How to register as a Maryland 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 with the State Department of Assessments and Taxation (SDAT); every business contracting with Maryland must.
- Create a free eMMA account; the state, local governments and schools all publish solicitations there.
- Select every NAICS/commodity code that applies so eMMA emails you matching solicitations.
- When a notice arrives, read the scope, attend any pre-bid or pre-proposal conference, and send questions only to the procurement officer named in the solicitation.
- Submit a complete bid or proposal before the deadline; late responses are rejected.
- If eligible, self-certify for the Small Business Reserve, or seek MBE or Veteran-Owned (VSBE) certification (MBE certification is run by MDOT).
What to have ready before you start
Registration goes faster when the basics are in front of you. For Maryland, 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 NAICS codes in one sitting.
- Registration and good standing with the State Department of Assessments and Taxation (SDAT); also required for MBE applicants
Does it cost anything to register in Maryland?
No fee is stated on the official pages we read: Free: the official page says eMMA registration is free. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Maryland 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 Maryland use?
Maryland matches vendors to bids with NAICS (the page also refers to them as commodity codes). 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 Maryland
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:
- Minority Business Enterprise (MBE) certification, Maryland Department of Transportation (mdot.maryland.gov)
- Small Business Reserve (SBR) self-certification and VSBE program, Office of Small, Minority & Women Business Affairs (gomdsmallbiz.maryland.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 Maryland
Many Maryland counties, cities and schools post on eMMA too, but some local buyers also use their own systems, so check each one you want to sell to.
Large local governments in Maryland include Baltimore. 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 Maryland
A Maryland registration covers state agencies only. Federal agencies, including the military bases, VA medical centers and national parks in Maryland, 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 Maryland 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, eMaryland Marketplace Advantage 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.
