A code assigned to Postal Service facilities (primarily post offices) to collect cost and statistical data and compile revenue and expense data. The state number comprises the first two positions of the finance number.
The finance number can be used to match to records in other USPS files. By sorting these files by finance number, sequence matches can be made to use other street-level address information. For example, to use ZIP+4 product to obtain ZIP+4 codes for street addresses, a 5-digit ZIP Code, last-line number, or finance number for the street address must be known. The finance number can be obtained from the City State product.
For a street address such as "123 MAIN ST, SAN FRANCISCO CA," matching to the City State product will not provide a single 5-digit ZIP Code because San Francisco has more than one ZIP Code (i.e., it is a "multi-coded city"); However, the finance number for San Francisco can be obtained from the City State product. Then, by sorting the ZIP+4 product into finance number and street-name sequence, a match can be found to provide both the correct 5-digit ZIP Code and ZIP+4 code.
