How to Register on SAM.gov: Step-by-Step Guide for Contractors (2026)

If you want to win federal contracts, there is exactly one gate you must walk through first: an active registration in SAM.gov, the government's System for Award Management. No SAM registration, no federal award — it's that binary. Agencies literally cannot obligate money to a business that isn't active in SAM at the time of award.

The good news: registering is completely free, and if your paperwork is in order, the form itself takes an afternoon. The bad news: the process is bureaucratic, small mismatches in your business name or address can stall you for weeks, and the moment you register, a cottage industry of third-party firms will start calling to "help." This guide walks through the whole process in plain English — what to prepare, each step in order, where registrations get stuck, and what to do after you're approved.

Why SAM.gov registration is mandatory (and free)

SAM.gov is the federal government's master vendor database. Registering does three things at once: it establishes your business as a legal entity the government can pay (via electronic funds transfer), it records your certifications and representations so contracting officers don't have to collect them for every contract, and it assigns you the identifiers — a Unique Entity ID and a CAGE code — that follow your business through every federal solicitation, award, and invoice.

Two warnings before you type a single field:

• Never pay anyone to register you. SAM.gov registration and renewal are free, forever. Dozens of private companies with official-sounding names charge $300–$600 to "process your SAM registration" or send alarming "your registration is expiring — renew now" letters. They have no special access; they fill out the same free form you can. Some are merely overpriced; others are outright scams. The only official site is sam.gov — note the .gov.
• Expect spam after registering. Unless you opt out of public search display, your business name, address, and points of contact become publicly visible, and marketers scrape it. A wave of calls and emails offering "GSA Schedule help" and "guaranteed contracts" is normal. It doesn't mean you were breached — it means you're in a public database. Consider using a dedicated phone number and email for your SAM points of contact.

Before you start: the 15-minute checklist

Most SAM registration horror stories trace back to starting the form before the underlying records agree with each other. Gather and verify these first:

1. Your exact legal business name and physical address. This is the single most important item. The name and address you enter must match your state incorporation records and your IRS records character for character. "Acme Solutions LLC" vs. "Acme Solutions, L.L.C." or "Suite 200" vs. "Ste 200" is enough to trip validation. Decide on the canonical version now, and if your IRS and state records disagree, fix that before registering. P.O. boxes don't count as a physical address.
2. Your EIN (Taxpayer Identification Number) from the IRS. Sole proprietors can use an SSN, but an EIN is strongly recommended — it's free from the IRS and keeps your SSN out of government systems. If you just got your EIN, wait about two weeks before registering so it propagates through IRS systems; brand-new EINs are a classic cause of failed TIN validation.
3. Bank account and routing numbers. The federal government pays by electronic funds transfer (EFT) only. You'll enter your bank details, plus a remittance contact, in the registration.
4. Your NAICS codes. These industry codes tell the government what you sell and drive which opportunities you're matched to. Pick a primary code and a handful of secondary ones before you start — our NAICS codes guide walks through choosing them well.
5. A Login.gov account. SAM.gov sign-in runs through Login.gov, the government's shared identity service. If you don't have an account, you'll create one in step one below — have your phone ready for two-factor authentication.

Optional but useful: your company's start date and fiscal year end, average annual receipts and employee count for the last few years (needed for small-business size questions), and any socioeconomic statuses you may claim (woman-owned, veteran-owned, HUBZone, 8(a), etc.).

Step-by-step: registering your entity

Step 1 — Create your Login.gov account

Go to sam.gov, click "Sign In," and you'll be handed off to Login.gov. Create an account with a work email you'll keep long-term, set a strong password, and add at least one two-factor method (an authenticator app is more durable than SMS). This account belongs to you, the person — not the business — so use an email you control even if staff changes later.

Step 2 — Start the entity registration and get your Unique Entity ID

Once signed in, choose "Get Started" under entity registration and select the full registration for "All Awards" (there's a lighter "Unique Entity ID only" option, but it does not make you eligible for contract awards — you want the full registration). Early in the process, SAM validates your legal name and address against its entity validation service and issues your Unique Entity ID (UEI) — a 12-character identifier that replaced the old DUNS number in 2022. You no longer need anything from Dun & Bradstreet; the UEI is generated by SAM.gov itself, free. If validation matches your business on the first try, this takes minutes. If it doesn't, see the documents section below.

Step 3 — Core Data

This is the heart of the registration: your legal name, physical and mailing addresses, start date, fiscal year end, EIN, and your TIN consent (authorizing SAM to validate your EIN/name combination with the IRS), plus your EFT banking details and executive compensation questions. Again: enter your business name and EIN exactly as they appear on IRS records (your CP-575 EIN confirmation letter is the reference). This section is where the IRS match happens, and a mismatch here is the number-one source of multi-week delays.

Step 4 — Assertions

Assertions describe what you sell and how big you are: your NAICS codes (mark one as primary), optional Product Service Codes, and your size metrics — average annual receipts and average number of employees. SAM uses these numbers against the SBA's size standards to determine, per NAICS code, whether you count as a small business. That flag matters enormously: it controls your eligibility for small-business set-asides, which are a large share of winnable federal work for new contractors.

Step 5 — Representations & Certifications

"Reps & Certs" is a long questionnaire of yes/no legal representations pulled from the Federal Acquisition Regulation: whether you're debarred, whether you have delinquent federal taxes, socioeconomic statuses you claim, compliance with various statutes. Answer honestly and carefully — these are certifications with legal weight, and contracting officers rely on them for every award. Most small businesses can get through this section in 30–45 minutes; when in doubt on a question, your local APEX Accelerator (formerly PTAC) offers free help.

Step 6 — Points of Contact, then submit

List your points of contact — at minimum an Electronic Business POC and a Government Business POC (they can be the same person). These names and emails are who agencies contact about bids and payments, and who receives renewal reminders, so use addresses that are actually monitored. Review everything and submit.

Step 7 — The waiting period

After submission, two validations run behind the scenes: the IRS TIN match (your EIN + legal name against IRS records) and CAGE code assignment by the Department of Defense. Together these typically take anywhere from three business days to about two weeks. You'll get an email when your registration goes Active — and only then are you eligible for awards. Common causes of delay: a name/address that doesn't match IRS or state records (by far #1), a brand-new EIN that hasn't propagated, and unanswered follow-up emails from the CAGE team — watch your inbox and spam folder for anything from DLA/CAGE and respond fast.

When the automated match fails: entity validation documents

If SAM's entity validation service can't confirm your legal name and physical address automatically, you'll be asked to create a help ticket and upload documentary proof. Acceptable documents must show the exact name and address you entered and generally must be recent (or show your start date). Commonly accepted:

• State-issued articles of incorporation/organization or a certificate of good standing (best for proving the legal name)
• A utility bill, bank statement, or lease in the business's name (best for proving the physical address)
• IRS letters such as your CP-575 EIN assignment notice

Submit documents that agree with each other and with what you typed. The review is done by humans, tickets are processed in order, and each rejected round adds days — so make the first submission clean. If your documents show a different name or address than you entered, change the registration to match the documents, not the other way around.

After approval: keeping your registration alive

Getting to Active isn't the finish line — SAM registration is a subscription you renew with attention rather than money:

• Renew every 365 days. Registrations expire one year after activation or last renewal. If yours lapses, you drop out of eligibility: agencies can't make awards to you, and payments on existing contracts can hang up. Renewal is free and usually quick, but it re-runs validations — so don't start it the week a proposal is due. Calendar it 60 days ahead, and treat any paid "renewal service" letter as junk mail.
• Keep banking and POC data current. Wrong EFT details mean the government literally can't pay you; stale POC emails mean you miss renewal notices and agency questions. Update SAM whenever your bank, address, or people change.
• Decide on public search visibility. SAM lets you opt out of public search display. Opting out cuts down scraping and spam, but it also means primes searching SAM for subcontractors and teaming partners can't find you. Many contractors accept visibility as the cost of being findable; if you opt out, agencies and existing partners can still see your record.

Registered on SAM — now where are the bids?

Here's the part most guides skip: SAM.gov registration makes you eligible; it doesn't bring you work. SAM's Contract Opportunities section lists federal solicitations — and only federal. The far larger universe of state, county, city, school district, and transit authority procurement never touches SAM.gov. Every state runs its own portal, and tens of thousands of local agencies post bids on their own websites. A contractor in Albany or Atlanta who watches only SAM.gov is blind to most of the public-sector spending happening within driving distance — browse New York bids or Georgia bids and you'll see how much activity exists that federal-only searchers never encounter.

SAM's search interface is also, charitably, dated — noisy results, crude filtering, and alerts that bury the relevant in the irrelevant. That's the gap BidsNexus exists to close: we aggregate federal opportunities and state and local bids into one search, match them to your NAICS codes and keywords, and email you when new opportunities fit — so registering on SAM is step one of a working pipeline, not a dead end. For the full picture of where bids hide and how to build a repeatable system for finding them, read our companion guide, How to Find Government Bids and RFPs.

Frequently asked questions

How long does SAM.gov registration take?

The form itself: one to three hours with documents in hand. Activation after submission: typically a few business days to two weeks for IRS validation and CAGE assignment. If you're routed to manual entity validation over a name or address mismatch, budget several weeks. The practical advice: register at least a month before you intend to bid on anything federal.

Does it cost anything?

No. Registration, your Unique Entity ID, your CAGE code, and annual renewal are all free. Anyone charging you for these is a middleman at best. (Paying a consultant for genuinely optional help — say, strategy on Reps & Certs — is your call, but the registration itself never requires payment.)

What's a CAGE code?

A five-character Commercial and Government Entity code assigned by the Department of Defense during your registration. It identifies your specific business location across federal contracting and payment systems. You don't need to do anything to get it — it's issued automatically before your registration goes Active.

Do I need SAM registration for state and local bids?

Generally no — states and localities run their own vendor registrations, and most of their bids never appear on SAM.gov. Exceptions exist (some agencies check federal exclusion lists, and federally funded state projects may require it), so an active SAM registration is worth keeping regardless. But to actually see state and local opportunities, you need to look beyond SAM — that's what our bid search is for.

The bottom line

SAM.gov registration is free, mandatory for federal work, and very doable in a week or two if you prepare: make your legal name and address consistent across IRS and state records, have your EIN, bank details, and NAICS codes ready, and respond quickly to any validation follow-ups. Then renew every year without fail. And once you're Active, remember that eligibility isn't visibility — pair your registration with a bid-finding system that watches federal, state, and local sources so the opportunities come to you.
