Addressing Validation Workflow

Addressing is Salt Lake County’s principal steward of high-value spatial addressing data.
Its primary functions include validating and maintaining addresses countywide; along with assigning addresses for the unincorporated county, the metro townships, and Millcreek. This data is important for a wide variety of users including the Recorder, Auditor, Assessor, and Treasurer for use in mapping, tax assessment, and customer service. Addressing also maintains this data for use by cities throughout Salt Lake County and for the efficient dispatch of emergency services.

Where does the Address Information come from?
• Countywide subdivision plats are recorded with the Salt Lake County Recorder's Office.
• Addressing acquires a copy of the plat and extracts the address information from the recorded document. 
• Addressing organizes the information to be retrievable and useful for Salt Lake County and external agencies.  Subdivision plats provide a multitude of information, but for addressing purposes it provides the assigned address, street name, and intersection coordinate values.
