IDX designs do not have any agent or office information included in the design. Unbranded deigns are used primarily when an MLS (Multiple Listing Service) specifies that branding and contact information cannot be included within a tour displayed through their service. IDX designs are also referred to as non-branded or unbranded.

What do IDX, VOX, and ILD mean?

According to the National Association of Realtors, ILD is an abbreviation for Internet Listing Display policy.

ILD consolidates and replaces both NAR's VOW policy and IDX policy to create a single, unified policy governing the Internet display of all property information originating from the 800+ MLSs owned and operated by REALTOR® organizations.

VOW and IDX are still in common usage.

VOW = Virtual Office Website. The primary distinguishing feature of a VOW is the requirement that visitors register by entering an e-mail address and receive a password prior to accessing MLS listing data.

IDX = Internet Data Exchange. IDX allows brokers to "advertise" each others' listings; the MLS data presented on an IDX Web site is typically less detailed, and viewers of the data remain anonymous.
