This is a Regex for South African ID numbers.

SA ID numbers' format is the following:

YYMMDD GGGG CAZ

YYMMDD is for the year, month and day. GGGG is for Gender: 0000-4999 is female; 5000-9999 is male. C is for Citizenship: 0 is born in SA and 1 is permanent residency. A is always 8, was used until the late 1980's to indicate race. Z is a strategically calculated number making the ID number valid or invalid using Luhn's algorithm.

This Regex also makes provision for spaces (people write ID numbers differently):

• 1234567890123
• 123456 7890 123
• 123456 7890 12 3

This Regex is also elsaticsearch compatible, I have test it in a lot of search engines, and it works every time.

Feel free to use this Regex.
