2023 Guide to Costco Citibank Customer Service

Costco and Citibank are two of the most trusted brands in their respective industries. Costco is known for providing quality products at affordable prices, while Citibank offers exceptional financial services to its clients. In 2016, Costco and Citibank joined forces to offer a co-branded credit card, the Costco Anywhere Visa® Card by Citi.

With Costco’s massive customer base and Citibank’s extensive financial expertise, the partnership was set to disrupt the credit card industry. But with any financial service, customer service plays a crucial role in determining customer satisfaction. In this guide, we’ll take an in-depth look at the Costco Citibank customer service experience and what you can expect as a cardholder.

Understanding the Costco Citibank Partnership

Before we dive into the customer service experience, let’s first explore how the partnership between Costco and Citibank came about. For over two decades, American Express was the exclusive credit card provider for Costco. However, in 2015, Costco announced that it would be ending its relationship with American Express and partnering with Citibank and Visa instead.

The transition took place on June 20, 2016, and all existing American Express Costco cards were automatically converted to the Costco Anywhere Visa® Card by Citi. This new card offered more benefits and rewards than the previous American Express card, such as:

  • 4% cashback on eligible gas purchases (up to $7,000 annually)
  • 3% cashback on restaurants and travel
  • 2% cashback on Costco purchases
  • 1% cashback on all other purchases

Now that we know how the partnership came about let’s explore the customer service experience.
