RegExLib.com - The first Regular Expression Library on the Web!

Regular expression for validating US telephone numbers with OPTIONAL area code, and OPTIONAL extension. Matches various permutations of formatting characters (parenthesis, space, dash). Parses the telephone number area code, prefix, suffix, and extension to named groups to facilitate program manipulation. Area code is optional and can optionally be enclosed in parentheses. Rejects area codes that begin with 0 or 1 and prefixes that begin with 0. Extension is optional and can be optionally preceded by a space and/or "x" or "X", and matches on 2 to 4 digits. Rejects all telephone numbers that do not match on exactly 7 digits, or on exactly 10 digits with the optional area code, not counting the extension or the formatting characters.

This validates the states and territories of the United States in a 2 character uppercase format. Very poor excuse for a regular expression! ;) Written by Jason Gaylord.
