Thanks, I had been just looking for a regex I could copy because it looked a bit daunting but going through some of the tutorials it isn't all that bad. This is what I came up with if anyone else needs something like it:

$\d{3}$\s\d{3}-\d{4}(\s(x\d+)?){0,1}$

Help with Regular Expression

jjepen — Sat, 27 Oct 2007 05:05:05 GMT

I need help creating a regular expression that validates a US telephone number with or without extension. It needs to require an area code enclosed in parentheses and separated by a space, require a dash(-) between the prefix and the number, and allow an extension up to 4 digits(ex. x1234). Some matches and non-matches are provided below.

Match    (789) 555-1234
Match   (849) 555-1234 x1234
Match   (484) 555-8764 x1
Non-Match   789-555-7894
Non-Match   7895551234
Non-Match    (546) 555-1354 x12345
Non-Match   (345) 555-8794 x
Non-Match 756 468 4657

I've searched the net a found a few that claim to meet my requirements but under testing they all have some loophole that matches something it should not. Any help would be greatly appreciated.
