- 01
Register on BuyNet supplier registration

Watch the other buyers
State agencies in California buy through the state portal, and school districts, transit agencies and utilities in the area usually post on their own sites. Registering with County of San Diego does not register you with them.
What you will typically need
Exact requirements vary by portal; the registration page linked above is the authority. Most ask for:
- Your legal business name and address exactly as registered with the state, and your federal tax ID (EIN, or SSN for some sole proprietors).
- A signed IRS Form W-9, which most buyers collect before they can pay you.
- Commodity codes (NIGP, UNSPSC or NAICS, depending on the portal) for every product and service you sell.
- A contact who will receive bid notices, plus any business license or registration the jurisdiction requires.
- Certificates of insurance and, for construction, bonding capacity: these are usually requested per bid rather than at registration.

Tips
- Email alerts only cover the commodity codes on your profile, so pick codes carefully.
