How many digits are in a geographic identifier?
Allows for codes up to 10-digits in length. The Census Bureau creates and maintains geographic codes for many statistical geographic areas that are not covered by FIPS codes and GNIS codes. These geographic areas include census divisions, census regions, census tracts, block groups, census blocks and urban areas.
How are geographic features codified in the GNIS?
Many cultural and physical geographic features are codified in the GNIS, including airports, beaches, cemeteries, churches, hospitals, islands, lakes, populated places, post offices, rivers, schools, streams and swamps.
