Is Costco Customer Service Available 24/7?
No. Costco does not list its main customer service phone lines as 24/7 services.
The membership and warehouse line, 1-800-774-2678, is open Monday through Friday from 6 a.m. to 6 p.m. Pacific Time and Saturday and Sunday from 8 a.m. to 5 p.m. PT. Costco.com and Costco Logistics support at 1-800-955-2292 has longer hours, from 5 a.m. to 8 p.m. PT on weekdays and 5 a.m. to 7 p.m. PT on weekends.
Technical and warranty support is listed as the broadest phone service, operating Monday through Sunday from 5 a.m. to 8 p.m. PT.
What Are Costco Customer Service Hours?
Costco customer service hours depend on the department. For most common questions, the two numbers to remember are:
Membership: 1-800-774-2678
Costco.com orders: 1-800-955-2292
Costco also provides separate live-chat hours. Membership and warehouse chat is available Monday through Friday from 6:30 a.m. to 5:30 p.m. PT and Saturday and Sunday from 8 a.m. to 5 p.m. PT. Costco.com chat follows the online-order schedule of 5 a.m. to 8 p.m. PT Monday through Friday and 5 a.m. to 7 p.m. PT on weekends.
Because hours can change, checking Costco’s official Contact Us page before calling is the safest option.
What Is the Costco Customer Service Phone Number for Appliances?
For appliances purchased through Costco.com or delivered by Costco Logistics, call 1-800-955-2292. Costco identifies this number for Costco.com online orders and orders delivered through Costco Logistics.
This number is also used for many appliance delivery and installation issues. Costco’s current appliance guidelines direct members to this number when they need help rescheduling certain delivery appointments or have questions related to delivery and installation.
For an appliance purchased from a physical warehouse, the appropriate assistance may depend on the purchase and local department. The Costco Customer Service site or local warehouse can help direct the request.
Does Costco Customer Service Have an Email?
Costco says it does not offer general customer service by email. Instead, it currently provides customer assistance through phone and chat. Members who want to submit comments or suggestions can use Costco’s feedback options.
This means an online search for a general Costco customer service email address can lead to outdated or unrelated information. For a real-time customer service issue, Costco recommends its official phone or chat options.
How Can I Speak to a Live Person at Costco?
The simplest way to reach a live Costco representative is to call the department that matches your issue.
For membership questions, call 1-800-774-2678. Costco says members can also speak with team members at the membership counter at a local warehouse.
For Costco.com orders and Costco Logistics, call 1-800-955-2292. Costco also provides a Chat Us option during its listed chat hours.
For a warehouse department such as Pharmacy or Tire Center, Costco recommends finding the local warehouse and calling that location directly.
How Do I Contact Costco Customer Service About an Online Order?
For an online order, use 1-800-955-2292 or Costco’s online customer service tools. Costco’s customer service center includes options for My Orders, Return/Replace Order, Order Status/Shipping, Cancel Order, Price Match, and account assistance.
Many requests can be handled without calling. After signing in to Costco.com, members can use the available order-management options to review an order, request a return or replacement, or make eligible changes. Costco also provides online help for delivery and installation services.
Costco Wholesale Customer Service
Costco Wholesale customer service provides help with memberships, warehouse questions, Costco.com orders, returns, and other services. The main contact depends on the type of issue you need to resolve.
For general membership and warehouse assistance, Costco lists 1-800-774-2678. For Costco.com orders and Costco Logistics, the number is 1-800-955-2292. Costco also offers live chat through its customer service website during its listed support hours.
For questions about a specific warehouse department, such as the Pharmacy or Tire Center, it is better to contact the local warehouse directly. Department hours and contact information can vary by location.
Trader Joe’s vs Costco Customer Service
Trader Joe’s and Costco handle customer service differently. Costco separates support by service type, with dedicated contact options for membership, online orders, and technical or warranty assistance. Trader Joe’s generally directs customers through its customer relations and store-level support channels.
Costco is often more structured for issues involving memberships and online purchases because its customer service system includes separate departments. Trader Joe’s focuses heavily on store-level assistance and customer relations.
For shoppers comparing the two, the better option depends on the issue. A Costco member dealing with an online order or membership account can use dedicated phone or chat support, while a Trader Joe’s customer may need to work directly with the store or customer relations team.
Costco Citi Card Customer Service
The Costco Anywhere Visa® Card by Citi is handled by Citi rather than Costco’s regular warehouse customer service. This means questions about the credit card account, payments, transactions, statements, or card security should generally be directed to Citi.
Costco customer service can help with Costco membership and warehouse-related matters, but it is not the primary support channel for managing a Costco Citi card account.
For card-related problems, use the customer service number shown on the back of the card or sign in to your Citi account for the appropriate support options. This is especially important for urgent issues such as a lost or stolen card, unauthorized transactions, or payment problems.
How Do I Contact Costco About Returns?
Costco provides self-service return and replacement options for many Costco.com purchases. Its customer service center includes a Return/Replace Order option, while eligible online purchases can also be returned through the Costco website or according to Costco’s return procedures.
For a warehouse purchase, members can also contact or visit their local Costco membership or returns area. The exact process can depend on the item and how it was purchased.
Does Costco Have a Chat?
Yes. Costco offers live chat through its customer service website. Members can select the Chat Us option to connect with support during the published chat hours.
Chat is useful for questions about membership, inventory, online orders, and other customer service topics. Costco notes that some membership transactions cannot be completed through live chat and may require a phone call or a visit to a warehouse membership counter.
What Is the Costco $20 Rule?
There is no general official Costco customer-service policy known as the “$20 rule.” Costco’s official customer service and membership materials do not identify a universal rule requiring shoppers to spend $20 or providing a special $20 customer-service benefit.
There are, however, legitimate Costco offers that involve $20, such as promotional Digital Costco Shop Cards for qualifying new members. Those promotions have their own eligibility rules and should not be confused with a general store policy.
Do Seniors Get Free Costco Membership?
No. Costco states that it does not offer free or discounted memberships based on being a senior. Its membership information lists regular membership options and says Costco does not offer free or discounted memberships.
Current standard U.S. membership pricing listed by Costco is $65 per year for Gold Star and $130 per year for Executive, before applicable sales tax. Executive Membership includes additional benefits, including a 2% annual reward on qualifying purchases, subject to terms and exclusions.
How Can I Find My Local Costco Customer Service?
For a local warehouse, use Costco’s official Find a Warehouse tool and search by city, state, or ZIP code. The location page provides the warehouse’s phone number, hours, holiday closures, and information about services such as Pharmacy, Gas Station, and Tire Center when available.
Local departments may have different hours from the main warehouse. Calling the specific warehouse is the best way to reach departments such as Pharmacy or Tire Center.
