About this Validator
This tool validates Bulgarian Personal Numbers for Foreigners (PNF/LNC - Личен номер на чужденец) according to the official format requirements.
The validator checks if a given PNF follows the correct structure and verifies the check digit using the official weighted checksum algorithm.
This validation only confirms if a PNF follows the correct format. It does not verify if the number is actually registered with Bulgarian authorities.
