An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Costco phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Costco staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy day to call Costco is Friday. The most busy day to call Costco is Wednesday.  Again, this is based on a sample of 9,697 calls made with our AI-powered, web-based phone in the last 90 days.

We measured the shortest hold times to be on Thursday. The longest wait in the queue on average occurs on Friday. 

The best time to call

In summation, the best day to call Costco is Friday.  This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that Costco staffs the call center well on Friday.

  • Each customer service department has its own hours. Warehouse and membership customer service is available from Monday to Friday, from 6 am to 6 pm Pacific time. Saturday to Sunday, from 8 am to 5 pm Pacific.
  • If your problem or question pertains to a local warehouse, such as a lost item, poor service from an employee, or a question about business hours, call the warehouse directly.
  • Have your membership number in front of you. You'll find this on your card or on correspondence from Costco.

Costco customer service representatives can handle a range of issues, including membership enrollments and renewals, e-commerce issues and comments and concerns about customer satisfaction.

What Can't Easily Be Resolved Over the Phone with Costco?

There are some issues that are not easily resolved by calling Costco:

  • Individuals who sign up for a Costco membership online or over the phone must visit a local Costco store to complete their registration and obtain a membership card. Costco membership cards include a photograph of the member, so an in-store visit is a must.
  • Returns must be made at a store or by mailing the product back to Costco.
  • Costco.com offers a price adjustment service: If the price you paid on Costco.com for an item drops within 30 days of purchase, you can request an adjustment. However, adjustments can only be completed via an online form.
  • Requests for technical support may require you to bring your item into a warehouse for repair.

What Can I Do if my Call to Costco is Unsuccessful?

Calls to good companies sometimes go bad. If you get off the phone with Costco and feel as though you didn't accomplish anything, don't fret. There are options available to you.

The first thing to do is take some notes on what happened during your call. Try to remember the representative's name, and take down the date and time of your conversation. This can be very useful if you need to escalate your case.

  • Try calling Costco again. You may be able to connect with a representative who has more experience or training and who can resolve your issue.
  • Costco offers a live chat option on its website. One advantage to live chat is that you'll have a written record of your communication.
  • Costco does not offer the option of communicating via email or via social media platforms. You can, however, send a letter via postal mail. If you go this route, make sure that you send your letter with delivery confirmation. This will be useful if you don't receive a response and need to escalate your case.
  • Visit your local Costco and ask to speak to a manager. In some cases, talking to someone who is directly in front of you may be what is needed to communicate effectively and discuss your options and alternatives.
