How to Register on SAM.gov: Complete 2026 Guide

SAM.gov registration is the single gate every U.S. federal contractor must pass through. Without an active SAM.gov record and a valid Unique Entity ID (UEI), you cannot be awarded a federal contract, grant, or cooperative agreement — full stop. The process is free, takes about 7–10 business days end to end in most cases, and has a reputation for being frustrating mostly because of avoidable rejection reasons.

This guide walks through every step in the order you will encounter it, calls out the traps that send registrations back for correction, and tells you exactly what documents to have on hand before you start.

What SAM.gov is (and what it replaced)

SAM.gov — short for the System for Award Management — is the consolidated registration and solicitation system run by the General Services Administration. It replaced a group of older systems: CCR (Central Contractor Registration), ORCA, EPLS, and FedBizOpps. Today SAM.gov serves three functions for contractors:

1. Entity registration — the profile that makes you eligible to receive federal awards.
2. Exclusions database — the government-wide list of suspended and debarred entities.
3. Contract opportunities — the public search interface for federal solicitations (the old FBO).

You interact with all three, but the registration is what this guide covers.

Step 1: Create a Login.gov account

Everything at SAM.gov is accessed through Login.gov, the government's single sign-on platform. If you already have Login.gov from another federal service (IRS, USPS Informed Delivery, etc.) you can reuse it. If not, create one at login.gov with your business email address, a strong password, and two-factor authentication. Use an email that will persist — you will come back to this account annually to renew.

Step 2: Begin entity registration at SAM.gov

Sign in at sam.gov and click Get Started. Select Register Entity. When asked what you want to do, choose All Awards unless you only need to apply for federal financial assistance (grants/cooperative agreements).

You will then be guided through four main sections:

• Core Data
• Assertions
• Representations and Certifications
• Points of Contact

Step 3: Complete entity validation

Entity validation is the step most new registrants stumble on. SAM.gov uses a validation service (currently Dun & Bradstreet via the Ensemble program) to confirm that your legal business name, physical address, and start-of-business date match authoritative records.

If your entity is already in the validation database and everything matches, validation is instant. If it is not, you will be asked to upload documentation. Common accepted documents include:

• Articles of Incorporation or Certificate of Formation
• IRS EIN assignment letter (CP 575) or a recent 147C letter
• A recent utility bill or bank statement at the physical business address
• State business license

Validation results usually come back in 3–5 business days. When validation completes you are assigned a Unique Entity ID (UEI) — a 12-character alphanumeric identifier that replaces the old DUNS number. Your CAGE code is assigned in parallel by the Defense Logistics Agency.

Step 4: Fill out Core Data

Core Data is where you describe the business. Key fields:

• Business type codes — select every one that applies (e.g., "For-Profit Organization," "Limited Liability Company," "Small Business Administration (SBA) Small Disadvantaged Business").
• NAICS codes — enter every NAICS code your business performs. You can enter up to 10. Mark one as primary. The primary should be the code that generates the largest share of your revenue. You can always add more later.
• Goods and services (PSC) codes — optional but strongly recommended; PSC codes help contracting officers find you for product/service-specific opportunities.
• Financial information — banking details for electronic funds transfer (EFT). The name on the account must match the legal business name exactly.

Step 5: Assertions and Reps & Certs

Assertions are business-fact declarations — annual revenue, employee count, whether you sell on a GSA Schedule, whether you export, and so on. They drive your automatic size certification and socioeconomic eligibility calculations.

Representations and Certifications are the legal equivalent of reading and signing the fine print. Dozens of FAR clauses ask you to certify specific facts (e.g., FAR 52.204-26 covers Covered Telecommunications Equipment). The system pre-populates your answers based on what you entered in Core Data — but you must review every single certification. Click through carefully. A false certification is a False Claims Act violation.

Step 6: Submit and wait

Once every section is complete, submit for processing. The IRS TIN match and the CAGE validation each take 2–5 business days. Most complete registrations activate in 7–10 business days. You can check status anytime from your SAM.gov workspace.

Common rejection reasons (and how to fix them)

After a decade of watching SAM.gov rejections, the same short list accounts for the vast majority of problems:

1. Name mismatch. The exact legal name on your documents does not match what you typed. Fix: pull your EIN assignment letter (CP 575) and copy-paste from there.
2. Address mismatch. The physical address on validation documents is different from what you entered. PO boxes are not accepted as a physical address.
3. Incorrect start-of-business date. Use the date on your incorporation/formation document, not the day you started doing business in practice.
4. Missing notarized letter. For new registrations, an entity administrator notarized letter is no longer required for most filers, but if you are appointing a new administrator on an existing record you still need one.
5. Wrong NAICS primary. If you realize your primary NAICS has the wrong size standard for a solicitation, you can change it — but not after you have submitted a proposal under that solicitation.

After activation: what to do

• Create a capability statement that lists your UEI, CAGE, and NAICS codes, and distribute it to contracting officers and prime partners. See our guide on how to build a capability statement.
• Register on DSBS — the SBA's Dynamic Small Business Search. Many small-business specialists search DSBS before they search SAM.gov.
• Subscribe to opportunities — save searches on SAM.gov for your NAICS and PSC codes. Or use FedProc's intelligent matching to score opportunities against your profile automatically.
• Calendar your renewal. SAM.gov registration expires 365 days after activation (or the last update). Renew 30 days before expiration; a lapsed registration can cause you to be declared non-responsible and lose award opportunities mid-evaluation.

Key takeaways

• SAM.gov registration is free. Never pay a third party who claims they must register you.
• Accuracy beats speed. Every day you spend getting documents right saves a week of rejection-fix rework.
• UEI replaced DUNS in April 2022. If your documents still reference DUNS, update them.
• Renew annually — without fail.

If you are registering for the first time, start with entity validation today and plan for your registration to be active inside two weeks. Once you are active, the real work — finding and winning the right opportunities — begins.
