Address Number Methodology

If you need a physical address for a new structure, call the 9-1-1 Administrative Office at 618-439-0911.  A “physical address” is also known as an “official 9-1-1 address.”  When you call the 9-1-1 Administrative Office, make sure you have a physical address for a nearby structure to help us locate your site on the 9-1-1 Map.  We do not assign addresses to open land … your structure must at least be staked out so we can identify the approximate location of the center of the structure.

The addressing methodology used in Franklin County was adopted to enable our “first responders” to reach citizens requiring emergency services in the shortest time possible with the least amount of confusion.  For public safety reasons, we strive for consistency in our addressing of structures throughout Franklin County.  However, there is not complete consistency across the County.  For the most part, the cities, towns and villages in the County took responsibility for addressing the structures in their communities and the methodologies used are not the same in many cases.

Road Address Determination

Generally, primary structures in the County are addressed to the road they face unless there is no immediately identifiable access to the structure.  Consideration is given to the means of “access” to the structure if access is a substantial distance from the road it faces.  The optimal situation is when a structure faces the same road from which the driveway to the structure extends.  In the event that a structure is a substantial distance from the road it faces and there is no driveway from that road but there is a driveway from another road, the structure will be addressed to the road with the access. 

Address Number Determination

On East/West Roads, odd numbers are on the north side and even numbers are on the south side

On North/South Roads, odd numbers are on the west side and even numbers are on the east side

Address numbers increase as you travel north and as you travel east. 

Address numbers decrease as you travel south and as you travel west.

How You Can Help “First Responders”

Make sure your Address Number is displayed so that it can be seen from the road.  If your structure is a significant distance from the road, display your Address Number on your mail box or on a sign post at the end of your driveway.
