FAQ’s

When did Costco Wholesale Corporation go public?

Costco went public on December 5, 1985. On that date it offered shares at US$10.00 per share before stock splits. Adjusted for later stock splits, the effective per share initial price is less.

Where are Costco Wholesale Corporation offices and work locations?

Costco operates hundreds of warehouses globally. As of 2024-2025, Costco has approximately 900-plus warehouse locations worldwide, with the majority in the United States, many in Canada and Mexico, and others in countries such as Japan, United Kingdom, South Korea, Australia, Taiwan, China, Spain, France, Sweden, Iceland, New Zealand. Their offices include the headquarters (Issaquah, Washington), regional corporate offices in countries where they operate subsidiaries, and logistics/distribution / fulfillment centers (for example Innovel in the U.S. for big-item delivery).

Does Costco Provide Container Shipping for Members and Its Global Supply Chain?

Costco does have container shipping services, though it is not widely advertised in the same way as its retail membership. Costco primarily offers shipping for bulk and oversized items through its logistics subsidiary (formerly Innovel Solutions, now part of Costco Logistics). For members who purchase large items such as appliances, furniture, or other heavy goods, Costco can arrange freight and container shipping directly to homes or businesses.

For international shipping, Costco does not operate like a freight forwarder for members, but it does engage in container shipping for its supply chain. In fact, Costco charters its own container ships and leases shipping containers to secure supply lines, especially during times of global shipping disruptions. For example, in recent years Costco chartered several vessels and thousands of containers to transport goods from Asia to North America in order to bypass congestion and keep its warehouses stocked.
