What is a 911 Address?

A 911 address is an assigned property number using the Century System property-numbering standard, which the American Society of Planning Officials recommends for rural areas. In this system, numbers are based on fractions of a mile, indicating distances along the road. Equal intervals of 1/100th mile (52.8’) are used, allowing up to 200 numbers per mile (100 per each side of the road.) An individual property number is determined by dividing the distances (in feet) from the property’s access point on the road to the starting point for the road by 52.8 (1/100th mile). The purpose of a 911 address is to ensure the location of a property and its accuracy for emergency service purposes as well as numbering individual properties as accurately as possible for mapping and possible future development.
