City Code

Description

The census city code within whose incorporated boundary the site resides.

This field is automatically derived from the US Census geospatial database using the user-provided Latitude and Longitude. If City Code is provided by the user, it will be compared to the derived value, and a warning will be issued if the values do not match, but the transaction will be processed without error. (The derived value will be stored in the database and the provided value discarded.)

If the site is not within a city, leave this field blank or use code 00000.
