NG Absolute Form Validator - V14.1

PhoneNo

The Phone No rule checks that a field holds a valid-looking phone number, using a built-in default pattern that expects more than 10 digits — a sensible starting point for a contact number, a support hotline field, or a signup form's mobile number field. Since real-world phone formats vary widely by country (dashes, spaces, parentheses, country codes, or a shorter local digit count), the rule accepts a custom regular expression in place of the default, so a form targeting a specific region or format can validate against the exact pattern it needs instead of the generic one.
