Whats the regex for

xxx-xxx-xxxx
or
(xxx)xxx-xxxx

I can create regex for the first one with

/^\d{3}-\d{3}-\d{4}$/

but how to add rule in this so it can also handle the second one?

Why not strip out everything that isn't a number, then check the length? — Rich Bradshaw, Dec 03 '12 at 08:20

You can use this: -

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

I'm no guru but this should do the trick;

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

Precisely, this will also match - `xxx-(xxx)xxx-xxxx`, but again it's not specified what OP don't want to match. So, it's a valid solution. – Rohit Jain Dec 03 '12 at 08:18
