Cards issued before 1 January 2016 have nine digits and a letter: the two-digit birth year, the day of the year of birth (500 is added for women), a three-digit serial number, a check digit and V or X, which tells whether the holder may vote. Newer cards have twelve digits: the four-digit birth year, the day of the year (plus 500 for women), a four-digit serial number and a check digit. The check digit algorithm is not published.
