Address FAQs

How do you come up with the numbers you assign?

Our addressing scheme is based upon distance, every 5.28 ft is a potential address, each 1,000 numbers equal a mile. We normally start at the beginning of the road (the intersection closest to the center of the country), and using a distance measurement indicator (DMI), measure the distance to the center of the structure for which we are assigning an address. The resulting number is the 911 address. We deviate only to designate addresses on the left or right side of the road. Odd addresses are always on the left, and evens on the right.

For example: If you live at 1505 County Home Rd., you live slightly over one and one half miles on the left side.

The method of addressing is invaluable for our emergency responders. As soon as the dispatcher gives them the address, they know exactly how far down the road the house actually is and on which side of the road. The exception to this is that the City of Paris was addressed in a block system. We are currently working on converting the roads in the city to the 5.28 ft scheme.

Why do I need to have my house staked before you can assign an address?

When assigning numbers, the middle of the structure will determine the number. Structures should always be numbered according to the road they face, not where the driveway enters the road or where the mailbox is. An exception to this is when the house cannot be seen from the road, and then the driveway will be numbered and addressed on the road from which it departs. We also GPS (Global Positioning system) the house which gives us longitude and latitude coordinates. This helps us to pinpoint a caller if they happen to be using a cell phone.

How long does it take to get an address assigned?

We make every effort to get addresses assigned within a few days; however delays can occur due to out of town meetings and conferences. In the event your address is part of a new subdivision or private road, the road has to be named before an address can be assigned. Please see Addressing Rules and Regulations.

Is the address you assign also my mailing address?

Yes, but check with your local post office concerning where to locate your mailbox.

Now that I have the address, who do I need to give it too?

Make certain when you turn on your telephone service that you give them the correct address. When you dial 911 the information that is in their database is what we see at the 911 dispatch center. You will also need to provide the address to the board of public utilities, tax assessor, property assessor, election office, post office etc...

Why does my car GPS not put me in the correct location?

The commercial GPS market is enormous and not designed for public safety. The designated road points most of the time are not in the same locations as the designated beginning points used in public safety and 911. Our accuracy is more important than those in the commercial market because public safety has to be as accurate as possible to save lives, not to have a package delivered or to find a restaurant.

I have moved and I am unsure of my new address, how do I find out what it is?
