Javascript Regular Expression for International Phone Number

Question

The following regular expression isn\'t working for international phone numbers that can allow up to 15 digits:

^[a-zA-Z0-9-().\\s]{10,15}$

W

Answer 1

and then counts if there are at least 7 digits (minimum length for a valid local number).

The shortest local numbers anywhere in the world are only two or three digits long.

There are many countries without area codes.

There are several well-known places with a 3 digit country code and 4 digit local numbers.

It may be prudent to drop your limit to 6 or 5; just in case.
