Where Is Mercury Insurance Headquarters?
Mercury’s corporate structure can make the headquarters question confusing because current official sources identify two important California locations.
Mercury General Corporation Corporate Headquarters:
4484 Wilshire Boulevard
Los Angeles, CA 90010
USA
Mercury General Corporation’s current SEC filings and corporate materials identify the Wilshire Boulevard location as the company’s principal executive and corporate headquarters.
Mercury Insurance’s consumer-facing company information also describes Mercury as headquartered in Brea, California, and its Contact page lists:
Mercury Insurance
555 W. Imperial Hwy.
Brea, CA 92821-4802
USA
For a CorporateOfficeHeadquarters.com listing, 4484 Wilshire Boulevard remains the appropriate corporate headquarters for Mercury General Corporation, while the Brea address is useful for customers seeking Mercury Insurance’s current consumer-contact operation.
What Is the Mercury Insurance Corporate Phone Number?
The current Mercury General Corporation corporate-office phone number is 323-937-1060.
This number appears with the Los Angeles headquarters in current Mercury corporate materials and SEC filings.
The corporate number should not be confused with Mercury’s primary customer-service and claims number. Policyholders and claimants should generally call 1-800-503-3724 instead.
Mercury Insurance Customer Service
Mercury Insurance Customer Service can be reached at 1-800-503-3724.
Mercury uses this number for a variety of customer needs, including:
- Policy questions
- Billing and payment assistance
- Coverage questions
- Claims
- Account assistance
- General customer-service concerns
Mercury’s Contact page also provides an online message option for general questions that are not related to a specific policy or coverage issue.
For policy changes, customers can also contact their Mercury agent or sign in to their online account.
Mercury Insurance Claims Phone Number
Mercury’s claims hotline is 1-800-503-3724.
Auto and property claims can be reported 24 hours a day, seven days a week. Mercury also provides an online claims system for reporting and managing eligible claims.
When reporting a claim, have relevant information available privately, which may include:
- Policy number
- Date and location of the loss
- Description of what occurred
- Photographs or other documentation
- Police or incident-report information when applicable
- Other parties involved
- Repair or property-damage information
Do not post policy or claim numbers publicly when seeking help with a Mercury complaint.
Mercury Auto and Property Claims
Mercury handles automobile and property claims through its central claims operation. A customer who has already filed a claim should generally work with the assigned claims representative before attempting a corporate escalation.
If there is a disagreement about a claim, document:
- The claim date and claim number
- Names or departments of representatives contacted
- Repair estimates or contractor estimates
- Photographs
- Letters or emails from Mercury
- Payments already issued
- Items that remain disputed
- The specific resolution requested
Ask for a claims supervisor or manager if the assigned representative cannot resolve an issue or explain the company’s position.
Mercury Insurance Billing and Payments
Mercury customers with a billing or payment question can call 1-800-503-3724.
Current billing-support hours are Monday through Saturday from 5 a.m. to 9 p.m. Pacific Time.
Mercury also provides online payment and account-management options. Customers may be able to make payments online, by phone, through MoneyGram or by other methods available for their policy.
A policyholder disputing a cancellation, late payment, autopay transaction or billing amount should contact Mercury promptly because insurance policies can be subject to specific payment and cancellation deadlines.
Mercury Insurance Customer Mailing Address
Mercury’s current Contact page lists the following customer-contact address:
Mercury Insurance
555 W. Imperial Hwy.
Brea, CA 92821-4802
USA
This Brea address is more appropriate for ordinary customer-contact purposes than assuming that every insurance matter should be mailed to the Los Angeles corporate headquarters.
Customers sending a payment, claim document or other time-sensitive material should confirm the correct address on their policy documents or with Mercury first because specialized departments can use different mailing addresses.
How to Escalate a Mercury Insurance Complaint
Insurance complaints are usually most effective when the customer first gives the appropriate Mercury department an opportunity to resolve the problem.
- Contact the correct department: Call 1-800-503-3724 for customer service, billing or claims.
- Contact the assigned agent or claims representative: An existing agent or adjuster may be able to resolve policy-specific or claim-specific questions.
- Document the problem: Keep policy documents, claim correspondence, estimates, photographs, bills and payment records.
- Request supervisor review: If the initial representative cannot resolve the matter, ask for the appropriate supervisor or manager.
- Keep a timeline: Record dates of calls, names or departments contacted, promised callbacks and written responses.
- State the requested resolution: Explain clearly whether you are seeking a payment review, claim decision, billing correction, reinstatement, written explanation or another specific outcome.
- Use the corporate route when appropriate: Unresolved corporate correspondence can be directed to Mercury General Corporation, 4484 Wilshire Boulevard, Los Angeles, CA 90010.
- Contact your state insurance regulator when appropriate: Insurance companies are regulated at the state level, and consumers can file complaints with the insurance department in the state where the policy was issued.
The NAIC State Insurance Department directory can help customers locate the appropriate regulator.
California Mercury Insurance Complaints
Mercury is headquartered in California and writes substantial insurance business in the state. California consumers with an unresolved claim, cancellation, nonrenewal, underwriting or other insurance-company complaint can contact the California Department of Insurance.
- California Department of Insurance Consumer Hotline: 1-800-927-4357 / 1-800-927-HELP
- Consumer Help: California Department of Insurance Consumer Help
