Hi Marsha,
One way =SUMPRODUCT((A1:A200<"")/COUNTIF(A1:A200,A1:A200&"")) -- HTH RP (remove nothere from the email address if mailing direct) "Marsha" wrote in message ...

Run an autofilter, selecting "unique records". After, you merely need to
count the entries using the COUNT function. wazooli "Marsha" wrote: I need to be able to count information based on approximately 350 social security numbers, exlcuding duplicates. Any ideas on the formula? Thanks so much, Marsha |

At the risk of sounding studpid :) , do I enter this formual into the
destination cell, and then highlight my range and hit enter? I really don't do much with Exel except enter informtation. Thanks again.

No just enter it in any cell, and it will count the number of SS entries.
