About this Validator
This tool validates Danish Personal Numbers according to the Civil Registration System (Det Centrale Personregister) requirements.
The validator checks if a given CPR follows the correct structure and validates the birth date and gender encoding.
This validation only confirms if a CPR follows the correct format. It does not verify if the number is actually registered with Danish authorities.
