Enter your phone number (with area code) and then click "Check".
A phone number consists of a three-digit area code followed by a three-digit
exchange followed by a four-digit local number.
Variations are to permit
the area code to be with parenthesis, e.g. (905), and to permit any of the
characters ' '(space), '.' or '-' to separate the three parts, e.g.
123 456 9876, but the same character must be used in both places.
