About this Validator
This tool validates Swedish Personal Identity Numbers according to official requirements.
The validator checks if a given Personnummer follows the correct structure and verifies its checksum using the Luhn algorithm.
This validation only confirms if a number follows the correct format. It does not verify if the number is actually registered with Swedish authorities.
