====New York City====
Although the other boroughs and Long Island have several different MLS{{Citation needed|date=July 2014}}, MLS has never taken hold in Manhattan.  A small group of brokers formed the Manhattan Association of Realtors and operate MLSManhattan.com.  MLSManhattan has a small fraction of the total active inventory in Manhattan.  The Bronx Manhattan North MLS also offers coverage in Northern Manhattan.  It too has failed to acquire widespread adoption by brokers.

The prevalent database is operated by the [[Real Estate Board of New York]] (REBNY), a non-Realtor entity that seceded from the National Association of Realtors in 1994.<ref>{{cite web|url=http://www.thefreelibrary.com/REBNY+pulls+out+of+NAR.+(Real+Estate+Board+of+New+York;+National...-a015774444 |title=REBNY pulls out of NAR |publisher=Thefreelibrary.com |access-date=2012-02-01}}</ref>  REBNY operates a database called RLS which stands for REBNY Listing Service.  A predecessor of RLS was marketed as R.O.L.E.X (REBNY Online Listing Exchange), before Rolex Watches claimed trademark infringement.

Like MLS, RLS has under contract, sold and days on market data, and houses rental listings as well.  There is a database, which in 2011, was slated to be converted to the more familiar RETS standard in January 2012. The RLS gateway is populated by several private databases that include RealtyMX (RMX), Online Residential (OLR) and Realplus, another proprietary database available to Manhattan Brokers.  These databases exchange data continually effectively creating several separate systems with essentially similar data.  Another vendor, Klickads, Inc D/B/A Brokers NYC, owned by Lala Wang sued in 2007 to be included in the list of firms permitted to participate in the Gateway.  REBNY also grandfathered the major brokerages including Douglas Elliman, Corcoran, Stribling, Bellmarc as participants to the Gateway.

Seriously committed Manhattan brokerages are members of REBNY, and thus one may find the vast majority of updated and valid listings in Manhattan are represented by RLS.  The REBNY RLS requires all listings to be entered and disseminated within 24 hours (Until 2007 72 Hours to accommodate agencies without weekend data entry).<ref>{{cite web |url=https://members.rebny.com/jsp/member/docs/manual/Residential_Resolution.pdf |title=Archived copy |access-date=2009-06-07 |url-status=dead |archive-url=https://web.archive.org/web/20110715162844/https://members.rebny.com/jsp/member/docs/manual/Residential_Resolution.pdf |archive-date=2011-07-15 }}</ref>
