Utilizing the Benefits of Enhanced 9-1-1
Hundreds of Maine communities are currently realizing the benefits of Enhanced 9-1-1 (E9-1-1). In order for the E9-1-1 system to continue to be effective, this information must be kept as accurate and up-to-date as possible. Correct and current E9-1-1 address data are needed to route emergency calls to the correct Public Safety Answering Point (PSAP).
The Addressing Officer is the representative designated by a community who is responsible for developing, creating and maintaining address information for the town. The Addressing Officer must be designated on an official form. A copy of this form and the E9-1-1 Addressing Officer Manual can be found at
The Addressing Officer has the authority to provide address information to the Department of Public Safety's Emergency Services Communications Bureau, local phone companies, and the E9-1-1 Service Provider. Below is a list of the changes and/or additions that need to be reported to make sure a community's road information is as up-to-date as possible.
After completing the initial addressing project, the Maine Office of Geographic Information Systems (MEGIS) provides each community with a maintenance map book. This map book is designed as a tool to be used in creating and maintaining each town's address information. This map book is an 11" X 17" representation of the community in map grid format which includes a geographical index and a road name index. The index can be referenced by road name and/or road section to the corresponding map grid/s where the road is located. This map book can be replicated and distributed to emergency personnel such as the local fire department, police department, and ambulance services. When E9-1-1 maintenance is completed, new map book page/s are created and provided to the Addressing Officer for replacement in the map book. This keeps the map book as up-to-date as possible.

Changes/Additions that Need to be Reported are:
The addition of a new street/road ( Example 1 & Example 2): Needed is the street name, the name of closest intersecting street, the address where the new road intersects. Also needed is the address range information for the new road and a brief description drawn on a copy of the map book page.
The extension of a street/road ( Example 1 & Example 2 ): When an existing street is extended in length, which affects the total address range. The new address range must be provided.
A street/road name change: ( Example ) When a road name changes, both the new road name and old road name are needed.
A deleted street/road ( Example 1 & Example 2 ): When a road is discontinued or is no longer passable, it should be reported so that the road is removed from the emergency road network.
An address range change: ( Example ) When the total or intersection-to-intersection range is changed on a street, the new address ranges must be provided.
When the location of a road is changed: ( Example ) If a roads location is found to be in error or the road alignment is changed enough to affect location or address information, a drawing depicting the change should accompany the maintenance form. Any resulting address range changes should also be reported.
