You cannot receive a federal contract without an active SAM.gov registration. It is not optional, not something you can complete after winning a bid, and not something a contracting officer can waive. The System for Award Management is the single authoritative database for every entity doing business with the US federal government — and registration is the first mandatory step before you can submit a proposal on any SAM.gov-listed opportunity.
This guide walks you through every screen, every field, and every common rejection point. Plan for 5–7 business days minimum from submission to active status. Start before you need it.
Gathering these before you open SAM.gov saves you from abandoning registration midway. The form does not save progress cleanly across sessions once certain validation tokens expire.
SAM.gov registration is completely free at sam.gov. The DUNS number system was retired on April 4, 2022 and replaced by the UEI system. Dozens of third-party sites charge USD 299–999 to "register" or "activate" your SAM.gov account. These are unnecessary intermediaries at best and outright scams at worst. Always go directly to sam.gov.
The UEI is a 12-character alphanumeric identifier that permanently identifies your business across all federal procurement and grant systems. It replaced the DUNS number and is now required on every contract, invoice, and federal form.
You need a Login.gov account first — see Step 2. Once signed in, your SAM.gov workspace appears. New registrants: click "Get Started" under "Register Entity."
The system validates your address against USPS in real time. The most common cause of UEI failure is an address format mismatch. Use the USPS address standardisation tool at usps.com/zip4 to pre-verify your format before entering it here.
SAM.gov runs your EIN against the IRS e-Verify system. This can take 1–3 business days if the IRS system is under load. Do not attempt to create a duplicate entity during this waiting period — doing so flags your entity for manual review and adds 5–10 days to activation.
Once IRS validation clears, SAM.gov assigns your UEI and sends an email to your Login.gov address. Your UEI is now permanent — it does not change if you renew, update, or lapse. Save it with your business records.
Your UEI is the lookup key in FPDS-NG (Federal Procurement Data System — Next Generation), where all federal contract awards are publicly searchable. Once your registration is active, contracting officers can pull your award history by UEI during source selection. A complete SAM.gov profile with accurate NAICS codes and size certifications functions as your federal procurement resume — first impressions matter before you ever submit a proposal.
Login.gov is the US government's shared authentication service, mandatory for SAM.gov access since 2022. Your Login.gov credentials are separate from any other government portal you may have used (grants.gov, beta.sam.gov, etc.).
Use your primary business email. All SAM.gov renewal reminders, contract notifications, and account alerts are sent here. Use an email address with long-term stability — not a personal Gmail you might abandon.
Options: authenticator app (Google Authenticator, Authy — recommended), SMS text message, or physical security key. Use an authenticator app rather than SMS where possible — SMS 2FA is vulnerable to SIM-swapping attacks, and SAM.gov account takeovers to redirect EFT payments do occur.
Login.gov displays a one-time 16-character personal key during setup. This is the only recovery method if you lose access to your 2FA device. Store it in a password manager or a physically secure printed document — not in email or cloud notes.
Core Data is the largest section of SAM.gov registration. It covers legal identity, financial setup, and business classification. Every field marked with a red asterisk is mandatory — SAM.gov will reject incomplete submissions without always specifying which field caused the failure.
| Field | What to enter | Common error |
|---|---|---|
| Legal Business Name | Exact match to IRS EIN letter — include "Inc.", "LLC", "Corp." as officially filed | Abbreviated name causes IRS mismatch and delays validation by 3–5 days |
| DBA (Doing Business As) | Trade name if different from legal name — optional but recommended if you operate under a brand | Leaving blank when you invoice under a different name causes confusion on contract documents |
| Physical Address | USPS-standardised format — use "STE" not "Suite", "DR" not "Drive" | Non-standardised format causes real-time USPS validation failure; entire section blocked |
| Business Start Date | Date business was legally registered with your state — not founding date | Using incorporation date instead of state registration date causes IRS cross-reference mismatch |
| Fiscal Year End Close | Month your fiscal year ends — "12" for December is standard for most small businesses | Leaving as default "01" (January) creates incorrect financial year references in FPDS |
| Number of Employees | Total headcount including part-time — this determines size standard calculations | Understating headcount can constitute a misrepresentation if challenged during contract award |
The EFT section configures how the government pays you. A US business bank checking account is required. International businesses without a US account can request a payment-by-check waiver, but this significantly delays payment processing.
Federal payment fraud most commonly occurs when attackers gain access to a SAM.gov account and update the EFT section to redirect payments to a fraudulent account. The government does not reimburse misdirected payments due to compromised credentials. Enable Login.gov 2FA (mandatory), never share credentials, and audit your EFT details quarterly. If you receive an unexpected SAM.gov change notification email, log in immediately and verify nothing was altered.
Assertions determines which contracts you can compete for — including set-aside contracts reserved exclusively for small businesses. This is one of the highest-leverage sections in your entire SAM.gov registration.
Business category codes (NAICS — North American Industry Classification System) are 6-digit numbers. You select one primary code (your main business activity) and can add up to 10 additional codes. Your primary NAICS code determines your small business size standard.
| Supplier category | NAICS code | Size standard |
|---|---|---|
| IT hardware resale / distribution | 423430 | $35M revenue |
| IT consulting and custom software | 541512 | $30M revenue |
| Staffing — temporary general | 561320 | $35M revenue |
| Medical / dental supplies wholesale | 423450 | $35M revenue |
| Office supplies wholesale | 424120 | $35M revenue |
| Management consulting | 541611 | $21.5M revenue |
| Technical training / vocational | 611519 | $12M revenue |
| Commercial construction | 236220 | $45M revenue |
| Janitorial / facility services | 561720 | $22M revenue |
| Security services | 561612 | $22M revenue |
Add every NAICS code that legitimately describes your capability. Contracting officers search SAM.gov by NAICS when identifying potential sources for market research — a narrow code list means missed visibility. Do not add codes for services you cannot actually deliver; this creates problems during past performance reviews in CPARS (your official government performance report card) and can be grounds for protest.
A federal contract issued as a small business set-aside under FAR 19.502-2 typically attracts 4–8 competitors. The same contract issued as full and open competition typically attracts 15–40 bids. If you qualify for any set-aside category, certifying it in SAM.gov Assertions may be the single highest-ROI action in your government contracting strategy. BidClarity's scoring engine identifies set-aside eligibility for each opportunity and factors it into your match score automatically.
This is the most legally significant section of your SAM.gov registration. Under FAR Part 4.1201 (federal acquisition regulations — the rulebook governing US federal government purchasing), you are making formal certifications to the US government. False or inaccurate certifications carry civil and criminal liability under the False Claims Act (31 U.S.C. § 3729), which allows the government to recover three times the amount of any resulting loss plus civil penalties of USD 13,000–27,000 per false claim.
Most small businesses can accept the standard pre-populated representations. The system defaults to "No" on all conflict-of-interest and debarment representations, which is correct for most entities. If you are uncertain about any certification, consult a procurement attorney before submitting — the cost of a legal review is far lower than the cost of a False Claims Act investigation.
SAM.gov requires two mandatory points of contact. Both must have Login.gov accounts.
If the person designated as Entity Administrator leaves your organisation, update SAM.gov immediately. Lapsed POC contact details are the leading cause of missed renewal reminders and unintended registration expiry — which can disqualify you from contracts mid-competition.
After submitting, SAM.gov runs a series of automated validations. Understanding the sequence helps you diagnose delays.
| Validation check | Typical time | If it fails — action required |
|---|---|---|
| IRS EIN / TIN cross-validation | 1–3 business days | EIN does not match IRS records — verify against your original IRS SS-4 letter; do not resubmit without correcting |
| USPS physical address validation | Instant | Address not in USPS delivery database — use usps.com/zip4 to find standardised format |
| SAM exclusions and debarment check | Instant | Entity flagged on exclusions list — requires legal review; contact SAM.gov help desk at 866-606-8220 |
| CAGE Code assignment | Within 24 hours of IRS clearance | Duplicate entity detected — contact SAM.gov Federal Service Desk for merge resolution |
| Final registration activation | 1 business day after CAGE assigned | Email notification sent to Entity Administrator POC email address |
Until you receive the activation confirmation email, your entity is not visible to contracting officers and you are ineligible for contract awards. Do not submit proposals before activation.
SAM.gov registrations expire exactly 365 days after activation. Renewal reminders are sent at 60 days, 30 days, and 15 days before expiry to your Entity Administrator email. The renewal process takes 1–7 business days — the same as initial activation — so begin renewal at the 30-day reminder at the latest.
If your registration expires:
There is no grace period after expiry. A contracting officer running a SAM.gov eligibility check on award day who finds your registration expired is legally required under FAR 4.1103 to exclude you from the award. This has happened to long-established contractors on contracts they were otherwise positioned to win. Set a recurring calendar reminder 90 days before your expiry date — earlier than the SAM.gov reminders — so you have buffer time if the IRS validation is slow.
If your business operates across the US-Canada border or is considering expanding into Canadian federal procurement, these are the key structural differences between the two systems.
| Factor | SAM.gov (US Federal) | CanadaBuys (Canada Federal) |
|---|---|---|
| Registration system | sam.gov — free, self-serve | Supplier Registration Information (SRI) — free via buyandsell.gc.ca |
| Entity identifier | UEI — 12-character alphanumeric, assigned by SAM.gov | Business Number (BN) — 9-digit, issued by CRA (Canada Revenue Agency) |
| Industry codes | NAICS — 6-digit, shared US/Canada/Mexico standard | GSIN — 7-character Goods and Services Identification Number, Canada-specific |
| Small business set-asides | Extensive programme under FAR Part 19 — 8(a), HUBZone, SDVOSB, WOSB, SBA set-aside | Limited — Procurement Strategy for Indigenous Business (PSIB) and Supplier Diversity pilot; no broad equivalent to SBA set-asides |
| Registration expiry | Annually — exactly 365 days, requires active renewal | No fixed expiry — update when business information changes |
| Payment setup at registration | EFT banking details required at registration | Set up per-contract with the issuing department via Direct Deposit Enrolment form |
| Past performance tracking | CPARS — automated, mandatory for contracts over $150,000; visible to all federal agencies | Vendor Performance Management System (VPMS) — less automated, limited cross-agency visibility |
| Opportunity database | SAM.gov Contract Opportunities — all federal solicitations above $25,000 required to post | CanadaBuys — federal solicitations above $25,000 CAD; provincial contracts on separate portals |
Registration activates — what now? The most common mistake is to stop here and wait for contracts to appear. Active procurement intelligence is what converts registration into revenue.
sam.gov → Contract Opportunities → filter by NAICS code, set-aside type (Small Business if applicable), and active status. Set up SAM.gov email alerts for new postings matching your NAICS codes — these are free and send daily digests of new solicitations.
DSBS is a free supplemental database that contracting officers use for market research before issuing a formal solicitation. Completing a DSBS profile with specific capability keywords increases your visibility for pre-solicitation outreach — opportunities that never formally appear on SAM.gov.
As revenue grows, you may cross the size standard threshold for your primary NAICS code. Update your Assertions section before you exceed it — not after. Misrepresenting small business status in a bid is a False Claims Act violation with potentially ruinous consequences.
SAM.gov email alerts only cover SAM.gov. Federal and international procurement opportunities exist across 37+ portals — World Bank, UNGM, TED Europa, CanadaBuys, provincial databases, AusTender, GeBIZ, and more. Monitoring them manually across your specific NAICS codes is a full-time job. BidClarity does this automatically — scoring every match against your profile and delivering only your highest-fit opportunities each morning.
