How to register as a Connecticut 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.
- Gather your organization details, taxpayer ID (TIN/FEIN/SSN), business type and a main contact email before you start.
- Open the CTsource supplier registration and accept the general disclaimer.
- Fill in your organization and main contact information; that email receives bid notices.
- Choose the UNSPSC commodity and service codes that fit your business (the state links a UNSPSC lookup tool).
- Submit; a confirmation page and email follow, and you can then log in to manage your profile and answer solicitations.
- If you are a Connecticut-based independent small business, consider DAS Small Business certification (it requires a SAM registration and a CT Gateway application).
What to have ready before you start
Registration goes faster when the basics are in front of you. For Connecticut, 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 UNSPSC codes in one sitting.
- Taxpayer ID (TIN/FEIN/SSN) to register
- SAM registration is required for DAS small business certification
Does it cost anything to register in Connecticut?
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 Connecticut 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 Connecticut use?
Connecticut matches vendors to bids with UNSPSC. UNSPSC is the United Nations Standard Products and Services Code, a four-level product code set. Choose the most specific codes that match your goods or services; buyers send bid notices by these codes. 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 Connecticut
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:
- DAS Small Business Certification Program (SBE/MBE set-aside) (portal.ct.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.
Small business. Small business programs reserve some purchases for firms under a size limit, or give them a preference when bids are close. The size limits are set by each program, not by the federal SBA tables, so check the state's own definition.
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 Connecticut
Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not put you on every local list.
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 Connecticut
A Connecticut registration covers state agencies only. Federal agencies, including the military bases, VA medical centers and national parks in Connecticut, 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 Connecticut 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, CTsource 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.

What codes does Connecticut use for vendor registration?
Connecticut uses UNSPSC. Pick every code that matches what you sell, because the codes decide which bid notices you receive.

No. Certification is optional and separate from registration. Programs such as DAS Small Business Certification Program (SBE/MBE set-aside) can open set-asides or count toward participation goals.
Does registering with Connecticut cover cities and counties?
Usually not. Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not put you on every local list.
Is Connecticut vendor registration the same as SAM.gov?
