Why is my address being changed?

Address changes can result from a variety of factors, including but not limited to, road renamings, drive way access changes, new development, and parcel changes. Any time an address is changed, the property owner will receive written notification of the change.

Who does the County notify when they change my address?

Columbia County GIS will notify both regional and local postmasters, Columbia County Tax Assessor’s, Columbia County Water Utility, Columbia County Fire Rescue, and 911 of a change in address. The property owner will be responsible for updating accounts with any other service providers.

How can I make sure 911 has the correct address tied to my home phone number?

If you have a landline, you can contact 911 at 706-541-2800 for a test call to verify the address linked with your phone number.

How is an address determined?

An address is determined by the driveway access location for emergency response purposes. Emergency responders need to find you as fast as possible. Ensuring your address matches your driveway access location helps reduce response times.

What is the address numbering system?

Even numbers appear on the left side of the road while odd numbers appear on the right side of the road in the ascending direction.  We determine “ascending direction” based on where the addresses begin, usually from the intersection where the road begins. Dead-end streets have numbers assigned increasing from the originating intersection and ending at the end of the road way. As for roads that have access or intersections on either end, the originating intersection will be from the roadway with the most predicted traffic.

What if I have multiple structures on my property?

The primary structure on a property will have the same number assigned to it as the real property/land. Every additional structure with more than one principle use or occupancy will have a separate number for each use or occupant. For example, duplexes will have two numbers assigned.

What if a road crosses a County or city boundary?

Whenever a road crosses a municipality boundary, we will continue the address numbers as feasible to create a fluid transition.

What if I am demolishing and rebuilding or building a residence or structure?

It is the responsibility of the owner to contact Columbia County GIS to have an address number assigned before a permit can be issued. Addresses cannot be assigned before final plat approval by the Columbia County Planning Commission in new subdivision developments; addresses are assigned and recorded on the final plat of a subdivision development.

Now that I have my address number, what are the requirements for displaying it?

The rules for displaying your address number varies based on whether it is for a commercial or residential structure.

If you are posting numbers for a single family residence, you should display it on a fence/wall/mailbox post approximately 4 feet tall near the driveway access entrance. The numbers should be unobstructed and visible from both directions of the road. Also, the numbers should be at least 3 inches tall to aid in legibility from the roadway. We recommend reflective numbers to increase visibility. Reflective numbers can be purchased through various organizations, including the Columbia County Fire Rescue headquarters at 3910 Desoto Drive.

If you are posting numbers for a multi-family residence, like a duplex, the number should be displayed on the structure itself within 5 feet of the front door and visible from the road (where practical). Also, the numbers should be at least 3 inches tall to aid in legibility from the roadway.

Commercial structures require numbers that are at least 4 inches tall to be posted on the structure itself within 5 feet of the front door and visible from the roadway. 

What if I live on a private drive?

If a residence is on a private drive that serves more than one structure, the address number should be posted on the main road for emergency responders in addition to posting it near the driveway access off of the private drive. If a structure has more than one address assigned, for multiple uses or duplexes, numbers should be displayed near the front door as well.

What if I have more than one address number assigned or displayed?

The only address number that should be displayed is the one that has been officially assigned by the Columbia County GIS Department.

How do you decide if a roadway needs to be named?

A road that serves three or more structures or lots will be named regardless of ownership (public or private).

How do you decide what name to give a roadway?

We avoid any same or similar sounding road-names when assigning road names to reduce confusion in emergency situations.
