Costco finds a replacement for Amex

Costco has a new credit card partner for its stores, and it’s a brand name that shoppers may already be very familiar with.

The retailer has entered into a new co-brand credit card program agreement with Citi and an acceptance and co-brand incentive agreement with Visa.

Under the terms of the agreements, Citi, the world's largest issuer of consumer credit cards, would become the exclusive issuer of Costco's co-brand credit cards and Visa will replace American Express as the credit card network for Costco in the United States and Puerto Rico beginning April 1, 2016.

Once issued, Costco's co-brand Visa credit card would provide generous rewards to Costco members, serve as the Costco membership card, and would be accepted at Costco locations in the United States and Puerto Rico, as well as all merchants worldwide that accept Visa credit cards.

Costco says it will provide its members with additional information in the coming months regarding the anticipated transition from its existing co-brand credit card program.

Costco said last month that American Express would stop being the card partner and the payment network for its U.S. stores. American Express said the loss of the contract after 16 years would hurt its earnings for the next two years.

Costco operates 671 warehouses, including 474 in the United States and Puerto Rico, 88 in Canada, 34 in Mexico, 26 in the United Kingdom, 20 in Japan, 11 in Korea, 10 in Taiwan, seven in Australia and one in Spain.
