Contacting Costco Customer Service Center
Costco is a wholesale warehouse store. In order to shop Costco online of offline, you must pay for a membership. In some cases, the warehouse will offer new customers a temporary membership for one to two weeks to test out the warehouse shopping experience. Some of the items available for sale online can be purchased from home and picked up in a local Costco warehouse, but others require shipping to your home.

The main page of the official Costco website is http://www.costco.com/. Customers can choose to log in to their shopping account using the link at the top of the page. You can also check on your order using the order number included in the verification email.
Customer service contact information is listed under the Customer Service tab. There is no contact us page.
Customer Service Email
Instead of offering a customer service email address, Costco offers a contact form https://costco.egain.net/system/selfservice.controller?CONFIGURATION=1001&PARTITION_ID=1&CMD=STARTPAGE&USERTYPE=1&LANGUAGE=en&COUNTRY=us. The form asks for the subject of your email, details of the message and some personal information like name, email and contact phone number. You can also add your membership account number or order number if desired.
We sent an email to test the response time for a simple question. When we receive a response from the customer service department we will update our experience.
All of the customer service phone numbers for Costco customer service are for members, unless you want to learn more about membership. We called the general membership line to test phone customer service. We were given the opportunity to press 0 to talk with a representative during the automated message. After pressing 0 we were placed on hold (with music) to wait for the next representative. The total call was less than three minutes. We asked about membership pricing and the customer service representative answered without pause.
As one of the largest companies in the United States as well as the world, we expected customer service from Costco to be top-notch. Costco definitely lived up to it’s reputation. We erceived a response to our email inquiry with 4 hours from a customer care representative. They answered our question as well as provided additional information not requested. See below:

Thank you for your e-mail to Costco Wholesale.
No, you do not have to be a member or purchase a membership online to place an order, however all non members will be charged a 5% non member surcharge except California state residents.
