Our legacy system (Online Vendor Registration) is retired effective October 23!
Solicitations advertised before October 23 will still appear in the legacy system. Those advertised after that date will only appear in the new King County E-Procurement Supplier Portal. New supplier accounts in the legacy system will only be allowed in limited circumstances. 

To view solicitations

Anyone may view solicitations in the legacy system until Q2 2021. You may enter the site as a guest or log into your existing supplier profile.

If you need to create an account in the legacy system in order to receive notifications of an in-flight solicitation, email
