How can I gain access to Costco’s vendor portal?

Costco’s vendor portal, also known as Costco’s Extranet, is a web based system that provides Costco vendors with access to a plethora of important information. The system is a free and secure accounting tool that allows vendors to track and maintain records of purchases and payments.

And it doesn’t stop there. The vendor portal keeps updated records of important forms and memos as they are released by Costco, as well as additional vendor maintenance and vendor services tools.

However, the extranet is only available to Costco vendors with a valid vendor number. Potential vendors do not have access to Costco’s vendor portal until they receive a vendor number.
