Title: Tried all US RegExp phone options on this site. This is the best.

Tried all US RegExp phone options on this site. This is the best. This one does the best job of limiting to 10 characters while permitting (and limiting to) normal punctuation and allowing optional extensions

Great example but don't forget to put in the "/" char in front and back.

^(\(?\d{3}\)?)?( |-|\.)?\d{3}( |-|\.)?\d{4,4}((|-|\.)?[ext\.]+ ?\d+)?$ or for the US.. /^(\(?[1-9]{1}\d{2}\)?)?( |-|\.)?\d{3}( |-|\.)?\d{4,4}(( |-|\.)?[ext\.]+ ?\d+)?$/

I would change it to this for USA validation ^(\(?[1-9]{1}\d\d\)?)?( |-|\.)?\d\d\d( |-|\.)?\d{4,4}(( |-|\.)?[ext\.]+ ?\d+)?$ notice [1-9]{1} this makes sure that the first digit is any number 1-9 and not 000
