What Is an MLS (Multiple Listing Service)?
A Multiple Listing Service (MLS) is a private database that real estate agents use to share property listings with each other. Each MLS is operated regionally, and access is restricted to licensed agents who pay membership fees.
There are over 500 MLSs operating across the United States, each covering a specific geographic area. When a listing agent signs a seller, they enter the property into the local MLS so that buyer's agents can find it and bring offers.
Why the MLS matters for agent data
Every agent who lists or sells properties is registered with at least one MLS. This registration, combined with their state license, creates the data trail that makes agent contact databases possible. Companies that sell to agents — CRM vendors, coaching programs, mortgage lenders — use agent databases built from MLS and licensing records to reach their target market.
Key facts about the MLS
- Access requires a real estate license and association membership - Most MLSs charge monthly or annual fees ($20-60/month is typical) - The NAR (National Association of Realtors) oversees MLS standards through its subsidiary, the Real Estate Standards Organization (RESO) - Recent legal settlements (Sitzer/Burnett) are changing how commissions are displayed in MLS systems
