Federal Information Processing Standards (FIPS) Code changes.

FIPS codes are unique to counties, parishes, boroughs and independent cities. For more information on FIPS codes, refer to the American National Institute (ANSI) Codes, maintained by the Census Bureau (www.census.gov/library/reference/code-lists/ansi/ansi-codes-for-states.html).

It is our job to ensure customers understand the changes and have the information needed to implement them. Customer notification messages are transmitted on NWS dissemination circuits:

If the Census Bureau implements changes in FIPS codes and / or the NWS implements a new six digit SAME location code, the NWS will issue Service Change Notices well in advance of the change.
