The right number for what you need, and when someone will answer it. If you have just had an accident or something has happened at home, call claims. That line never closes.
By phone
Claims
Any hour, every day of the year. Report a new claim or reach the adjuster on an open one.
Member service and quotes
Weekdays 7am to 8pm, Saturdays 8am to 4pm. Policy changes, new quotes, documents.
Billing
Weekdays 7am to 8pm. Automated payments by phone any hour. How billing works.
Hours are Pacific time unless they say otherwise. Arizona does not change its clocks, so from March to November our Arizona office keeps the same hours as San Diego, and in winter it opens an hour earlier by the San Diego clock.
Spanish-speaking representatives are available on every line. For other languages, ask and we will bring an interpreter onto the call at no cost. If you are deaf or hard of hearing, dial 711 for the relay service and give them any of the numbers above.

Visit an office
Our head office in San Diego and our Arizona office in Phoenix have a front desk open weekdays from 8:30am to 4:30pm, local time. You do not need an appointment to drop off documents or make a payment, but for anything longer, call ahead and we will make sure the right person is there.
For a damaged car in the Inland Empire or Los Angeles County, the drive-in claims center at our Ontario office can photograph the damage and write an estimate while you wait. More about the Ontario center.
If you have a complaint
Start with the person you have been dealing with, or their supervisor. If that does not settle it, write to our member advocate at the head office address, marked "Member advocate". The advocate reports to the board rather than to the department you are complaining about, and will reply within 15 business days.
You can also contact the department of insurance in your state at any time. We will give you their contact details on request, and they are printed on your policy.
