The structure and data elements of each record type (9-digit ZIP, 5-digit ZIP and Address level) are the same. However, the record types will not necessarily have data in each field.  The following table illustrates the table structure and shows which fields are available in each record type. All data elements, including those that are null (no value), are required and have been included in the boundary database. A placeholder (comma) is included for null data elements.

FIPS Codes
Federal information processing standards codes (FIPS codes) are a standardized set of numeric or alphabetic codes issued by the National Institute of Standards and Technology (NIST) to ensure uniform identification of geographic entities. FIPS codes are used heavily by federal, state, regional and local government. The entities covered include: states and statistically equivalent entities, counties and statistically equivalent entities, named populated and related location entities (such as city, places and county subdivisions).

A FIPS Code is used to associate each boundary to the corresponding tax rates. More information on FIPS Codes is available at
the  NIST   website.
