Costco store locations can be found on the Costco website. The site features a store locator that allows users to input an address, ZIP code or city name. The site then displays all nearby Costco locations within a certain distance of the searched-for location.
The Costco store locator allows users to search for specific features at different Costco stores, such as gas stations, food courts and pharmacies. Costco shopping services are only available to Costco members. As of June 2015, a Costco membership costs $55 a year in the United States for a Business membership, and $110 a year for an Executive membership.
