3×1 + 4×3 = 8+0+0+9+0+3+7+18+3+12 = 60
Last digit: 0, Checksum: 10-0 = 10 → 0

Frequently Asked Questions
PESEL (Powszechny Elektroniczny System Ewidencji Ludności) is the Polish national identification number system. It's an 11-digit number that uniquely identifies every person in Poland and contains information about birth date, gender, and includes a checksum for validation.
Generated PESEL numbers are for testing, educational, and development purposes only. They should never be used for fraudulent activities, official documents, or any illegal purposes. Always use official channels for legitimate PESEL registration.
Our PESEL validation is 100% accurate according to the official Polish algorithm. It checks format correctness, date validity, century encoding, gender consistency, and checksum calculation. However, it cannot verify if a PESEL is actually assigned to a real person.
Yes, this tool is perfect for software testing, development, and QA purposes. You can generate valid test data, perform batch testing, and validate PESEL handling in your applications without using real personal data.
