Title: Very good

Thanks for the great regex, built on it a little but works great! just a heads up for future development it does not recognise the follow: - Spaces between digits (some people break up into common formats such as 01784 1...) - hyphen between the numbers (Netherlands). Otherwise great 5 stars from me!

I added the +1 option, fixed a bug with the hyphen between the 1 and the area code, and made the extensions more flexible. ^(1\s*[-\/\.]?\s*)?(\((\d{3})\)|(\d{3}))\s*[-\/\.]?\s*(\d{3})\s*[-\/\.]?\s*(\d{4})\s*(([xX]|[eE][xX][tT]?)\.?\s*([#*\d]+))*$

Does not accept numbers without area code like 333-4444.... Fixed by adding (....stuff for 1(333) areacode....)? to it

Title: '+1'

Does not accept numbers with a + in front of the 1 (as is customary for international codes), such as: +1 987 654 3210 Easily fixed with the addition of a \+? just before the 1. Thanks for a great RE!
