Addressing and Road Naming

Contact: Janelle Luppen

Addressing

Due to the need to maintain mappable road lines and address points for the 9-1-1 system, the Yellowstone County GIS Department has assumed the responsibility for road naming and the assignment of address numbers. Addresses for all new structures must be assigned or verified by the GIS Department, which can be done over the phone at (406) 869-3553 or by visiting Room 305 of the County Court House. There is no fee, and the GIS Dept. provides documentation of your legal physical address. Also, reflective address numbers will be provided free of charge upon your request, for posting at your property. It is important to establish your address with the GIS Department to ensure that your structure location is GPS’d for inclusion in the enhanced 9-1-1 map system and database. If you receive a new address assignment from another source such as from the Post Office or a developer, it may be in conflict with the physical address in the GIS database.

Road Names and Road Name Changes

The GIS Department is also involved in the review process for new subdivisions to make certain that proposed new road names are unique and that roads are named where necessary. A new guideline for road naming has been implemented to improve the capability of public safety personnel to locate citizens in an emergency and to reduce the need for future address changes in areas of growth:

A road should be named when it exceeds ¼-mile in length and/or provides exclusive access to three or more dwellings.
