Welcome to the Massachusetts Office of Consumer Affairs and Business Regulation (OCABR).

At OCABR, we and our five agencies work together to achieve two goals: to protect and empower consumers through advocacy and education, and to ensure a fair playing field for all Massachusetts businesses.

We have designed our website to bring our most valuable information right to your fingertips. With a few easy clicks, check if your car qualifies as a “lemon,” see if a contractor is properly licensed, or access our many other consumer and business resources. If our site cannot answer your question, please call one of our Consumer Information Specialists at (888) 283-3757 or (617) 973-8787 weekdays from 9 a.m. to 4:30 p.m.  You can also email us a question or complain by clicking here .

Again, Welcome!

Barbara Anthony, Undersecretary
