The nation’s largest MLS, CRMLS, which serves over 108,000 subscribers in California, updated its policy in September to require all brokers to prominently display the name and contact info of listing brokers and agents on listings they receive through an IDX feed. Instead of appearing down on listing display pages, brokers must now display that information toward the top. Now that Zillow Group displays listings on its site as a participating broker through IDX feeds, rules like this carry more weight, especially from the nation’s largest MLS. Many portals, including realtor.com, now prominently display listing broker or agent names and contact info. CoStar Group has said it plans to compete by leaning into the industry’s Fair Display Guidelines, of which prominent listing broker or agent display is key component.
