Yes, an active Costco membership is mandatory to purchase or maintain a Costco car policy. This insurance program is a membership benefit administered through CONNECT, powered by American Family Insurance. You cannot finalize a purchase without a valid membership number. While non-members might obtain an online quote for comparison, it serves only as a preview; actual policy issuance requires membership verification.
The requirement is tied to Costco's business model, which centers on providing value to its members. The insurance program is structured as a member-exclusive perk, often featuring competitive rates and additional discounts not available to the general public. This exclusivity is a key differentiator in the market.
Two primary membership tiers qualify for this benefit: the Gold Star Membership and the Executive Membership. The cost and benefits of these tiers directly influence the insurance offering.
| Membership Type | Annual Fee | Core Insurance Access | Additional Potential Benefits |
|---|---|---|---|
| Gold Star | $65 | Yes, full policy purchase | Standard member discounts. |
| Executive | $130 | Yes, full policy purchase | Enhanced discounts, possible added benefits like roadside assistance. |
The process typically involves getting a quote on the CONNECT/Costco Insurance Services website. You may initially enter details without a membership number to see estimated rates. However, to proceed beyond the quote, you must provide an active membership number for verification. Policy management, including renewals and claims, is also contingent on maintaining an active membership status.
Geographic availability is a crucial consideration. Costco car insurance is not offered in every state. As of the latest market data, coverage is available in a majority of states, but notable exceptions include Massachusetts, Michigan, and New Jersey. Availability can change, so verifying eligibility for your specific state zip code is an essential first step.
The value proposition for members is significant. Industry analyses of bundled member benefits often highlight the insurance program. Reports suggest that members who bundle auto insurance with other Costco services, like home insurance, may access additional savings. The program's structure, with CONNECT as the underwriter, is designed to leverage group buying power, which can translate to lower premiums for eligible members compared to standard market rates.

















As someone who shops at Costco regularly, I looked into this. The bottom line is you absolutely need to be a paid member. I tried getting a quote online out of curiosity—it let me put in my info, but then it hit a hard stop asking for my membership number. No number, no . It’s like the discounted rotisserie chicken or the food court; it’s strictly for cardholders. If you’re not a member, this option isn’t on the table for you at all.

Let me you through exactly how this works from my experience. I’m an Executive member, and I switched my policy over last year.
First, I went online to the Costco insurance page. You can plug in your details—car model, driving history, zip code—and get a price estimate without your membership number. That’s useful for a quick comparison. But that’s all it is: an estimate.
When I decided to move forward, the system prompted me for my membership number. It verified it was active and in good standing. Only then could I see the final, official rate and complete the application. The whole process was handled through CONNECT, which is Costco’s insurance partner.
The membership requirement isn’t just a formality. My Executive membership fee gets me an extra discount on top of the base member rate. They also rolled roadside assistance into my policy automatically, which was a nice perk. Just remember, if your membership lapses, your insurance eligibility likely does too.

Think of it as a locked benefit. The is part of the package you pay for with your annual membership fee.
Key points:
State restrictions apply. This program isn’t available nationwide. Major states like Massachusetts and Michigan are currently excluded. Always check availability in your specific state before counting on it as an option.
The underwriter is CONNECT, a subsidiary of American Family Insurance, which provides the actual insurance coverage. Costco essentially brokers the group discount for its members.

Evaluating this requires a cost-benefit analysis. The $65 annual Gold Star membership is a mandatory upfront cost. You must factor this into any savings calculation.
The potential value lies in the member-exclusive pricing model. Because the program is designed for a specific group (Costco members), the risk pool and operational costs are managed differently, which can result in lower premiums. Market observations indicate that for safe drivers and those willing to bundle policies, the total annual savings on insurance can potentially exceed the membership fee, making the program financially sensible.
However, it’s not an automatic win. You must get a personalized quote. The membership is your ticket to the real price. Without it, you’re only window-shopping. Furthermore, the program’s competitiveness can vary by state, driver profile, and vehicle type. It’s a compelling option for existing members, but for non-members, the decision hinges on whether the projected insurance savings justify the new, recurring cost of a membership.
