123 - 123 - 1234

Do any of the area codes start with leading 0s?

How can I use Countif to allow me to reference a cell that contains the
area
codes of phone numbers to be counted? Below is my feble attempt:

=COUNTIF(Contacts!H3:H229,C4&"*")

where, C4 is the cell that contains the area codes to be searched. The
"*"
must be employed, as the area code is only the beginning 3 digits of
the
10
digit numbers in the given range.
