If you are looking for the ACE Chubb auto insurance number, the primary contact for customer service and claims in 2026 is 1-800-252-4670. For specialized roadside assistance, policyholders should call 1-800-248-2201. Because ACE Limited acquired Chubb in 2016 and adopted the Chubb name globally, all legacy ACE auto policies are now managed through Chubb’s unified service infrastructure.
The transition from ACE to Chubb represents one of the largest mergers in the history of the insurance industry. While the "ACE" name may still appear on some internal documents or older policy forms, the consumer-facing entity is exclusively Chubb. This guide provides a deep dive into the various contact channels, claims procedures, and specialized service lines available to policyholders today.
Understanding the ACE and Chubb Integration
To understand why you might be searching for an "ACE Chubb" number, it is helpful to look at the corporate structure. In January 2016, ACE Limited completed its acquisition of The Chubb Corporation for approximately $29.5 billion. The resulting company decided to operate under the "Chubb" brand due to its high recognition in the personal lines and high-net-worth insurance markets.
In 2026, the integration is complete, meaning that whether you originally purchased a policy through ACE or are a new Chubb client, you use the same high-touch service network. Chubb is currently the world’s largest publicly traded property and casualty insurance company, known specifically for its "Masterpiece" auto preference, which caters to owners of luxury vehicles, classic cars, and multi-vehicle households.
Why the ACE Brand Still Appears
While the primary brand is Chubb, certain commercial divisions or international niche markets may still reference ACE in legal filings or specific reinsurance contracts. However, for a standard personal auto insurance policyholder, the phone numbers listed below are the correct points of entry for all inquiries.

How to File a Claim with Chubb (ACE)
Filing a claim with Chubb is a different experience than with many "standard" insurers. Chubb’s philosophy focuses on restoring the vehicle to its pre-loss condition using Original Equipment Manufacturer (OEM) parts, which is a significant differentiator.
Step 1: Immediate Safety and Documentation
Before calling the number, ensure all parties are safe. If there are injuries, call emergency services (911) first. Exchange information with other drivers, including names, phone numbers, insurance policy numbers, and license plate details. Use your smartphone to take high-resolution photos of the scene, the damage to all vehicles, and any relevant road signs or signals.
Step 2: Calling the Claims Number
When you call 1-800-252-4670, you will be connected with a claims specialist. Because of the ACE-Chubb merger, the system is designed to look up your policy by your Social Security Number, your Policy Number, or even your vehicle's VIN.
Information to have ready:
- Your policy number (found on your ID card or in the Chubb Mobile app).
- The date, time, and exact location of the incident.
- A description of the damage.
- The police report number (if applicable).
Step 3: The Appraisal Process
Chubb often employs its own adjusters who are trained in luxury and exotic vehicle repair. Unlike many insurers that might steer you toward a "preferred" budget repair shop, Chubb allows you to choose any repair shop you trust. If you do not have a preference, they can recommend a "Masterpiece Auto Preference" shop that meets their stringent quality standards.
Step 4: Rental Car and Loss of Use
If your policy includes "Loss of Use" coverage, Chubb provides one of the most generous rental car provisions in the industry. In many cases, there is no daily limit on the rental cost, allowing you to rent a vehicle comparable to the one being repaired, rather than a basic economy car.
Technical Advantages of Chubb Auto Policies
When you call the Chubb service number, you are accessing a suite of features that legacy ACE and standard policies often lack. Understanding these terms helps you communicate more effectively with your representative.
Agreed Value Coverage
Standard insurance policies typically pay "Actual Cash Value" (ACV), which factors in depreciation. If you have an Agreed Value policy with Chubb, you and the insurer agree on the vehicle's value at the start of the policy. If the car is totaled, that is the exact amount you receive, regardless of market depreciation. This is common for classic and high-end luxury vehicles.
OEM Parts Guarantee
When discussing repairs with a Chubb adjuster, you do not have to fight for Original Equipment Manufacturer (OEM) parts. Chubb’s policy language generally specifies the use of OEM parts rather than "aftermarket" or "like kind and quality" (LKQ) parts, ensuring the vehicle's structural integrity and resale value are maintained.
High Liability Limits
Policyholders often call the Chubb number to discuss "Umbrella" or "Excess Liability" integration. Because Chubb caters to high-net-worth individuals, they offer liability limits far exceeding the industry standard, often reaching $10 million to $50 million or more when combined with a personal umbrella policy.
Digital Alternatives: The Chubb Mobile App and Online Portal
While the "ACE Chubb auto insurance number" is the most direct way to get help, digital tools in 2026 have become highly sophisticated. The Chubb Mobile app is the preferred method for many users to manage their accounts without waiting on hold.
- Digital ID Cards: You can access your insurance cards even when offline.
- Direct Claim Uploads: You can upload photos of an accident directly to an open claim file, which speeds up the appraisal process.
- Bill Pay: Securely manage recurring payments via bank transfer or credit card.
- Agent Contact: The app stores your specific agent's contact information, which is often more useful than the general 800-number for nuanced policy advice.
International Support and Global Presence
Chubb operates in 54 countries. If you are a US policyholder traveling abroad or if you have an international policy (often a legacy of the ACE Global network), your contact method may change.
If you are in Europe, Asia, or Latin America, you should look for the local Chubb office number. However, for US-based clients traveling with their vehicles (e.g., into Canada or Mexico), the +1-302-476-6194 number serves as a global collect-call line for emergencies.
Troubleshooting Common Contact Issues
In some instances, callers may find it difficult to reach the correct department. This often happens if a policy is in a "grace period" or if the searcher is using an outdated ACE number from a document printed before 2016.
- Old Phone Numbers: Numbers like 1-800-433-0385 (an old ACE line) may still forward to Chubb, but it is more efficient to use the current 1-800-252-4670 number.
- Verification Failures: If the automated system cannot find your policy, stay on the line or press "0" to speak with a human operator. Have your VIN ready, as this is the most accurate way to locate a policy in the global database.
- Agent vs. Carrier: Chubb is an agent-based carrier. If you need a quote or a major policy rewrite, the corporate 800-number will likely refer you back to your independent agent. Use the "Find an Agent" tool on the Chubb website if you have lost your agent's contact details.
Frequently Asked Questions
What happened to the ACE auto insurance phone number?

Can I file a Chubb auto claim online instead of calling?

How do I contact Chubb for a classic car policy?
Classic and collector cars are usually handled through the same Masterpiece auto line at 1-800-252-4670. However, the claims process for these vehicles is specialized, focusing on "Agreed Value" payouts and specialized restoration shops. You should specify that the vehicle is a collector item when prompted by the automated system.

Final Recommendation
For the fastest service, always have your policy number and vehicle identification number (VIN) ready before calling. If you are involved in an accident, your first call should be to the claims line at 1-800-252-4670 to initiate the appraisal process immediately. For non-urgent matters, using the Chubb Mobile app is often more efficient than phone-based support, providing instant access to digital ID cards and policy documents.
