Certification
The RESO certification program provides the real estate industry’s seal of data excellence. Consumers want a technology experience where apps, servers, and other systems work together seamlessly and reliably. Certification ensures that MLSs have implemented RESO data standards and that brokers and technology partners are using the standards correctly. RESO certifies MLSs for RESO Data Dictionary compliance and certifies MLSs, brokers, and technology partners for RESO Web API compliance. | LEARN MORE
Certification is free as a RESO member benefit. Fees apply for nonmembers. | CERTIFICATION FEE SCHEDULE
Certification times vary based on the availability of access credentials and the amount of troubleshooting that is necessary. Please note that your organization is considered to be in compliance with NAR policy if you have an active application.
Organizations seeking certification can APPLY ONLINE. RESO reviews the application for current membership status and for a signed Declaration. If you do not have a signed Declaration, one will be sent to you via DocuSign. Certification is free to RESO members. If you are not a member and would rather pay for certification, your payment will need to be processed prior to the review process. RESO uses data access credentials supplied by the applicant and/or applicant’s technology vendor to run appropriate system tests. Certificates are suppled by RESO to those who pass the tests. Systems that do not initially pass testing are guided through troubleshooting by RESO staff before retesting.
A signed Declaration sent to support@reso.org is required by MLS organizations prior to certification to assure that certified companies continue to follow RESO standards after being certified. Its purpose is to protect the integrity of RESO certification by ensuring that companies that advertise RESO compliance remain compliant. | GET DECLARATION
A signed TMA allows members to display RESO logos on their website to show their commitment to standards and, in cases of certification, demonstrate to technology developers and brokerages that they can be relied upon to be interoperable with other tools. | GET TMA
While RESO certification is not mandatory, compliance to RESO standards is mandated for MLS systems that are owned and operated by REALTOR® associations. Becoming certified demonstrates that you are in compliance and that your system in interoperable with other tools. For other organizations, certification is voluntary but sends a strong signal that your company wants to be at the forefront of the industry’s best technology practices. The goal of certification is to bring the technology experience to real estate that consumers and professionals expect. | LEARN MORE
Yes, but not every year when you renew your annual RESO membership. Active certifications expire when the awarded certification is older than the two most recent versions of a specific standard. Certification on the most recent standard is classified as “Certified Current,” and certification on the previous most recent standard is classified as “Certified Legacy.” | LEARN MORE
RESO keeps a current list of MLSs that are either not certified or have not applied for certification. | VIEW LIST
No. Although a vendor may manage several MLSs, each MLS system is unique and must have its data setup and transport methodology certified. RESO uses MLS access credentials supplied by MLS vendors to verify standards conformance. When an MLS system passes testing, the vendor will reach out to a designated MLS staff representative to ask for results confirmation and an acceptance of certification terms. Once that is completed, certification from RESO is granted. | READ MORE
