Malaysia
In Malaysia, a 12-digit number (format: YYMMDD-SS-###G, since 1991) known as the National Registration Identification Card Number (NRIC No.) is issued to citizens and permanent residents on a MyKad. Prior to January 1, 2004, a separate social security (SOCSO) number (also the old IC number in format 'S#########', S denotes state of birth or country of origin (alphabet or number), # is a 9-digit serial number) was used for social security-related affairs.
The first group of numbers (YYMMDD) are the date of birth. The second group of numbers (SS) represents the place of birth of the holder - the states (01-13), the federal territories (14-16) or the country of origin (60-85). The last group of numbers (###G) is a serial number in an unidentified pattern which is randomly generated. The last digit (G) is an odd number for a male, while an even number is given for a female.
