Update 26 August 2010: A new and better version of this Excel file has been made available. Please go to South African ID Number Checker in Excel version 2 to get it.
Update 11 August 2011: Want this as an app for your smartphone? Click hereA 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:
- Valid Date
- Date is in the past
- Gender Flag
- Nationality Flag
- Check Bit
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.
