Countif Criteria Reference Cell

[StephonM]

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.

What format are the phone numbers in?

(123) 123-1234
123-123-1234
123 - 123 - 1234
1231231234

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

digit numbers in the given range.

If the area code is always the three leftmost digits you may try
something like this:

=SUMPRODUCT(- -(LEFT(Contacts!H3:H229,3)=""&C4))

Hope this helps / Lars-Åke

Try it like this:

=SUMPRODUCT(--(LEFT(Contacts!H3:H229,3)=C4&""))
