Addressing Services
The Jefferson County GIS & Addressing Office manages addressing services throughout Jefferson County, including assigning addresses to structures, approving road and subdivision names, and maintaining County road signs.
The County’s addressing system supports reliable location identification for residents, businesses, emergency responders, and public services. For official requirements, review the E9-1-1 Addressing Ordinance.

How Are Addresses Assigned?
Jefferson County assigns addresses to structures where people live, work, or regularly spend time. Vacant parcels and structures that are not regularly occupied generally do not receive addresses.
Review the Addressable Structure Guidelines for details about which structures qualify for an address.

Find Property Ownership Information
The Jefferson County GIS & Addressing Office does not provide property ownership records. To find ownership information, contact the Jefferson County Assessor’s Office.

Email: assessor@jeffersoncountywv.org
Phone: (304) 728-3224
If you frequently need to verify property ownership, consider subscribing to the Assessor’s mapping website.
You may need the property’s tax information, including its District, Map, and Parcel numbers, to identify the correct location. If you have the property’s street address, the GIS & Addressing Office can help you find those numbers.
Addressing in Unincorporated Areas
In unincorporated areas, addresses are calculated based on the distance from the road’s starting point to the structure’s access point. The County follows the 5.28 addressing standard, which assigns one address number for every 5.28 feet, or 1,000 address numbers per mile.
Address numbers generally increase from south to north or west to east, depending on the road’s orientation. On dead-end roads, numbering begins at the start of the road regardless of direction. Odd numbers are assigned to the left side of the road and even numbers to the right.
For example, a structure located 7,438 feet from the starting point of Main Street would receive address number 1408.
Some sample addresses are shown below. If the distance from your home to the starting point of the road is X, then your address = Y.
| Distance (X) | = Address Number (Y) |
| 52 ft | 10 |
| 100 ft | 18 |
| 528 ft – 1/10 mile | 100 |
| 2640 ft – 1/2 mile | 500 |
| 5280 ft – 1 mile | 1000 |
Addressing in Incorporated Areas
Municipalities generally follow the County’s E9-1-1 Addressing Ordinance through local resolutions or agreements. The GIS & Addressing Office assigns address numbers within municipal boundaries and works with municipalities to approve new road names.
Addressing systems may follow the 5.28 standard or use a city-block system, in which numbers progress outward from the downtown center in blocks such as the 100 block and 200 block.

Road and Subdivision Naming
The Jefferson County GIS & Addressing Office provides final approval for road and subdivision names in unincorporated areas. Names within municipal boundaries must also receive approval from the applicable municipality.
New names must not duplicate or be confusingly similar to existing names. Road names must also use an approved road suffix.
