About this Validator
This tool validates Estonian Personal Identification Numbers according to official format requirements.
The validator checks if a given Isikukood follows the correct structure and verifies the encoded birth date, gender, and check digit.
This validation only confirms if an Isikukood follows the correct format. It does not verify if the number is actually registered with Estonian authorities.
