per call · USD Coin on Base

Offline validator/normalizer for a Danish CPR-nummer (personal identification number, format DDMMYY-SSSS). Checks digit count and date-of-birth validity, determines century from the 7th digit per official rules, and derives birth date and gender (last digit odd=male, even=female). Does not rely on the modulus-11 checksum since it has not been guaranteed valid for numbers issued since 2007.
