Mineral County Mapping & Addressing is responsible for all of the 911 addressing in Mineral County. This office employs one part-time contractor. Many people don’t know but all 911 addresses are based purely on distance from the beginning of the road in which the home is located to the front of the house. The 911 addressing project began in 2004. The Office of Mapping & Addressing can be reached by calling 304-788-4111.
