Default Using DCOUNTA to count only Unique values

I have a column containing hundreds of Project Numbers (e.g., P8763, PA3229,
P1090.1, etc.), and the same Project Number can appear more than once in the
column. I need to count the number of unique Project Numbers within that
column. Is there a way to do that? Any help would be greatly appreciated.
Thanks.
