There are three kinds of Costco membership offered: the Gold Star, Executive, and the Business.
What’s good about the membership is that all Costco cards can be used WORLDWIDE and at Costco.com. So you may have membership here in United States and you can also use that if you go to Costco in Japan, Canada, Taiwan, Spain, South Korea, Mexico, Australia, Puerto Rico, or United Kingdom.
