RESO certifies systems to ensure they comply with real estate data standards. A RESO certification is a badge of honor for a system which technology developers and brokerages can rely upon to be interoperable with other tools.
The goal of certification is to bring a technology experience to real estate that consumers and professionals expect. Consumers demand a smartphone experience where apps, servers, and any other systems can talk to one another and operate seamlessly together. Standards provide that common language.
RESO Certification Quick Facts:
- RESO is currently certifying on Web API 1.0.2 and Data Dictionary 1.6.
- RESO classifies certifications on the two most recent versions of a standard as “Active”.
- The National Association of REALTORS® requires REALTOR® operated MLSs to be in compliance with new RESO standards within 12 months of RESO ratification.
- Certification isn’t just for MLSs. Brokers and technology vendors with Web API servers are also certifying with RESO.

The Certification Process
- Application and verification: Organizations seeking certification apply through the RESO website. RESO reviews the application for current membership status, a current signed Trademark Agreement and a signed Declaration (available here).
- Compliance testing: RESO uses access credentials supplied by the applicant and/or applicant’s technology vendor and runs the appropriate tests for the system.
- Certification or troubleshooting: Applicants whose systems pass testing are provided with certificates from RESO. Systems which do not initially pass testing are guided through troubleshooting by RESO staff. Systems are retested for certification.
