US ZIP9 Coder Tool
Use US ZIP9 Coder to associate geographic coordinates with input ZIP9 (also known as ZIP+4) codes in an address file. This enables you to carry out geography-based analyses. The US ZIP9 Coder appends latitude and longitude, county and state FIPS code, and census tract and block number.
The US ZIP9 Coder tool requires a separate installation located on the Core Data Bundle installation disk.

The ZIP9 Coder only appends the above information to existing ZIP9 or ZIP+4 codes. It does not determine the correct ZIP9 or ZIP+4 code for the input address. The input data must already contain the correct ZIP9 or ZIP+4 codes.
If you use the CASS tool to determine the correct ZIP5 and ZIP+4 codes for the input address, you can then use the ZIP 9 Coder to assign a point object to the results.
