Costco does not sell car insurance directly, but it offers discounted rates through partner insurers
Costco itself does not underwrite or issue car insurance policies. Instead, the warehouse offers discounted rates on auto insurance through partnerships with established insurance companies. Members can access these discounts by visiting Costco's insurance services page or calling the number listed in their membership materials. The partner insurers vary by state, so the companies available to you depend on where you live.
The discount typically applies to the base premium — the price before any other discounts the insurer offers. Costco members often report savings of 10 to 15 percent compared to the same policy purchased directly from the insurer, though the actual savings depend on your driving history, location, and coverage choices. The insurance itself is underwritten and serviced by the partner company, not by Costco, so claims and customer service go through the insurance company's normal channels.
Key Takeaways
- Costco partners with insurance companies to offer member discounts, but does not sell insurance itself.
- The partner insurers available to you depend on your state; not all companies operate in all states.
- Discounts typically range from 10 to 15 percent off the base premium, though your actual savings depend on your profile and location.
- You can compare Costco's discounted rates against quotes from other insurers before deciding, since the lowest price is not always the best value.
Which insurance companies partner with Costco
Costco's insurance partners include major national carriers such as Amica Mutual, Infinity, National General, and others, but the specific companies available to you depend on your state. Some states have only one or two partner options, while others have more. You can see which insurers serve your area by entering your zip code on Costco's insurance page or by calling their insurance services line.
Each partner company has its own underwriting standards, claims process, and customer service setup. The Costco discount is a negotiated rate reduction, but the policy terms, coverage options, and claims handling are controlled by the insurance company, not by Costco. This means your experience with the insurer matters as much as the discount itself.
How to get a Costco car insurance discount
To see what rates Costco's partners can offer you, visit the insurance services section of Costco.com or call the number provided in your membership materials. You will need basic information: your driver's license number, vehicle identification number (VIN), current coverage details if you have insurance, and driving history. The process is the same as getting a quote from any insurer — you provide information, and the company calculates a rate based on their underwriting rules.
Once you receive a quote, you can purchase the policy directly through Costco's partner portal or by phone. The discount is built into the quoted rate, so you do not need a separate coupon or code. If you decide to buy, the policy begins on the date you choose, and you will receive policy documents and billing information from the insurance company, not from Costco.
Comparing Costco rates to other insurers
A Costco discount is worth exploring, but it should not be your only quote. Insurance rates vary widely based on the company's underwriting model, so one insurer's price for your profile may be significantly lower or higher than another's. Getting quotes from at least two or three other major insurers — such as State Farm, Geico, Progressive, or Allstate — takes 15 to 20 minutes and can reveal whether Costco's partner is truly offering the best rate for you.
When comparing quotes, make sure each one covers the same liability limits, deductibles, and optional coverages. A quote that looks cheaper because it has a higher deductible or lower liability limits is not a true comparison. Also check whether each company offers discounts you may have access to for — bundling home and auto insurance, good driver discounts, or safety feature discounts — because these can shift which insurer ends up cheapest.
What coverage options are available through Costco partners
Costco's partner insurers offer standard auto insurance coverage: liability (bodily injury and property damage), collision, comprehensive, uninsured motorist, and medical payments. You can choose your deductible, liability limits, and optional add-ons the same way you would with any insurer. The Costco discount applies to the base rate, but you still control what coverage you buy and how much you pay for it.
Some partner companies offer additional options like roadside assistance, rental car reimbursement, or accident forgiveness, though availability varies by state and company. Ask the insurer or Costco's insurance services line what add-ons are available in your state before you buy, so you know what options exist.
When Costco insurance may not be the best choice
If you have a complex driving history — multiple accidents, violations, or a suspended license — some of Costco's partner insurers may decline to cover you or offer only high-risk rates. In those cases, a company that specializes in high-risk drivers might be your only option, even if the rate is higher. Similarly, if you need coverage that a partner insurer does not offer in your state, you will have to go elsewhere.
Costco's partners are also not always the best fit if you value a specific company's customer service, mobile app, or claims process. Some people prefer working with a local independent agent, which Costco's online and phone-based model does not provide. The discount is real, but it only matters if the insurer can actually cover you and if you are comfortable with how they do business.
How Costco's discount compares to other membership programs
Other membership programs and organizations — AAA, AARP, alumni associations, employer groups — also negotiate discounts with insurers. These discounts typically range from 5 to 15 percent, similar to what Costco offers. The actual savings depend on which insurer is offering the discount and what your profile looks like. A Costco member might save more through an AAA discount with one company, or vice versa, depending on how each insurer prices your risk.
If you belong to multiple organizations that offer insurance discounts, it is worth getting quotes through each one. The insurer and the discount level matter more than the source of the discount. Costco's advantage is convenience if you are already a member and shopping there, but the financial advantage is not automatic.
Frequently Asked Questions
Can I buy car insurance at a Costco warehouse location?
No. Costco's insurance services are available only online through Costco.com or by phone. You cannot purchase a policy in person at a warehouse. The insurance is underwritten by partner companies, not by Costco itself.
Do I have to be a Costco member to get the discount?
Yes. Only active Costco members can access the discounted rates through Costco's insurance partners. If your membership lapses, you lose access to the discount, though you can renew your membership and regain access.
What happens to my policy if I cancel my Costco membership?
Your insurance policy continues. The discount was applied when you bought the policy, but canceling your membership does not cancel your insurance or remove the discount retroactively. If you renew or change your policy later, you would need an active membership to access Costco's discounted rates again.
Can I switch to a Costco partner insurer if I already have car insurance?
Yes. You can get a quote from a Costco partner at any time and switch to them if the rate is better. Make sure the new policy start date is set for after your current policy ends, so you do not have overlapping coverage or a gap in coverage.
Are Costco's partner insurers legitimate and regulated?
Yes. All of Costco's insurance partners are licensed insurers regulated by state insurance departments. They must meet the same financial and operational standards as any other insurer. The Costco discount is simply a negotiated rate; it does not change the insurer's legitimacy or the coverage you receive.
