The PVN is a 11-digit number that can either be a reference to a legal entity (in which case the first digit > 3) or a natural person (in which case it should be the same as the personal code (personas kods)). Personal codes start "32". Older personal codes start with 6 digits to denote the birth date in the form ddmmyy.
