About Metropolitan Regional Info System
Metropolitan Regional Info System (MRIS) was the four-letter word of Washington DC real estate for a quarter century, the system agents from Baltimore to Fredericksburg logged into every morning. Searches for MRIS IDX still happen daily, and the practical answer is that the data now flows through Bright MLS, its successor. If you came here wanting Metropolitan Regional Info System IDX on your website, you will leave with a Bright feed, and your visitors will never know the difference.
The MRIS story:
- Founded in 1993 by merging the listing systems of Baltimore-area REALTOR associations with those of surrounding jurisdictions
- Headquartered in Rockville, Maryland
- Grew into the largest MLS in North America during the 2010s
- Core territory: Washington DC, Maryland, and Northern Virginia, with reach into parts of Pennsylvania, Delaware, and West Virginia
- An early adopter of computer-based listing databases back when fax machines ruled the industry
- Joined with TREND and seven other regional systems to launch Bright MLS in 2017, with subscribers fully converted by 2018
The name retired; the coverage never blinked. Two decades of MRIS listing history rode along into Bright's database.
Coverage area
Coverage today runs through Bright MLS, the successor system, across:
- Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, Washington DC, and West Virginia
The historical MRIS heartland within that footprint:
- Washington DC: every quadrant of the District
- Montgomery and Prince George's counties: Bethesda, Silver Spring, Rockville, and Bowie
- Baltimore metro: the city plus Baltimore County, Howard, Anne Arundel, and Harford
- Northern Virginia: Fairfax, Arlington, Alexandria, Loudoun, and Prince William
- The commuter fringe: Frederick, the West Virginia Eastern Panhandle, and south-central Pennsylvania
Agents in these markets were MRIS subscribers longer than anywhere else, and they remain the deepest-coverage areas in the successor system.
How to get Metropolitan Regional Info System listings on your website
The MRIS application process retired with the merger. Everything now runs through Bright, and CloseDaily sits on the vendor side of that relationship:
- Hold an active Bright membership. MRIS memberships became Bright memberships during the conversion, and new agents join Bright through a member association.
- Submit Bright's IDX application. Your broker or office signs off, and Bright allows 14 days for that approval before the application expires.
- CloseDaily provisions the feed. We work from an established Bright data relationship over its RESO Web API, so there is no cold-start on the vendor end.
- CloseDaily launches search on your domain. Field mapping, display rules, listing pages, and alerts are our work, not yours.
Anything MRIS-branded in your files, IDX agreements included, was superseded during the merger. Expect fresh Bright paperwork rather than a renewal of the old documents.
CloseDaily and Metropolitan Regional Info System
CloseDaily supports IDX integration for Metropolitan Regional Info System, delivered today through its successor, Bright MLS. Your site gets the DC, Maryland, and Northern Virginia inventory MRIS was famous for, with CRM, lead capture, and follow-up in the same platform.
This region's buyers are relentless researchers, comparing commutes on two beltways and school districts in three jurisdictions. A site with full regional search keeps them researching with you rather than drifting to a portal.
Pricing opens at $299 per month, with a credit card required for the 7-day free trial. Onboarding covers the feed work, typically a few business days after Bright approves the IDX application.

Frequently asked questions
Does CloseDaily support Metropolitan Regional Info System IDX?
Yes. CloseDaily supports IDX integration for Metropolitan Regional Info System through Bright MLS, where MRIS data and membership have lived since the merger. We provision and launch the feed during onboarding.
How do I add Metropolitan Regional Info System home search to my website?
Submit an IDX application with Bright, get your office's sign-off within the 14-day window, and CloseDaily handles the rest through our existing Bright relationship. The MRIS name will not appear on any of the paperwork.
What areas does Metropolitan Regional Info System cover?
MRIS's historical core was Washington DC, Maryland, and Northern Virginia, with reach into Pennsylvania, Delaware, and West Virginia. Through Bright, today's coverage spans eight states plus DC across the Mid-Atlantic.
How long does Metropolitan Regional Info System IDX setup take?
Bright's IDX approval, including the 14-day office sign-off window, sets the pace. CloseDaily's feed work happens during onboarding and typically wraps in a few business days once approval lands.
Is MRIS still active?
Not as a standalone system. MRIS merged into Bright MLS in 2017 and its subscribers finished converting in 2018, so the organization lives on inside Bright. Our Bright MLS page covers the current system in full.
I still have MRIS login credentials and paperwork. Are they worth anything?
The logins went dark with the 2018 conversion, and MRIS-era data agreements were superseded by Bright's. Your membership carried over, though, so getting current is a paperwork refresh, not a new membership.
