Did you know? Your I.D. Number says a lot about you. E.g. : 861225 4621 08 1 The first six digits are the date of your birth in YYMMDD format. The seventh digit is the gender: 0-4 for Female, 5-9 for Male. The 8th - 10th digits are the series, which is your index in the number of people with that DOB/ Gender combo allocated (meaning how many babies were born on that particular day alll over Mzansi and you were baby number 123 etc.). The 11th digit is the citizenship number, which is 0 for South Africans and 1 for foreigners. The 12th digit is generally either 8 or 9, but this is not guaranteed. The 13th digit is a control digit, with a nasty algorithm to validate it. Calculate total A by adding the figures in the odd positions i.e. the first, third, fifth, seventh, ninth and eleventh digits. Calculate total B by taking the even figures of the number as a whole number, and then multiplying that number by 2, and then add the individual figures together. Calculate total C by adding total A to total B. The control-figure can now be determined by subtracting the ones column from figure C from 10. Where the total C is a multiple of 10, the control figure will be 0. Yeah I know, the 13th number doesnt make sense, and I have no idea what the 12th is, if you know,please let us know too. A curious mind is a healthy mind.
