Give this a try:
=SUMIF(A1:A2300,"PCO*",B1:B2300)

=SUMPRODUCT(ISNUMBER(SEARCH("PCO*",A1:A2300))*((B1 :B2300)))

Also, if you are just matching numbers, you may be able to use a Pivot Table:

Hello

I have two set of data. I have to match that both contain PCO12345.
All PCO# # # # are different. Majority are in both files but some of
the them are missing. There is no particular order. Is there any way
to find PCO # # # # that are in both files and which ones are
missing? I there any easy method like if statements? other than going
through each finding each PCOnumber one by one. There are 2300+
recods.

thanks in advance
