Federal, tribal, state, local, and non-governmental data partners continuously submit new features and edits to existing features in the Geographic Names Information System (GNIS). Additions and changes are validated by the staff and made available on the Search Domestic Names application.
Suggested data corrections from any source are accepted. They are reviewed and when validated, they will be committed to the GNIS. Send questions about the data and GNIS maintenance program to firstname.lastname@example.org.
