Announcing Bay Area Cooperative Key Reciprocal Access Agreement


BAREIS MLS® is pleased to announce the conclusion of three years of negotiations with seven Northern California Multiple Listing Services and their sixteen affiliated Association of REALTOR® organizations in and around the Bay Area that participate in our Northern California Data Share Agreements to establish a cooperative key program in Northern California.
Effective January 9, 2012, you have the ability to receive a cooperative code for your Supra Key from a number of other MLS’s that will honor your BAREIS MLS® membership.  In order to qualify you must maintain your BAREIS MLS® membership, and be a Supra Key holder in good standing.  You will then be able to cooperate your existing BAREIS MLS® key for a cooperative fee to access properties in other MLSs without the requirement of joining the other participating MLSs or Associations issuing the cooperative code.
  • Cooperating your key at any one of the following MLS’s or at their Associations/Service Centers will grant you lockbox access at all of them:
    • San Francisco Association of REALTORS® MLS
    • Contra Costa Association of REALTORS® MLS
    • Bay East Association of REALTORS® MLS
    • EBRDI
    • MLSListings®
  • Procedures for cooperating your key at MetroList® remain the same as it has in the past and grants you lockbox access in all areas covered by their MLS.
  • BAREIS members may also cooperate their keys with Sutter-Yuba Association of Realtors® MLS.
More information regarding participating Associations and MLSs where you can cooperate your key is posted at
