NGUID (NENA Globally Unique ID)

NGUID (NENA Globally Unique ID) is a globally unique ID generated and maintained within a GIS database by combining a “locally unique ID,” which may be numeric and/or text, and the “Agency Identifier” (a domain representing that authority, as defined in NENA-STA-010) of the 9-1-1 Authority, into a new single ID.
