21st Century is a California-only auto insurer and part of the Farmers Insurance Group of Companies. Its own site says coverage “is currently only available in California,” and the policies are underwritten by 21st Century Casualty Company. If you’re an existing policyholder, the fastest way to get help is usually phone support or your online account.

21st Century offers standard California auto insurance options, plus a variety of ways to save through discounts (see our guide to 21st Century auto insurance discounts). If you need an SR-22 or you’re insuring a classic or collector car, ask the sales line what 21st Century will write before you shop. Its site doesn’t list a collector car product.

The company has been around since 1958, according to its Better Business Bureau listing. Here’s how to reach the right department quickly.

1. Use The Right Department: Policy service, claims, roadside, and sales each have different numbers—calling the correct line saves time.
2. Claims And Roadside Are 24/7: 21st Century prints “Available 24 hours a day, 7 days a week” next to the claims number, and the roadside program runs 24/7. Customer service is Monday to Friday only.
3. Online Accounts Handle Most Tasks: Payments, ID cards, document access, and many policy changes can often be completed through your 21st.com login.
4. Escalation Is Available: If you can’t resolve an issue, California drivers can contact the California Department of Insurance for questions or complaints.

21st Century Customer Service Contact Information

You can also manage many tasks online through the 21st Century “Contact Us” and login area: Manage your policy online.

Every number above comes off a 21st Century page. The policy service, claims and roadside numbers are on its Contact Us page; the sales number is on its contact a representative page. If a number ever stops working, use the one printed on your ID card or your policy documents.

Does 21st Century Have 24/7 Customer Service?

Some departments are available 24/7, while general policy servicing is typically limited to business hours. In general:

• Claims: 21st Century prints “Available 24 hours a day, 7 days a week” beside the claims number.
• Roadside assistance: 21st Century calls this “24-Hour Roadside Assistance” on its roadside page and says it is “available to you 24/7.”
• Policy service and billing: live representatives Monday to Friday, 8:00 a.m. to 6:00 p.m. Pacific. 21st Century doesn’t publish weekend service hours. Its website and automated phone system stay open, which is not the same as reaching a person.

What Are 21st Century’s Customer Service Hours?

21st Century publishes one set of service hours and leaves the rest vague. Here is what it actually prints. If you’re calling outside these windows, use your online account or the claims and roadside lines, which run around the clock.

One thing to keep straight when you read those hours. 21st Century says its website and its automated phone system are available “24 hours a day, 7 days a week,” and that is the part that never closes. Live representatives are a different matter. The only clock hours it publishes for them are Monday to Friday 8:00 a.m. to 6:00 p.m. Pacific for customer service, and for sales it says only “Monday to Saturday during regular business hours” without naming a time. The 24/7 labels on claims and roadside are 21st Century’s own words, and it doesn’t say how many of those hours have a person on the line.

Note: Hours can change, so check the contact page before you plan a call. 21st Century is a Farmers company and your policy is underwritten by 21st Century Casualty Company, but the numbers above are the 21st Century lines, not the Farmers ones. If you had a Toggle policy, 21st Century is moving those policies onto 21st Century branding and sends new documents about 30 to 45 days before renewal.

How Do You File a Claim With 21st Century?

To file a claim, the most reliable option is to call the 24/7 claims line at 1-888-244-6163. 21st Century also offers an online claims portal, but if the portal doesn’t load correctly on your device, the phone line is the fastest fallback.

How Do You Get Roadside Assistance?

For roadside help, call 1-800-439-5587 24/7. 21st Century says policyholders are automatically enrolled in its roadside program for each insured car at no extra cost, and that services are provided by or through Cross Country Motor Club of California, Inc. Two limits are worth knowing before you call: coverage runs to $75 per service, and you get five service calls per vehicle per calendar year. 21st Century publishes no towing mileage limit, so the $75 is the real cap.

Mailing Addresses for Claims and General Inquiries

If you need to mail documents, 21st Century lists these addresses on its own mailing address page. Payments, policy letters and claim documents each go somewhere different, so check the row before you send anything. Keep copies and use tracking for time-sensitive items.

If You Need to Escalate a Problem

If you can’t resolve an issue through customer service (for example, delays, cancellations, or claim handling concerns), California drivers can also ask questions or file a complaint through the California Department of Insurance. Start here: California Department of Insurance: Getting Help. The department’s consumer hotline is 1-800-927-4357. It doesn’t publish hours for that line. Rules and processes vary by state.

Final Word

To contact 21st Century customer service, the best starting point is usually policy service at 1-800-241-1188. For urgent needs, remember the 24/7 lines: claims at 1-888-244-6163 and roadside assistance at 1-800-439-5587. When in doubt, your online account can handle many routine requests without waiting on hold. My advice is to save the claims and roadside numbers in your phone now, under the insurer’s name, because the moment you need them you won’t want to be hunting for a card in the glovebox.
