Rodné číslo, the Czech personal number; Slovakia uses the same scheme. The first six digits are the date of birth as YYMMDD. Women have 50 added to the month. Since 2004 (Act 53/2004) a further 20 is added to the month (70 for women) when the serial numbers of a day run out. Numbers of people born before 1954 have nine digits. Later ones have a tenth, check digit: the number is divisible by 11, except a few issued until 1985 whose first nine digits leave a remainder of 10 and that end in 0. It is usually written with a slash after the sixth digit. The Ministry of the Interior also assigns birth numbers to foreigners with long-term residence. Health insurance, social security and, by default, tax registration use it.
