Less strict phone regex

Question

I want to validate a phone number with regular expressions in JavaScript.

I found lot of expression that match a specific pattern, such as xxx-xxx-xxx, but I'm looking for a less strict expression, that matches only numbers, and optionally -, , and + without restricting the number to a specific schema.

Answer 1

OK, so how about just:

/^[0-9\-,+]+$/

or, if you want to allow spaces too:

/^[0-9\-,+\s]+$/

You might also want to require that phone numbers have at least n digits, which you could do like this:

/^[\-,+\s]*([0-9][\-,+\s]*){n,}$/

where you need to replace the n with the minimum number of digits you want.
