Possible Duplicate:
A comprehensive regex for phone number validation

I am pretty close to a full regex that I need. However I can’t seem to get an optional white space allowed.

Regex

^(\(?\d{3}\)?\-?\d{3}\-?\d{4})$

Requirements – Only these four

111-111-1111 – Works

(111)111-1111 – Works

(111) 111-111 – Doesn’t Capture

1111111111 – Works

How do I add an optional space after the parenthesis?

    How about \(?\b[0-9]{3}\)?[-. ]?[0-9]{3}[-. ]?[0-9]{4}\b which matches 3334445555, 333.444.5555, 333-444-5555, 333 444 5555, (333) 444 5555 and all combinations thereof.

    You’re running into the limitations of REGEX and so the ugly solution really is:

    (\d{3}-\d{3}-\d{4}|\(\d{3}\)\s?\d{3}-\d{4}|\d{10})

    Example
