The formula depends on how your phone numbers are formatted and whether they
are text or actual 10 digit numbers. For example, if they are text and you
simply need the first 3 numbers in the cell, try:

=SUMPRODUCT(--(LEFT(A1:A10,3)={"214","972"}))

If the area codes are enclosed in parentheses, you could use:

=SUM(COUNTIF(A1:A10,{"*(214)*","*(972)*"}))

Posting some examples will help readers give you a formula that works.
