Federal agencies use GLCs to report the location of real property assets in the Federal Real Property Profile Management System. GLC country codes come from the GeoNet Names Server (GNS) registry, which is maintained by the National Geospatial-Intelligence Agency (NGA), and state and county codes from the Geographic Names Information System (GNIS), which is maintained by the U.S. Just scroll down to the "Find Codes" section and click on "County and County Equivalents" or "State and State Equivalents." State codes (2 digits) and County codes(3 digits) are pre-determined by the U.S. General Services Administration's (GSA) Office of Government-wide Policy assigns and maintains GLC city codes for populated places and military geographic features. The Real Property Policy Division within the U.S. Use of these codes facilitates the interchange of data between Federal agencies, state, and local groups.
Announcement: GLC files on the site are updated by the 15th day of each month.Ī geographic location code (GLC) is an alphanumeric code that Federal agencies use to identify geographic locations.
