Within Europe there is no such system as European Social Security Number or European Identification Number. A lot of countries have their own system, and other countries are struggling to get a system into place.
The struggle of some countries has to do with historical reasons and with privacy aspects. Unique identifiation is not always used in favour of the community. And some of the used identification systems contain privacy-sensitive information, among others date of birth, gender and/or place of birth, where older systems might even contain religious or other privacy-senitive information.

In such a mechanism it is most common that part of the identification number is a 2-digit or 3-digit serial number to identify the unique male or female born on a specific date (or born on a specific month). Some countries provide odd serial numbers for male, and even for female. Bulgaria is the only one that wants “odd” females. Some countries like to divide on range (0-499 male, 500-999 female).
