What Time Does Costco Open and Close? 2026 Hours by Membership Type

How Costco Hours Vary by Membership Type

Costco operates three membership tiers, and each has different warehouse access times. The official Costco website shows that membership type determines when you can shop.

Executive members can shop one hour earlier on weekdays and one hour earlier on Sundays compared to Gold Star and Business members. On Saturdays, Executive members open at 9:00 AM while Gold Star and Business members open at 9:30 AM. This early-access benefit is one of the perks of Executive membership, which costs more annually but includes an annual reward.

Department-Specific Hours

While the warehouse itself opens and closes at the times listed above, some departments operate on different schedules. The pharmacy, tire service center, optical department, and hearing aids have their own hours that may differ from main warehouse hours.

Pharmacy hours typically match warehouse hours but may have a closure period. When only one pharmacist is on duty, the pharmacy may close for up to 30 minutes between 1:30 PM and 2:00 PM for breaks. Pharmacy hours vary by location, so call ahead if you need a specific service.

The tire service center operates during the same hours as the main warehouse for all membership types. Costco recommends scheduling tire appointments in advance through its online appointment system at costcotireappointments.com, though walk-in service is also available based on bay availability.

Gas stations at Costco locations often open earlier and close later than the warehouse itself. For example, at many locations, the gas station opens at 6:00 AM on weekdays and closes at 10:00 PM, providing hours that extend beyond warehouse access times. Gas station hours vary by location.

Holiday Closures

Costco closes on certain holidays regardless of membership type. Labor Day is one confirmed closure date when both the warehouse and gas station are closed. Check with your local warehouse for other holiday closures, as some locations may have additional closings on major holidays.

How to Find Your Local Costco Hours

The most reliable way to confirm hours for your specific location is through Costco’s official store locator at costco.com. Enter your zip code or city, and the search results display the warehouse address, phone number, and complete hours breakdown by membership type.

Calling your warehouse directly is another option. The phone number appears on the store locator page. Staff can confirm current hours, explain any temporary changes, and answer questions about department-specific schedules.

Hours listed online are current as of the date the page was last updated, but Costco may occasionally adjust hours for specific locations. If you are planning a visit, especially during unusual times, a quick call ensures you do not make an unnecessary trip.

Early Access for Executive Members

Executive membership includes the benefit of shopping one hour before Gold Star members on most days. This early access allows Executive members to shop during less crowded times and is particularly valuable during peak shopping periods or when items may be in short supply.

The one-hour difference applies Monday through Friday and on Sunday. On Saturday, the difference is 30 minutes. These time advantages are exclusive to Executive members and cannot be shared with non-member household members; each household member must have their own membership to access early shopping hours.

Comparing Costco to Other Retailers

Costco’s membership-based hours differ from typical retail store structures. Walmart store hours are generally the same for all customers regardless of status, and Target store hours do not vary by membership type. Aldi store hours are also uniform across membership categories. Costco’s tiered access system is unique to warehouse club membership models.

Planning Your Costco Visit

To maximize your Costco shopping experience, verify membership type before planning your visit. If you have a Gold Star or Business membership and want to shop at 9:00 AM on a weekday, you will need to wait until 10:00 AM. Executive members planning an early morning trip can take advantage of the one-hour head start.

Note that visiting during off-peak hours, such as weekday mornings or early afternoons, typically results in shorter checkout lines and easier product selection. Weekends and evenings are busier across all warehouses.

If you plan to use specialty services like the tire center or pharmacy, confirm those departments are open at your preferred time. Calling ahead eliminates the risk of arriving to find a department closed for a lunch break or staffing change.
