Arizona Regional Multiple Listings Service (ARMLS®) was founded in 1982 and has grown to be one of the largest MLSs in the country.

ARMLS® is owned by three local associations: Phoenix REALTORS®, Scottsdale Area Association of REALTORS® and West and Southeast REALTORS® of the Valley (WeSERV). Our mission statement is “Provide the industry benchmark of quality data and service for our subscribers.” We strive to meet this by ensuring our subscribers have the most accurate and up-to-date MLS system and the best technology on the market. We strongly believe that ongoing training is important, both for new and seasoned agents. That’s why all education we provide to subscribers is free of charge. We offer online classes, webinars and office visits for your convenience.

Did you know that ARMLS® has over 42,000 subscribers. That includes:

  • 38,606 are Sales Agents

ARMLS® services over 3,200 offices in the Valley, spanning from Wickenburg to Casa Grande, Apache Junction to Tonopah. ARMLS doesn’t have a defined service area, but most of the lisings in the MLS can be found in Maricopa and northern Pinal County.
