The CPR is the national number to identify Danish citizens and is stored in the Det Centrale Personregister (Civil Registration System). The number consists of 10 digits in the format DDMMYY-SSSS where the first part represents the birth date and the second a sequence number. The first digit of the sequence number indicates the century. The numbers used to validate using a checksum but since the sequence numbers ran out this was abandoned in 2007. It is also not possible to use the checksum only for numbers that have a birth date before that because the numbers are also assigned to immigrants.
