How to register as a Washington vendor, step by step
These are the steps as the state describes them, in plain words. The portal may word things differently, and it can change, so keep the official page open beside you.
- Register your business in WEBS, the state's system where agencies must post their goods and services solicitations.
- Enter your business information and contacts, and accept the WEBS vendor terms.
- Pick the commodity codes that match what you sell; you can search for them by NAICS code if you know yours.
- Add the DES customer-service address to your safe senders so bid notices and award emails reach you.
- Check the WEBS bid calendar regularly too, in case you missed a code, and respond to solicitations that fit.
- If eligible, apply for minority- or women-owned business certification with the Office of Minority and Women's Business Enterprises (OMWBE).
What to have ready before you start
Registration goes faster when the basics are in front of you. For Washington, gather:
- Your legal business name exactly as it appears on your tax records, and any trade name you use.
- Your federal Employer Identification Number (EIN), or a Social Security number for a sole proprietor, since the state uses it to match you for payment.
- A business address, a phone number and an email address that someone reads every day; bid notices and questions from buyers go there.
- A short list of what you sell, so you can choose the matching WEBS commodity codes, searchable by NAICS codes in one sitting.
The pages we read did not list any extra state tax certificate or form for registration itself; individual bids can still ask for insurance, licenses or a bond.
Does it cost anything to register in Washington?
No fee is stated on the official pages we read: No fee stated on the official page. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Washington does not require you to use a paid middleman to sell to its agencies. Some separate things can cost money, such as a notary for a form, a professional license, insurance or a bid bond on construction work.
Which commodity codes does Washington use?
Washington matches vendors to bids with WEBS commodity codes, searchable by NAICS. NAICS codes are the federal industry codes from the U.S. Census Bureau. They describe what kind of business you are, so the same codes you use in SAM.gov usually work here too. If you also want federal work, you will need NAICS codes for SAM.gov; our free NAICS code lookup and the guide what a NAICS code is help you pick them.
Certification programs in Washington
Certification is separate from registration. You can register and bid without it, but a certificate can open set-aside contracts or count toward goals that agencies and prime contractors have to meet. The programs the state points to:
- State certification for minority- and women-owned businesses (Office of Minority and Women's Business Enterprises, OMWBE) (omwbe.wa.gov)
MBE/WBE. Minority- and women-owned business certifications show that a firm is at least 51% owned and controlled by people in those groups. State agencies use them to count toward participation goals, and some cities and counties accept the state's certificate in place of their own.
Federal programs such as 8(a), HUBZone, women-owned (WOSB) and service-disabled veteran-owned (SDVOSB) are certified by the U.S. Small Business Administration, not by the state; see small business set-asides explained.
Cities, counties and school districts in Washington
Not every public agency in Washington is required to post in WEBS, so cities, counties, ports and school districts may use their own bid lists; check each local buyer you want to sell to.
Large local governments in Washington include Seattle, Spokane, Tacoma, Vancouver. Each one usually keeps its own vendor list and posts its own bids, so register with the ones you want to sell to as well.
EasBid reads many of these local sources together with the state's, so one search shows state and local bids side by side.

Federal contracts in Washington
A Washington registration covers state agencies only. Federal agencies, including the military bases, VA medical centers and national parks in Washington, buy through SAM.gov, which has its own free registration and gives you a Unique Entity ID. Our step-by-step guide to registering in SAM.gov walks through it, and federal bids on EasBid lists open notices.
Tips for your first Washington bid
- Read the whole solicitation before you price anything; the due date, the question deadline and the submission method are usually on the first pages. Our guide on reading a solicitation shows what to look for.
- Ask questions in writing before the question deadline. Answers are usually posted as an addendum that every bidder can see.
- Check whether the bid needs a license, insurance certificate or bond, and get those started early.
- Submit through the channel the notice names, Washington's Electronic Business Solution or otherwise, and leave a day of margin; late bids are normally rejected.
- Whether you win or lose, ask for the award results. They show the winning prices and help you price the next one.
