SAM.gov Registration Guide for Contractors (2026)

What SAM.gov is

SAM.gov is the federal system contractors use for entity registration and federal opportunity search. For construction contractors, this guide focuses on the entity registration mechanics that make a business eligible to bid. A separate overview of how to find government construction bids covers broader discovery topics such as federal, state, and local sources. This page is the deeper registration tutorial.

As of 2026, SAM.gov registration is free. Full registration takes about 10-15 business days. Registration processes change, so verify current steps on the official site before starting or resubmitting an entity record. The most important distinction is that a UEI-only option exists, but full registration is required to bid. For contractors that intend to pursue federal awards, choose the full registration path described below.

SAM.gov also supports opportunity search at sam.gov/search. ConstructionBids.ai ingests SAM.gov opportunities from that search source, but monitoring an opportunity is different from being eligible to submit. You still need the correct entity registration and must follow each solicitation's submission instructions.

Step 1 - Create a Login.gov account

Start by creating a Login.gov account. Login.gov is the sign-in account used to access SAM.gov. Use an email address controlled by the business or by the person your company has assigned to federal registration administration. Do not use a personal address if your company needs continuity when staff roles change.

After creating the account, sign in at SAM.gov. Keep access controls practical. The person handling registration will need enough authority to enter legal business information, tax information, banking details, business details, and representations and certifications. If your company separates accounting, compliance, and estimating responsibilities, gather those details before opening the registration workflow.

Because the exact Login.gov security flow can change, verify current steps on the official site. This guide does not describe authentication details beyond the verified requirement to create a Login.gov account and then sign in at SAM.gov.

Step 2 - Start a new entity registration

After signing in at SAM.gov, go to Entity Registrations and choose Register New Entity. This starts the record for your business. As of 2026, full registration is free and takes about 10-15 business days, so do not wait until a bid deadline is near before beginning.

Contractors should treat entity registration as a prerequisite to federal bidding. If you find a solicitation before your registration is complete, review the solicitation instructions and verify current steps on the official portal, but do not assume you can finish registration instantly. The processing timeline can affect whether your business is ready to bid.

Use internal records to decide who owns the SAM.gov entity. The registration owner should be able to maintain the record over time, respond to validation issues, and coordinate updates when legal, tax, banking, or certification information changes.

Step 3 - Select All Awards for full registration

When SAM.gov asks what type of registration you need, select All Awards. The verified fact for this guide is direct: full registration is required to bid, not UEI-only. A UEI-only option exists, but it does not replace the full registration needed for federal bidding.

This step is where many contractors should slow down. A business may only need a Unique Entity ID for certain non-bidding situations, but a contractor preparing to submit federal bids needs the full registration path. If your goal is to bid on federal construction work, choose All Awards and continue through the full multi-section registration.

If the page wording changes or SAM.gov presents additional choices, verify current steps on the official site before proceeding. Do not choose a lighter registration path simply because it appears faster. A faster path that does not support bidding can create delays later when an opportunity is already moving.

Step 4 - Validate the entity name and address

Entity validation is one of the most important parts of SAM.gov registration. Enter the legal business name and address exactly as they appear on IRS records. The verified fact for this guide is that mismatch with IRS records is the number-one cause of rejections.

Use the business's official legal name, not a shortened trade name unless that is what appears in the relevant official records. Confirm punctuation, abbreviations, suite numbers, and address format before submitting. If your company recently moved, changed names, reorganized, or uses multiple locations, align the registration with the correct IRS record before continuing.

During entity validation, SAM.gov assigns a UEI, or Unique Entity ID. The UEI replaced the old DUNS number. Keep the UEI in your internal procurement records because agencies, prime contractors, and internal teams may ask for it when reviewing vendor eligibility or federal opportunity records.

Step 5 - Complete Tax ID and IRS verification

Complete the Tax ID section using the correct EIN or TIN. SAM.gov verifies the tax information against IRS records, so the legal name, address, and tax identifier must be internally consistent. If your accounting records use a different formatting style than legal records, confirm the official version before submitting.

This is not the place to guess. Ask the person responsible for tax records to confirm the EIN or TIN and the legal business name associated with it. If the registration is rejected because the tax details do not match IRS records, the bid-readiness timeline can slip.

Where SAM.gov asks for details not covered in this guide, use your official business records and verify current steps on the official site. The purpose of this section is to establish the entity identity used for federal registration, not to market your company or describe project experience.

Step 6 - Add banking and EFT information

Complete the banking and EFT section with the routing and account information used for electronic payment. EFT information matters because federal awards require a reliable payment route. Use an account approved by the business for federal payments and confirm the routing and account numbers before submitting.

Handle this step with access discipline. The registration user may need banking details, but that does not mean the information should be copied into unofficial notes, shared in unsecured messages, or stored outside approved company systems. Enter banking details only in the official SAM.gov registration workflow.

If your business changes banks later, the SAM.gov entity record may need to be updated. Assign ownership for maintaining the record after initial approval so payment details, tax details, and certifications do not become stale.

Step 7 - Complete business details and Reps & Certifications

Complete the remaining business details and Reps & Certifications sections. The verified registration scope includes business details and representations and certifications. These sections help establish how the entity is represented in the federal procurement system.

Read each certification carefully and answer according to your company's current facts. If a question requires legal, tax, ownership, or compliance interpretation, route it to the person responsible for that area before submitting. Do not copy answers from another company or an old record unless they have been checked against current business facts.

This guide does not cover NAICS strategy, set-aside positioning, or ITB-vs-RFP response strategy because the live government construction bids guide already covers those topics at a higher level. Keep this page focused on completing the entity registration correctly.

Step 8 - Submit and wait for UEI/CAGE processing

Submit the full registration after reviewing every section. As of 2026, full SAM.gov registration is free and takes about 10-15 business days. A UEI is assigned during entity validation, and a CAGE code is auto-assigned for US entities.

Save the confirmation and keep the UEI with your procurement records. Also note the person responsible for maintaining the entity record. Federal registration is not a one-time document that should be forgotten after approval. Company changes can require updates, and solicitation deadlines do not wait for administrative cleanup.

If SAM.gov requests a correction or additional validation, respond through the official portal and verify current steps on the official site. Since entity validation name and address mismatches are the number-one cause of rejections, start troubleshooting by comparing the legal business name and address against IRS records exactly.

How to find and submit a bid on SAM.gov

After registration, contractors can search federal opportunities at sam.gov/search. Use the opportunity record to review the solicitation, attachments, deadlines, amendments, and agency instructions. ConstructionBids.ai ingests SAM.gov opportunities from sam.gov/search, which can help your team monitor federal bid leads alongside state, local, and other portal sources.

Actual bid submission happens according to the solicitation instructions. In many cases, the instructions may send vendors to an agency system, email process, upload location, or other official response method. Because submission paths vary and the verified facts for this guide do not define a universal SAM.gov submission workflow, follow the solicitation exactly and verify current steps on the official portal.

Do not treat discovery as submission. Finding a SAM.gov opportunity only tells you that the opportunity exists and where the instructions live. Your team still needs to confirm eligibility, read the documents, track amendments, prepare the response, and submit by the method the agency requires. If you are building a broader monitoring stack, compare dedicated portals such as BidNet Direct with centralized tools in our guide to construction procurement software.
