ID Numbers?

[Just Dee]

Here's what the South African ID Number is made up of:

Format:
{YYMMDD}{G}{SSS}{C}{A}{Z}

YYMMDD : Date of birth.
G  : Gender. 0-4 Female; 5-9 Male.
SSS  : Sequence No. for DOB/G combination.
C  : Citizenship. 0 SA; 1 Other.
A  : Usually 8, or 9 [can be other values]
Z  : Control digit. There's a whole calculation for this last digit, based on all the preceding 12 digits.

This is 8 or 9 for the "new" Green ID book where as 0 thru 7 is for the old Blue ID book.
