A few days back I wanted to validate a list of ID numbers, and previously I have done the basics (length, date etc...) but I decided to do the full thing this time. So I search for the rules and found this post, which explains it nicely and contains some C# code. However for me C# didn't cut it as I wanted to process an Excel spreadsheet. So I whipped together a nice one which does the following checks:
  • Length
  • Valid Date
  • Date is in the past
  • Gender Flag
  • Nationality Flag
  • Check Bit
I've hidden the calculation cells so you can just unhide if you want to see the calculations. When I ran my list through it the failures came in two forms, obvious failures (things like 1000000000000) or check bit failures. Since I don't know which are real/valid in my list I am not sure if the check bit is 100%, but it did work fine for real ones I put in myself.
Anyway you can grab it below in the attachments section (You can grab the version 2 from the link above).

24 Jan 2010: I have disabled comments on this post as I am getting a lot of people asking me about who ID numbers belong to, how to track people based on ID's or what someones ID is. None of those I can answer as I do not work for the govt, police etc... If you have questions on the technical aspects of ID numbers please contact me using the contact form option.

All I can tell you is that it is someone born on July 29th 1985, is male and South African - cause that is all the information that the number has. If you want to track someone down speak to a lawyer.
