Costco does not accept WIC vouchers or cards at any of its locations

Costco is not an authorized WIC vendor in any state. You cannot use WIC benefits to pay for groceries at Costco, even if you have a membership. WIC programs maintain their own lists of approved retailers, and Costco does not appear on any of them.

This is true across all 50 states and U.S. territories where WIC operates. The restriction applies to all Costco locations — warehouse clubs are simply not part of the WIC vendor network. If you shop at Costco with your own money, you can buy WIC-approved foods there, but you cannot use your WIC card or vouchers to pay.

Key Takeaways

  • Costco does not accept WIC cards or vouchers at any location in any state.
  • Warehouse clubs like Costco, Sam's Club, and BJ's Wholesale are not authorized WIC retailers.
  • Your state WIC program publishes a list of approved stores where you can use your benefits.
  • Most WIC-authorized stores are supermarkets, grocery chains, and independent grocers, not membership clubs.

Why warehouse clubs are not WIC vendors

WIC programs require vendors to meet specific operational standards: they must stock a defined set of approved foods, allow WIC staff to conduct audits, accept the state's WIC payment system, and maintain records of WIC transactions. Warehouse clubs like Costco operate on a membership model and do not meet these requirements.

Costco's bulk-sale format also conflicts with WIC's food package structure. WIC provides specific quantities of items — for example, one gallon of milk per month or 16 ounces of cheese. Costco typically sells items in larger bulk quantities that do not align with WIC package sizes. The store's membership requirement is another barrier; WIC programs do not reimburse membership fees, and requiring one would create an additional cost for WIC participants.

How to find stores that do accept WIC in your area

Your state WIC program maintains an official list of authorized retailers. You can find this list by contacting your state WIC agency directly or visiting your state's WIC website. The list is usually searchable by zip code or city, and it shows which stores near you accept WIC.

You can also call 211 (a free helpline) and ask for the WIC vendor list in your area. Many states also print the list on the back of your WIC card or include it in your welcome packet when you first receive benefits. The list changes periodically as stores join or leave the program, so check it before you shop if you are visiting a new location.

What types of stores typically accept WIC

Most WIC-authorized retailers are traditional supermarkets and grocery chains. These include stores like Kroger, Safeway, Albertsons, Whole Foods, Trader Joe's, and regional chains specific to your state. Many independent and locally-owned grocers also accept WIC, as do some farmers markets in states that have expanded their WIC programs to include fresh produce purchases.

Convenience stores and pharmacies with grocery sections sometimes accept WIC, but usually only for a limited set of approved foods — typically milk, eggs, and bread rather than the full WIC food list. Dollar stores and discount grocers vary by state and location; some are authorized vendors and some are not. Always check your state's official vendor list before shopping at an unfamiliar store.

What you can and cannot buy with WIC at authorized stores

WIC covers specific foods only: milk, cheese, yogurt, eggs, beans and peas, peanut butter, cereal, bread, infant formula, baby food, and fresh fruits and vegetables (in some states). You cannot use WIC to buy prepared foods, meat, fish, snacks, beverages, or household items — even at stores that accept WIC.

The cashier will scan your WIC card or vouchers, and the register will only allow you to purchase approved foods. If you try to buy something not on the WIC list, that item will be rejected at checkout. You can pay for non-approved items with cash or another payment method at the same time, but your WIC benefits will only cover the approved foods.

Using WIC at farmers markets and specialty retailers

Many states now allow WIC participants to shop at farmers markets using a special WIC card or voucher. This program is called the WIC Farmers Market Nutrition Program (FMNP) in some states. You can use these benefits to buy fresh fruits, vegetables, and herbs directly from farmers. Not all farmers markets participate, so check with your state WIC program for a list of authorized markets in your area.

Some states also authorize specialty grocers that focus on specific cultural foods or organic products. These stores must still be on your state's official WIC vendor list. If you want to shop at a store that is not currently authorized, you can ask your state WIC program whether that store can apply to become a vendor.

What to do if your preferred store does not accept WIC

If a store you prefer to shop at is not on the WIC vendor list, you have two options. First, you can contact your state WIC program and ask whether the store has applied to become a vendor or whether it is may be able to access to apply. Some stores simply have not gone through the authorization process yet.

Second, you can shop for your WIC foods at an authorized store and use your own money at your preferred store for non-WIC items. Many WIC participants do this — they use their WIC benefits at a supermarket for milk, eggs, and bread, then shop elsewhere for other groceries. This approach lets you use your WIC benefits while still shopping where you prefer for other purchases.

Frequently Asked Questions

Can I use WIC at Sam's Club or BJ's Wholesale?

No. Like Costco, Sam's Club and BJ's Wholesale are not authorized WIC vendors in any state. Warehouse clubs do not participate in WIC programs. You will need to shop at a traditional supermarket or authorized grocer to use your WIC benefits.

What if I have a WIC card but the store says they do not accept it?

First, confirm the store is on your state's official WIC vendor list — the store may have lost authorization or the list may be outdated. If the store is listed as authorized, ask to speak with a manager and provide them with your WIC card. If the store's system is not working, they may need to contact their WIC vendor support line. If the problem continues, report it to your state WIC program.

Can I buy WIC foods at Target or Walmart?

Some Target and Walmart locations are authorized WIC vendors, but not all. Check your state's official WIC vendor list to see whether the specific location near you accepts WIC. Authorization varies by store location and state, so you cannot assume all locations of the same chain accept WIC.

Do I have to shop at the same store every time I use WIC?

No. You can use your WIC benefits at any authorized store on your state's vendor list. You can shop at different stores on different days if you want. Your WIC card or vouchers work at all authorized retailers in your state.

What happens if I buy non-WIC foods by mistake?

The register will reject any items that are not on the WIC approved list. You will be told at checkout which items cannot be purchased with WIC. You can pay for those items with cash or another payment method, or you can leave them behind and only purchase the WIC-approved foods.
