| Expression |
^(?=((0[1-9]0)|([1-7][1-7]\d)|(00[1-9])|(0[1-9][1-9]))-(?=(([1-9]0)|(0[1-9])|([1-9][1-9]))-(?=((\d{3}[1-9])$|([1-9]\d{3})$|(\d[1-9]\d{2})$|(\d{2}[1-9]\d)$)))) |
| Description |
I wrote this regular expression because a project I was working on required a stricter validator on social security numbers. There are actually gov't standards on what is a valid social: The first 3 digits can't be > 779, The first 3 digits can't be 000, The second 2 digits can't be 00, and the last 4 digits can't be 0000. This regex handles all these cases and checks formatting for numbering and dashes (###-##-####) |
