RESO Universal Property Identifier (UPI) Survey Results

The RESO UPI Workgroup embarked on a member survey to help them navigate where to go next with UPI and UPI Registry expansion. View and download the survey report here:


We will do a brief analysis of the survey results in a future blog post.

As a refresher, the UPI is a standard way to reference a property. The specification developed by RESO includes support for identifying properties internationally in a hierarchical manner starting with the country. Using the UPI, a property can be referenced in an unambiguous way, which is valuable for many use cases, including deduplication and globally unique references in different systems. The UPI works essentially by specifying a property’s “serial number” as a legally defined entity.

The next step for the UPI is developing a UPI Registry. This is an event-logging database that collects evidence of facts related to UPIs. For example, a company that sources data about property taxes or permits could produce a reference on the registry each time it registers a new fact about a UPI. This data producer wouldn’t put its full data in the registry, just a reference that it has facts about that UPI. As the number of data producers creating references to UPI facts grows, the confidence scores in the UPI Registry grow.
