Information of a new street address is provided to the MSAG Coordinators in the planning stages. The Orange County Growth Management & Environmental Resource Department, or the affected Growth Management/Community Development Department of a municipality located within Orange County provides the information to the MSAG Coordinators. Usually new street addresses are added with new developments?whether residential or commercial. It is the responsibility of the MSAG Coordinator to check the current database to make sure that the new street names submitted, are not currently in use ? thus creating duplication of street names and/or "sound alike" street names. The MSAG Coordinator also assigns the correct Emergency Service Number (ESN). The ESN routes a 9-1-1 call to the correct Public Safety Answering Point (PSAP), also known as a 9-1-1 Call Center. 

As development and annexations occur, the MSAG Coordinator may have to increase an address range, change the name of a street, change the name of a community or an ESN.

The MSAG Coordinators work as a liaison between the PSAPs and the telephone companies to assure all street addresses and information is correct?so that when a 9-1-1 call is placed, the callers telephone number and correct address appears on the 9-1-1 Operator's computer screen. If incorrect information or no information is displayed, the 9-1-1 Operator submits a 9-1-1 Inquiry Form to the MSAG Coordinators. The MSAG Coordinators then work with the appropriate telephone company, government agency and/or citizen to correct the information.
