Our Values


Our History

In early 1999, the National Association of REALTOR® (NAR) joined forces with leaders in the technology industry to explore ways to make access to MLS data easier for individual Realtors, as well as other third-party organizations.

By March of 2002, RESO was officially created as a working group in conjunction with NAR and soon presented its first version of the well-documented Real Standard Transaction Specifications (RETS).  RETS is a framework used by the real estate industry in the U.S. and Canada to facilitate the exchange of data.

RESO was officially incorporated in November 2011 as an independent, not-for-profit trade organization, and no longer part of the NAR.
