Internet Data Exchange


Internet Data Exchange (IDX) is a system where Participants give each other permission to display their listings on each others’ web sites. The advantages of IDX are:

  • Participants become empowered to deal with the real estate consumer of the future.
  • Participants can fully market their services on the Internet.
  • Participants can take advantage of the data brokers have contributed to the system.
  • Participants can obtain and maintain first contact with the consumer in the real estate transaction.
  • Consumers will stay longer when they visit Participants’ web sites because they offer more listing data.

NAR’s Board of Directors made reciprocal Internet Data Exchange a mandatory policy effective Jan. 1, 2002 to encourage uniform Internet listing opportunities for all REALTORS®. Display of Information is subject to the rules of the NJMLS and NJREC. Licensing Agreement required.
