Under Salt Lake County Ordinance 1849 § 11, 03-19-2019:
It shall be the duty of the addressing agency to establish an addressing standards and definitions policy for the county, to provide requested addressing guidance from the incorporated cities, to approve alphabetic street names and maintain and create address point data countywide by fostering a collaborative relationship with the incorporated cities of Salt Lake County. The addressing agency will maintain address points through documented data and/or validated data provided by the municipalities addressing authority.

Using the correct address allows emergency service responders to locate the caller in optimum time, USPS to deliver the mail appropriately, and the public to easily find a location in the Salt Lake Valley. Some of the Addressing Office’s responsibilities include street name approval, reviewing and implementing recorded documentation, maintaining property locations, and coordinating addressing standards with the municipalities in Salt Lake County.

When we validate an address we are ensuring it is in a standardized format and in the correct location. We ensure there is a frontage (house) number, a directional (N, S, E, W), an appropriate street name and street type, and that the address is assigned to the appropriate parcel. We also check to make sure that the address is in sequence with the surrounding addresses and the odd/even house numbers are assigned on the correct side of the street. We also check that the address matches recorded documentation. We validate addresses to ensure the Post Office, delivery services and public safety can easily find your address.

The Addressing Office is responsible for validating every property address in Salt Lake County. We review all subdivision plats and address change documents recorded against properties in the county. We also use Building Permits and Business Licenses to help validate our address database. There are currently over 540,000 addresses in our system.

A mailing address is where you have your mail sent to, while a property address is the actual location of a property. Most of the time the mailing and property addresses are one in the same. Some people do not have their mail delivered to their property if they have a PO Box or if they own several properties and have all their mail sent to one location, not to the individual properties.

Contact us at (385)468-6760 and we can connect you with your city’s representative. To learn if your proposed street name is already in use please see our list of existing streets.

Alphabetic street names should be given to private streets, permanent dead ends, and any street which has intersection coordinates that shift more than five numbers along its entire length. Alphabetic street names should be approved prior to the recording of documentation (e.g., subdivision plats and affidavits). For more information visit our street name approval process page.
