Every number on this page belongs to a government agency or a program it funds, except the last section, which is our own phone line. We are a non-government website; checking an agency's own website for its current hours is always a good idea.

Other Arizona agencies
Insurance complaints: DIFI
The Arizona Department of Insurance and Financial Institutions regulates insurance companies and licenses insurance agents in Arizona. Consumer services: 602-364-2499.
