How PIS/PASEP Validation Works

What does the validator check?

The Help4Dev PIS/PASEP validator checks whether the check digit (last digit) of a PIS or PASEP number is mathematically correct by the official algorithm. Weights 3, 2, 9, 8, 7, 6, 5, 4, 3, and 2 are applied to the 10 base digits, the sum is calculated, and the expected verifier is determined by modulus 11. The validator does not query Caixa Econômica Federal or eSocial databases.

When is a PIS/PASEP considered invalid?

A PIS/PASEP is invalid when: (1) it does not have exactly 11 digits (formatted or unformatted); (2) the check digit (last digit) does not match the calculation with weights and modulus 11 applied to the previous 10 digits. The validator processes the number with or without punctuation automatically.

Why validate PIS/PASEP in development?

HR systems, payroll, eSocial, labor benefits platforms, and tax declaration applications need to validate PIS/PASEP. Testing these systems with varied data — both valid and invalid — is essential to ensure validation robustness. The Help4Dev validator facilitates this process by providing instant results without needing to query real databases.
