Regular expression to match a united states phone pattern

I want to validate a United States phone number, this is what I have so far:

var numberRegex = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/

My problem with this is that this allows single bracket.

This will allow to pass an opening parenthesis without a closing one like this: (111-121-1212.

Does anyone have a regex script that will match a U.S phone number and account for brackets?

I would advise against this. The only way to validate a phone number is too try and call it and see who picks up. A phone number may look syntactically correct, but it can still be semantically wrong (ie. a fake phone number).

The best you can do is give the user a warning that the phone-number "doesn't look valid" but accept any input anyway.

Use alternatives (|):

(?:
 \(([0-9]{3})\)
  |
 ([0-9]{3})
)

Resulting re looks like:

var numberRegex = /^(?:\(([0-9]{3})\)|([0-9]{3}))[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/
