How to Register in SAM.gov: A Step-by-Step Guide for Small Businesses
August 6, 2026 · 5 min read
If you want to sell directly to the federal government, learning how to register in SAM.gov is one of your first concrete steps. The System for Award Management is the federal government's official entity-registration and procurement database. An active registration is generally required to receive federal awards and payments, and contracting officers use the record to verify your company. Registration is free, but it is detailed and can take time—so prepare before you start.
UEI versus DUNS: understand the transition
SAM.gov now uses the Unique Entity ID (UEI) as the primary identifier for entities doing business with the federal government. The government moved away from the DUNS number for federal award identification. You do not need to purchase a DUNS number to register, and legitimate registration assistance should not charge you for a UEI.
A UEI identifies your legal entity; it does not prove that you are small, 8(a), SDVOSB, WOSB, or HUBZone-certified. Those programs have separate eligibility and certification requirements. Use the exact legal name and physical address associated with your business records. A mismatch can delay validation even when the company is legitimate.
Prepare before opening the registration
Gather your legal business name, physical address, mailing address, incorporation or formation details, tax identification information, bank and payment details, fiscal-year end, points of contact, ownership information, and primary and secondary NAICS codes. Review your formation documents and IRS records first. Decide who will be the entity administrator and who may submit or update the registration.
You will also need a clear description of your capabilities, representations and certifications, size information by NAICS code, and information about your ownership and socioeconomic status. Have your capability statement and website available, but remember that a marketing description cannot override the official legal record.
Step-by-step: how to register in SAM.gov
- Create a Login.gov account. Use an email your company can reliably access and protect the account with multifactor authentication. SAM.gov uses Login.gov for identity and account access.
- Choose entity registration. Start a new registration rather than assuming an old record exists. Search for your entity and review any existing record carefully.
- Request or confirm your UEI. Enter the exact legal name and address. If the system asks for evidence, provide formation or tax documentation that matches the entry.
- Complete core entity information. Enter physical and mailing addresses, incorporation details, fiscal-year end, points of contact, and electronic funds transfer information accurately.
- Add assertions and representations. Select NAICS codes that reflect work you can actually perform, provide employee and revenue information, and complete size and ownership questions honestly.
- Complete federal award and responsibility sections. Read each representation, including exclusions, proceedings, and compliance questions. Ask a qualified adviser about an unusual fact rather than guessing.
- Review, certify, and submit. Check spelling, addresses, bank details, codes, and contact emails. The person submitting certifies that the information is true and complete.
- Save your confirmation. Record the submission date, UEI, registration expiration date, and any validation case number. Monitor email and the SAM.gov workspace for requests.
Entities and roles matter
An entity registration and a user account are different things. The entity is your company; roles are permissions for people who work on its record. Assign an administrator who will remain with the business, add a backup, and remove former employees promptly. A consultant may help prepare information, but do not share Login.gov credentials or give an outside party more access than necessary.
Keep contact information current because validation questions and renewal notices go to those addresses. If your company has subsidiaries, branches, or affiliates, confirm which legal entity is actually contracting. Registering the wrong entity can create serious payment and eligibility problems.
Validation timeline and common rejections
SAM.gov validates identifying information against government and commercial sources. Some registrations move quickly; others take several business days or longer when names, addresses, or tax records do not match. Build registration time into your contracting plan and do not wait until a proposal deadline. An active registration is a prerequisite, not a last-minute form.
Common problems include using a virtual office instead of the legal physical address, abbreviating the name differently from formation or IRS records, entering an incorrect taxpayer identification number, providing a bank account that does not match the entity, and leaving required representations incomplete. A rejected submission is not a reason to create a second account or pay a third-party “activation” fee. Read the validation message, correct the source mismatch, and resubmit through SAM.gov.
Maintain the registration every year
SAM registrations must be renewed at least annually, and updates should be made sooner when legal name, address, ownership, banking, NAICS codes, points of contact, or size status changes. Put the expiration date on a shared calendar with reminders 90, 60, and 30 days out. Review the whole record during renewal; do not merely click through unchanged fields.
An active registration does not automatically update your certification profiles. Keep your SBA certification records, representations, capability statement, and internal compliance files consistent. Before submitting a proposal, verify that the registration is active, the UEI is correct, and the solicitation's eligibility requirements match your current status.
SAM.gov registration is administrative groundwork, but it directly affects whether an agency can find and award to you. Once your record is active, use saved searches and a qualification process to pursue opportunities that fit your NAICS codes, certifications, capacity, and past performance.
