GLS – The Global Listing Service ®

Visit Wikipedia, the free encyclopedia

GLS GLS is an acronym used to denote the Global Listing Service for real estate.

The marketing of real property, including land for sale, houses for sale, homes for sale, rental, lease, commercial, investment, development, income and all properties for sale are aggregated for marketing and cooperative commission purposes (co-op).

The GLS is the combined listing service, which includes all properties for sale worldwide. Look for the GLS Logo when searching real estate.

Global Listing Service

Primarily in the United States real estate market, but also with International real estate (including Europe and other countries) there are separate aggregate listing databases for real estate and properties of all types: for sale, rent, lease and exchange.

Additionally, there exist differing attempts at forming a National MLS system (national listing service), consisting primarily of property data aggregated from existing MLS systems and other REALTOR® sources.

The GLS differs from these listing databases in that it is an inclusive, rather than exclusive dataset. This approach allows for a much more viable marketing solution by providing more and relevant real property data records, in response to current consumer and marketing demands worldwide. The GLS is also an open system, as opposed to being controlled by any national or international real estate organization, such as NAR, allowing both flexibility and cost efficiencies not present in closed systems.

The GLS includes Land, Agricultural, Development, Homes, New Construction, Income, Multi-Family, Foreclosure, Pre-foreclosure, Bank-Owned, REALTOR® listed, FSBO (For Sale By Owner), Rental, Lease, Apartment, Condo, Time-Share, Vacation, Commercial and any other types of real property listed worldwide with the Global Listing Service.

Inclusion in the GLS for real property listings is non-compulsory and is currently offered as a free service. Properties may be added to the GLS directly via the online real estate portal and system tools available at, Inc. Property upload options include manual, bulk, and automated data upload. Specifications and requirements are available here.

The GLS designation assures that the full property information is gathered, presented and distributed in a standardized format. Similar examples are present in the Real Estate industry worldwide, including: MLS, IDX, VOW, ILD, RETS and other standards.

The Global Listing Service

The Global Listing Service goes beyond the previous standards by encompassing all property and data types and feeds into a single aggregated source. Brokers, portals, agents, websites and other parties may display or utilize the GLS data via licensing agreement(s).

REALTOR®, Broker/Agent, and MLS listings typically represent only a subset of the GLS data, although many MLS Boards and MLS System Providers are licensing GLS data to provide to their REALTORS® and real estate buyers and sellers.

The Real Estate industry traditionally has worked to protect the co-op payments to real estate agents and brokers by strict control of the property data. This approach is less effective in today’s global real estate market where an international viewership and buyer/seller base now seeks real property info, homes for sale and more in a single source or destination website.

The Global Listing Service properties data feed permits real estate professionals to present the full global property suite: for sale, rent/lease, and exchange listings directly from their REALTOR®, Agent, Broker or Lender web page and website(s).

The GLS was developed as a standard for the global real estate and real property industry worldwide. Read more about Real Estate and Database Aggregators.
