Data Share FAQ
Why is this data share being created?
We believe our members can better serve consumers, both buyers and sellers, with increased access to listing data. This data share makes MLS data from each of the participating MLSs available directly within the native MLS systems that our members work in each day.
How will I be able to search across the different MLS’s when each MLS has different field names and choices?
The data share is relying on the RESO Data Dictionary to standardize the MLS fields. The RESO Data Dictionary is a standard that ensures systems can speak the same language. It defines real estate data in consistent terms and structures. MLSs nationwide are moving to the RESO Standard to create efficiencies for our members and the technology partners who serve them.
What about our “local fields” that are unique to our MLS marketplace?
Each MLS has a short list of fields which are very unique to their local area. These fields will continue to be available in their respective native MLS system. It is important to note that searching on one or more of these “local fields” will exclude listings from the other MLSs as listings from the other MLSs will not contain data for the unique “local field” of another MLS.
Does this mean these MLSs are merging?
No. Each of the MLSs participating in this data share will continue to be separately owned entities. They will each continue to have their own Bylaws, Rules & Regulations and Policy Manuals. We are simply aligning our MLS Databases to allow our members to search across participating MLSs without leaving their native MLS system.
When do we expect this data share to be available?
Update: The Data Share went live on July 10, 2024.
Are other MLSs able to join this data sharing effort?
Now that the data share is live, other MLSs are welcome to consider joining the Coast 2 Coast MLS Data Share. It is an opportunity to partner with other MLSs to increase listing data access while maintaining your MLS’s identity and being allowed to continue to serve your local marketplace. Go to “Contact” in the menu for contact information of the participating MLSs’ CEOs for more information.
