Hi,
I'm using the phone validation and got an issue with a client trying to use a phone number with prefix (NXX) 811, based on wikipedia page 811 is valid. https://en.wikipedia.org/wiki/List_of_North_American_Numbering_Plan_area_codes#500.E2.80.93599
I want to know if there is a reason for this behavior. I could send a pull request to allow 811.
