Phone Number Validation with numverify

When we think about form validation, phone numbers aren't the most pressing bit of information to validate, but if the phone number is absolutely critical to your business or application, you'll want to do all you can to precisely ensure the number is correct.  And the truth is most single-input phone number elements aren't masked and don't ask for enough information so users provide their phone number with and without dashes, parens, and even without country or area codes, making the phone number field a bit of an unsanitized, abused field.

How can you do more advanced phone number validation and analyzation?  You can use numverify, a complete, reliable, easy to use phone number validation service!
