Welcome to the Official Site for the World Wide MLS

The World Wide MLS is a global multiple listing service for everyone.

World Wide MLS (WWMLS) is an internet-based application offering:

  • An open system for posting, browsing and searching for real estate properties
  • A globally distributed network of Accredited OpenMLS® Registrars
  • A "level playing field" for real estate consumers, professionals, and businesses

WWMLS is comprised of two internet protocols, Multiple Listing Service Network (MLSN) Protocol and Real Estate Transport Protocol (RETP), invented by Corey Leong and governed by the Global Real Estate And Technology Consortium (GR8C), a nonprofit scientific organization. A messaging vocabulary, Real Estate Metadata Language, allows for sending and receiving listings between registrants, registrars, and the GR8C registry over the Internet.

WWMLS is a public service-based internet application for the benefit of all people throughout the world.
