National Identification Number - Slovakia

Slovakia

In Slovakia there are currently two kinds of National identification number in use. The first one is the Birth Number (Slovak: Rodné číslo (RČ)), is issued at birth by the civic records authority (Slovak: matrika) and recorded on the birth certificate. Its format is YYMMDD/XXXX with YYMMDD being the date of birth and XXXX being a semi-unique identifier. For females, the month of the date of birth is advanced by 50. Full number (identification number - YYMMDDXXXX) must be divisible by 11. As this system does not provide a unique identifier (the numbers are repeated every century) it may be replaced by a meaningless identifier in the near future. The second system is the Citizen's Identification Card Number (Slovak: Číslo občianskeho preukazu (ČOP)) which is in the form AA XXXXXX (A-alphabetic, X-numeric) and is used on current ID cards. Identification Cards are issued by the state authorities (police) at 15 years of age for every citizen. In contrast to the Birth Number, this identifier can change over the citizen's lifetime if a new card is issued, for various reasons such as expiration, loss or change of residence. The ID number is used, among other things, for voter registration (because of the domicile record verification provided by the ID). A similar system, with both types of identification numbers, is used in the Czech Republic as well. In the Czech Republic is a new series of the Citizen's Identification Card Numbers (ČOP), which are in the format XXX XXX XXX (all numeric).
