About this Validator

This tool validates Canadian Social Insurance Numbers according to Employment and Social Development Canada's requirements.

The validator checks if a given SIN follows the correct structure and verifies the check digit using the Luhn algorithm.

This validation only confirms if a SIN follows the correct format. It does not verify if the number is actually registered with Canadian authorities.
