Real estate agents use an MLS ID number to log in to the Multiple Listing System (MLS). The MLS ID number of a real estate agent is the same as a user name ID or login ID.
The Multiple Listing Service (MLS) is a network that connects real estate agents and brokers. This makes it easy for them to see what’s for sale. The service is used by real estate agents to help their buyers and sellers close deals in the same city, state, or around the world. The goal of the MLS is to make sure that compensation levels, like commissions, are the same and that agents can get specific information about properties, like square footage, number of rooms, amenities, and size.
