SSN Regex for 123-45-6789 OR XXX-XX-XXXX

Question

Can someone provide me a regex for SSN that matches either

123-45-6789

OR

XXX-XX-XXXX

I currently have ^\\d{3}-?\\d{2}-?\\d{4}$

Answer 1

To strictly answer you question:

^(123-45-6789|XXX-XX-XXXX)$

shoud work. ;-)

If you read the section "Valid SSNs" on Wikipedia`s SSN article then it becomes clear that a regex for SSN validation is a bit more complicated.

Accordingly a little bit more accurate pure SSN regex would look like this:

^(?!(000|666|9))\d{3}-(?!00)\d{2}-(?!0000)\d{4}$
