Exactly same situation in Finland. Yet in Finland there has been discussion about replacing it. But the current system isn't perfect. Address space is limited, as well as the current system indicates your gender, which gender neutral people don't like too much. In Finland we do have check code. Valid check byte is '0123456789ABCDEFHJKLMNPRSTUVWXY'. Format is DDMMYY then separator (if CC==19 then - elif + CC==20 then +)NNNC where NNN is sequence number and C is check byte. NNN contains also sex in format of parity, and even sequence numbers are used for females. -> Creates a limit of 500 identities / day / sex. Full example: 0123456-7890
