IDX – stands for Internet Data Exchange. This is a Broker advertising program. This program permits brokers who participate in the program to display each other’s Active, Contingent, Pending and Closed listings on their respective web sites.  Participation in the program is by office/firm. Active, Contingent, Pending and Closed listings of the participating firms are added to the IDX data base. Rules and policies spell out the standards to be met for an authorized IDX web site. Brokers/firms determine their own rules regarding requests for agent web sites displaying IDX listing data.  The Broker/firm must approve, manage and oversee the IDX web sites of their agents. Individual sellers may decline the option of displaying their property information on the Internet.

What is IDX?

IDX is all of the Participant’s listings that have opted in to the Internet Data Exchange program.

  • Your Firm does not have to have a web site to have your listings in the IDX program.
  • Unless you specify that you do not want to participate in IDX, your firm listings will go into the IDX data.
  • If your Firm has been a member of TMLS for more than 4 years, your Firm was grandfathered into the IDX program.

* Note:  listings that are marked Internet no will NOT be displayed in the IDX data.

Triangle MLS SmartFrame

Residential Sold Data Added to IDX

The Triangle MLS Directors have approved the addition of a limited amount of Residential Closed listing data for display on IDX web sites. Adding Closed data to IDX web sites is not a new concept. Many MLSs accross the country and in North Carolina (Triad and Charlotte) have changed their IDX rules permitting brokers/agents to enhance their web sites with sold data.

The brokers and agents of the Triangle MLS are the real estate experts in the greater Triangle area. Adding a limited amount of sold data to IDX sites increases the site's value to consumers and gives IDX web sites a competitive advantage over a lot of national sites. This additional information raises the level of conversation between the REALTOR® and the consumer. The Triangle MLS Directors' decision affects IDX sites only. Closed listing data will not be added to any other advertising portals.

The approved data is now available to vendors providing IDX web site solutions. This includes the Triangle MLS SmartFrame solution.
