This tag holds a unique identifier from the USA Federal Geographic Names Information Service (GNIS). As documented at

The database assigns a unique, permanent feature identifier, the Feature ID, as the only standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. The GNIS collects data from a broad program of partnerships with Federal, State, and local government agencies and other authorized contributors... Any person or organization, public or private, may make inquiries or request the Board to render formal decisions on proposed new names, proposed name changes, or names that are in conflict.

Best practice is to copy this tag to new geometry that represents the same feature. Please do not remove this tag from an object without understanding the implications. If an object no longer exists it is considered appropriate to delete the entire object including the identifier.
