SAM.gov Registration and the UEI

SAM.gov registration is the federal government’s entity registry. Registering assigns a Unique Entity ID, the twelve-character code that replaced the DUNS number. Registration requires an identity account, entity validation against authoritative records, core entity data, and annual renewal. Registration is free.

Key takeaways

• SAM.gov registration and the Unique Entity ID cost nothing; third parties charge for both.
• Entity validation, not data entry, is the step that stalls registrations.
• The Unique Entity ID never expires. The registration behind it does.
• Subrecipient reporting may need an identifier only; direct awards need full registration.
• Registration lead time belongs on a standing calendar, not a proposal checklist.

What is the Unique Entity ID and what did it replace?

The Unique Entity ID is a twelve-character alphanumeric code that identifies an entity in SAM.gov. SAM.gov itself issues the identifier, assigning it during entity validation or as part of a full registration (SAM.gov Entity Registration). The Unique Entity ID replaced the DUNS number, a proprietary identifier obtained from a commercial third party.

The change matters beyond nomenclature. Obtaining the government’s required identifier once meant transacting with a private company. The Small Business Administration describes the shift plainly: businesses “no longer have to go to a third-party website to obtain their identifier (DUNS number)” (SBA, Basic Requirements).

The Unique Entity ID travels with the entity permanently and does not expire. Federal agencies must require applicants to include the identifier in every application they submit (2 CFR 25.200), and it flows automatically into application packages once an organizational profile exists. An organization holding a valid Unique Entity ID has not thereby demonstrated that it is registered, a distinction covered further below and treated in more depth in eligibility and organizational readiness.

Who needs a SAM.gov registration, and who needs only a UEI?

Any entity that intends to receive a federal award directly needs a full SAM.gov registration. SAM.gov states the boundary directly: “If you want to apply for federal awards as a prime awardee, you need a registration.” An entity that will not apply directly — for example, one that only needs to be reported as a subawardee — may need only a Unique Entity ID (SAM.gov Entity Registration).

The subrecipient carve-out is narrow but real and worth knowing before an organization spends weeks on a registration it does not need. Under the Uniform Guidance appendix governing entity identifiers, no entity may receive a subaward until it has provided its Unique Entity ID, and “Subrecipients are not required to complete full registration in SAM.gov to obtain a UEI” (2 CFR Part 25). Pass-through entities cannot make the subaward without the identifier, so the requirement is not optional — it is simply lighter.

The rule for full registration is stricter than most applicants assume. Federal agencies must require an applicant to be registered in SAM.gov before submitting an application and to maintain a current and active registration for the entire time it holds an active award or a pending application (2 CFR 25.200). An individual applying as a natural person, unrelated to any business or nonprofit the individual owns or operates, is excepted from the requirement.

How do you register in SAM.gov and get a Unique Entity ID?

SAM.gov registration follows a fixed dependency chain, and the order cannot be rearranged. There are seven stages, each of which must complete before the next can begin:

1. Create a federal identity account. SAM.gov usernames and passwords are managed by the government’s shared identity service, so account creation happens there and returns to SAM.gov to complete a user profile.
2. Choose registration or identifier only. The decision determines everything downstream. Registration supports direct awards and contracts; an identifier alone supports subaward reporting and similar transactions.
3. Enter entity information and pass entity validation. Legal business name, physical address, start year, and state of incorporation are checked against authoritative records. The Unique Entity ID is assigned when validation succeeds.
4. Complete core entity data. Taxpayer identification number, banking information for electronic funds transfer, size and industry classifications, points of contact, and executive compensation questions.
5. Complete assertions and, for contract seekers, representations and certifications. Entities pursuing only financial assistance complete a shorter path than entities pursuing contracts.
6. Clear external validations. Taxpayer identification and commercial and government entity code checks run outside SAM.gov and can return the registration for correction.
7. Register downstream. Grants.gov organizational registration, then any agency-specific system the target program requires.

Stages three and six are the only ones an applicant cannot compress by working faster, because both depend on outside parties. An unsubmitted registration draft also does not wait indefinitely — a draft left untouched is removed, forcing a restart (DOE SAM Registration Guide).

Why does entity validation stall SAM.gov registrations?

Entity validation stalls registrations because it compares self-reported information against independent authoritative records, and a mismatch of any size fails the comparison. Validation confirms the entity’s legal business name, physical address, start year, and state of incorporation (DOE SAM Registration Guide). It is the first step in obtaining a Unique Entity ID and the first step of a registration.

The documentation pattern is consistent even as specific accepted forms change. Proof of name and address comes from documents such as filed articles of incorporation or formation, a secretary of state certificate of filing, the Treasury letter assigning an employer identification number, a state business registry profile, or a utility bill. Proof of start year and state comes from a similar but narrower set. At least one submitted document must carry both the full legal business name and the current physical address, several categories must be no more than five years old, and international documents require a satisfactory English translation (GSA Federal Service Desk, Entity Validation Documentation Requirements).

The rule that produces the most rejections is the exactness rule: submitted documents must show the entity’s information exactly as entered in SAM.gov. A suffix, an abbreviation, a suite number, or a name the organization uses in practice but never filed will fail validation. Validation is also re-triggered by ordinary events — an initial registration, an annual renewal, and any change to legal name or physical address — which means an office move can silently return a long-registered organization to documentary review.

Who holds the Entity Administrator and EBiz POC roles?

SAM.gov registration assigns two role sets that control everything downstream, and both are attached to named individuals rather than to the organization. The Entity Administrator manages the registration record inside SAM.gov. The Electronic Business Point of Contact, designated in SAM.gov and carried into Grants.gov as the EBiz POC, controls who may act for the organization in the application system.

Role continuity is the durable risk. The registration guidance recommends assigning the administrator role to at least one additional person in the organization, and warns that replacing a departed Entity Administrator requires submitting a notarized letter to the Federal Service Desk (DOE SAM Registration Guide). A notarized letter is a multi-day process that cannot be accelerated by urgency.

The EBiz POC controls a specific and time-sensitive power in Grants.gov: assigning the Authorized Organization Representative role, which is the role permitted to submit applications (Grants.gov, Applicant Registration). A common institutional failure follows directly from that design — the EBiz POC is a finance or executive staffer who has left, whose email no longer receives mail, and who is the only person able to authorize a submitter. Assigning backups to both roles, and confirming them at renewal, costs nothing and removes the failure mode entirely.

Why does SAM.gov registration have to be renewed every year?

SAM.gov registration expires on a fixed annual clock and must be renewed to stay active (SAM.gov Entity Registration). Renewal re-triggers entity validation and the external taxpayer and entity-code checks, which is why renewal is not a same-day confirmation but a repeat of the slowest parts of the original process.

An expired registration is the single most common preventable disqualification in federal grant seeking, because it converts an otherwise eligible, well-prepared applicant into an ineligible one on submission day. The Justice Department’s application guide states that an expired registration “can delay or prevent the submission of an application for funding in Grants.gov and JustGrants” and directs applicants to begin registration or renewal well before the deadline (OJP Grant Application Resource Guide).

The structural trap is that nothing visibly breaks when a registration lapses. The Unique Entity ID still resolves, the organizational profile still exists, and the applicant has no reason to suspect a problem until an application is refused. Treating renewal as a standing calendar item with a named owner — rather than a task discovered during proposal production — is the entire fix, and it belongs in the same operating rhythm as a grant readiness assessment.

Is SAM.gov registration free, and what do third parties actually sell?

SAM.gov registration is free. The government’s own entity registration checklist states it without qualification: “SAM.gov is FREE to use. There is no charge to get a Unique Entity ID, register your entity, and maintain your entity registration at SAM.gov” (SAM.gov Entity Registration Checklist). Grants.gov repeats the point for applicants: “It’s free to register” (Grants.gov, Applicant Registration).

Third parties nonetheless sell registration assistance, and some of what they sell is a service while some of it is a fee for a free thing. The General Services Administration addresses both cases directly, noting that some third-party companies offer to help register an entity for a fee, that “Registration in SAM.gov is always free,” and that “any email or website that asks for money, no matter how official it looks, is not a government message or site” (GSA, “Don’t Take the Bait”).

The risk is not only the fee. The Occupational Safety and Health Administration states the consequence of outsourcing the obligation:

“Registration with SAM is free and applicants should not rely on third parties to engage in SAM registration for them. Third parties may misrepresent (intentionally or unintentionally) that they have obtained a SAM registration for the organization when they have not in fact done so. In cases where an applicant does not obtain and maintain an active bona-fide SAM registration, a grant application will be denied even if the applicant relied in good faith on a third party’s representation that an active bona-fide SAM registration was obtained.” — OSHA, “What is the System for Award Management (SAM) and how do I register?”

Free public assistance exists. APEX Accelerators, the federally supported network formerly known as Procurement Technical Assistance Centers, provide no-cost help completing SAM.gov registration (SAM.gov Entity Registration). Separately, Grants.gov maintains guidance on grant fraud, noting that “applying for a grant is completely free” (Grants.gov, Grant Fraud).

How does SAM.gov connect to Grants.gov and agency systems?

SAM.gov sits at the base of a layered stack, and each layer above it depends on the one below. Grants.gov uses SAM.gov to establish organizational authority, so an organization cannot begin applying in Grants.gov until it is registered in SAM.gov (Grants.gov, Applicant Registration). Agency-specific systems then sit above Grants.gov.

Three agency systems account for most of the additional registration work. eRA Commons is the National Institutes of Health applicant and recipient system and requires the Unique Entity ID before an institutional account can be created. Research.gov is the National Science Foundation’s proposal preparation and submission environment. The SBA Company Registry issues the identifier that small business innovation applicants must carry into an SBIR or STTR application. The research funding tracks are covered in research grants at NIH and NSF and SBIR and STTR.

Sequencing across the stack is where lead time accumulates. The National Institutes of Health publishes stated durations for each layer and a headline instruction that captures the compound effect: “Start now! It can take 6 weeks or more to complete the registration process” (NIH SEED, Required Company Registrations). No layer can be started before the one beneath it is active, so the durations add rather than overlap.

What goes wrong with SAM.gov registration?

SAM.gov registration failures are concentrated in a handful of patterns, and every one of them is visible in advance. There are six that account for most missed deadlines:

• Starting registration during proposal production. Registration is a standing quarterly obligation, not a proposal task; a deadline discovered inside a two-week window cannot absorb a multi-week validation.
• Name or address drift. A moved office, a filed amendment, or an informal trade name creates a mismatch that returns the registration to documentary review.
• A departed Entity Administrator or EBiz POC. Both roles attach to individuals, and recovering an orphaned administrator role requires a notarized letter.
• Treating the identifier as proof of registration. The Unique Entity ID does not expire; the registration does, and only the registration confers eligibility.
• Paying a third party and assuming the work happened. A vendor’s assurance is not a registration, and the denial lands on the applicant.
• Ignoring the layers above SAM.gov. An active SAM.gov registration does not create an eRA Commons account, a Research.gov account, or an SBA Company Registry entry.

SAM.gov registration is infrastructure with a maintenance schedule, and organizations that treat it as one-time setup discover the schedule at the worst possible moment. Confirming registration status, role assignments, and downstream accounts on a fixed quarterly cadence removes the entire category, and it is the operational half of grant eligibility.

Frequently asked questions

How long does SAM.gov registration take?

SAM.gov states that registration can take up to ten business days to become active after submission. Grants.gov adds that if information is not available or cannot be verified, completion can take weeks or months. Agency planning guidance is more conservative than either figure; see the current figures above.

Does the Unique Entity ID expire?

The Unique Entity ID does not expire and stays attached to the entity record permanently. The registration behind it expires annually. An organization can hold a valid, resolvable identifier while its registration is inactive, which is precisely why the identifier is not evidence of eligibility.

Do you need SAM.gov registration to be a subrecipient?

No entity may receive a subaward until it has provided its Unique Entity ID, but subrecipients are not required to complete a full SAM.gov registration to obtain that identifier. An entity that expects to receive direct federal awards later should register fully rather than rely on the lighter path.

What happens if a SAM.gov registration expires mid-award?

Federal agencies must require recipients to maintain a current and active registration throughout the time they hold an active award. A lapse during an award can interrupt payment processing and blocks new applications, and correcting it restarts validation rather than resuming where the record left off.

Can someone else register your organization in SAM.gov for you?

Third-party services exist and some are legitimate, but the obligation and the consequence remain with the applicant. Federal guidance warns that a third party may represent that a registration was obtained when it was not, and that an application will be denied regardless of the applicant’s good faith.

Why does entity validation ask for documents when the entity already has an EIN?

An employer identification number confirms a taxpayer record, not a legal name and physical address at a point in time. Entity validation confirms that a specific legal entity exists, is unique, and is located where it claims to be, which requires filed or issued documents rather than a tax identifier alone.
