| Description |
U.S. social security numbers (SSN), within the range of numbers that have been currently allocated. Matches the pattern AAA-GG-SSSS, AAA GG SSSS, AAA-GG SSSS, AAA GG-SSSS, AAAGGSSSS, AAA-GGSSSS, AAAGG-SSSS, AAAGG SSSS or AAA GGSSSS. All zero in any one field is not allowed.
** Additionally, spaces and/or dashes and/or nothing are allowed. In Michael Ash's example 123-45 6789 and 123456789 would fail there was a '\3' after the second octet of numbers that seemed to confuse the regex. now any combination of spaces, dashes, or nothing will work between the SSN octets. BoxerX.com thanks Michael for the regex! |

The is a bug in this regex that will allow 123-45Z6789 or 0123456789 (too many digits)

Title: The Purpose of \3

Joe, the purpose of the backreference \3 was to enforce the use of the same field separator throughout the string. You could use spaces or hyphens but not both.
