Canadian SIN

[BenW]

I have created a regex for Canadian SIN but I am getting false hits due to 0000 numbers.

 (\d{3}-\d{3}-\d{3})|(\d{3}\s\d{3}\s\d{3})

Hi BenW,

Can you try this:

([1-9]\d{2}-\d{3}-\d{3})|([1-9]\d{2}\s\d{3}\s\d{3})

0 is a valid number but not a string of zeros

Hi BenW,

According to this article http://id-check.artega.biz/info-ca.php, The first digit of a SIN indicates the province in which it was registered. Therefore any SIN number that starts with a zero would be fictitious. The regex that I provided earlier would ignore all SIN numbers that with a zero. That would also filter out a string zeros.
