Unique Identifiers

The ULI, which is still in development, is meant to provide all real estate licensees a unique ID number, whether or not they are affiliated with the National Association of REALTORS® (NAR). While NAR’s NRDS ID number is a critical cornerstone of identifiable information, it does not account for non-members. The ULI will attempt to bridge that gap within the U.S. as well as internationally.

The UOI (formerly OUID) provides organizations within the real estate industry a unique ID number. The UOI list includes a comprehensive list of REALTOR® associations, MLSs, real estate technology companies and other affiliated businesses and data providers. Having such a list at hand is useful for keeping track of unique business entities and their affiliations without including duplicate records. Companies are regularly edited and added to the list. | MORE INFORMATION
