Why Issaquah?

Costco moved its headquarters to Issaquah in 1996 from nearby Kirkland, Washington. The Kirkland Signature private label brand—now one of the most recognized store brands in retail—was named after that original headquarters location.

Issaquah offered more space for expansion while keeping Costco close to its Pacific Northwest roots. The region's logistics infrastructure, including the Port of Seattle, supports Costco's massive import operations from Asia.
