Description
This is for the Finnish social security numbers (henkilötunnus / hetu). It consists of eleven characters of the form DDMMYYCZZZQ, where DDMMYY is the date of birth, C the century sign (-,+, or A), ZZZ the individual number (even for men and odd for female), and Q the control character or the checksum. It is calculated DDMMYYZZZ mod 31, where the remainder 0,1,2,..,31 is converted from the list 0,1,...A,B,C..Y . The G,I, O and Q are not in the list, they are too similar to numbers 1, 8 and 0 (zero). Note: This regex does not calculate the checksum (mod 31). |

Try a slightly more simplified string and improved grouping like this:
^(0[1-9]|[12]\d|3[01])([0-1][1-9])(\d{2})(\+|-|A)(\d{3})(\d|[A-FHJ-NPR-Y])$

E.g. 110721A846E is a perfectly valid, yet this regex doesn't give a match.
BTW, the correct English translation for this ID is Personal Identity Code or PIC, not social security number.
