Costco Hours: What Time Does the Store Open and Close?

COSTCO stores are a great option for customers who like to buy groceries and other household items in bulk, but the retailer requires customers to pay annual membership fees.

While the warehouse chain is open nearly year-round, Costco operates limited hours — or closes for an entire day — on select federal holidays.

What are Costco hours of operation?

Costco stores generally open their doors between 9am and 10am local time and close around 8:30pm on weekdays.

Most Costco stores are also open from 9:30am to 6pm on Saturdays and 10am to 6pm on Sundays.

Hours of operation also vary between stores, so shoppers should check with the nearest Costco warehouse in advance to avoid shopping mishaps.

Shoppers can also find the Costco closest to them using the company’s website Find a warehouse online resource.

Costco also offers various services in its warehouses, such as gas stations, pharmacies, food courts and even opticians.

These may have different opening and closing times to the real store, for example opening later than the warehouse or closing earlier than the real store.

For warehouse service hours, use the Find a Warehouse feature and select the Store Details section.

Any service with the same opening hours as the store itself will only have a telephone number listed next to it, while services with different opening times will have their own opening and closing times.

For shoppers on the go, the Costco app also offers updated opening and closing times for all stores.

It is also free to download from iTunes or Google Play app stores.

Is Costco closed on any holidays?

Costco stores are generally closed on select federal holidays.

These holidays include:

Select Costco locations may also open later or close early on other holidays or holiday-adjacent days of the year, including:

During the Covid-19 pandemic, Costco has offered healthcare workers, first responders and seniors an extra hour of shopping, typically an hour before opening its doors to all of its members.

However, these hours officially ended in April 2022, and most stores have returned to normal operating hours for all members.

Some locations may still offer additional hours for seniors, disabled members, or immunocompromised members, so again, shoppers are encouraged to check in at their local Costco warehouse.

What are the rules for shopping at Costco?

Technically, there’s one caveat to shopping at Costco — it’s a members-only club.

Costco warehouses are not open to the public, meaning customers need to purchase one of three annual subscriptions to shop at the big-box retailer.

Gold Star membership costs $60, includes a free domestic card, and is valid at all Costco stores worldwide.

This option is best for single guests or families.

Costco merchant membership also has a $60 fee, includes a free domestic card, and is valid at all Costco locations worldwide.

This membership also allows members to purchase items for resale, but customers must provide Costco with all appropriate resale information.

Business members can also add affiliate cardholders for $60 per person.

Costco’s Executive Membership costs $120 – this includes a $60 membership fee, along with a $60 upgrade fee.

This membership offers additional benefits and greater savings on Costco services, extra benefits on select Costco Travel products, and a 2% annual reward on eligible Costco purchases.

Memberships are valid for a period of 12 months from the date of registration.

Shoppers are required to show their membership cards when entering a Costco warehouse and when checking out at a payment register.

All frequently asked questions, rules and membership restrictions can also be found at Costco website.
