How to Register on SAM.gov: A Step-by-Step Guide

Updated July 1, 2026 4 min read

You do not have to pay anyone to register your business on SAM.gov. It is free, directly at sam.gov, every time. What it is not is simple. The registration touches five separate systems (IRS records, DLA's CAGE database, entity validation, reps and certs, and banking) and most of the pain people report online is not SAM.gov being slow. It is one of those systems disagreeing with another.

Here is the order it actually happens in, and where people get stuck.

Step 1: Get your EIN sorted first

Your Employer Identification Number has to match IRS records exactly: legal name, address, everything. This is the single biggest source of delay later, so confirm it before you touch SAM.gov at all.

Step 2: Get your UEI

The Unique Entity Identifier replaced the old DUNS number. You get it directly inside SAM.gov as the first step of registration, not from a third party. If a site asks you to pay for a UEI, it is not a real government process.

Step 3: Entity validation

This is where SAM.gov checks your legal name, physical address, and EIN against IRS records. If everything matches, it clears automatically. If it does not, you get pulled into a manual review. According to GSA's own guidance, a clean submission takes up to 10 business days to become active (GSA, "Register your business"). A mismatch does not just cost you a few days. It is widely reported to add anywhere from several days to a few weeks, because it moves into a manual queue instead of an automated pass.

Step 4: Your CAGE code

Your CAGE (Commercial and Government Entity) code gets assigned by the Defense Logistics Agency as part of the same registration, generally inside that same window, longer if DLA needs more information from you. You do not apply for it separately.

Step 5: NAICS and PSC codes

Pick the codes that actually describe what you sell or do. These determine what opportunities you can be found under, so do not just pick one and move on. Most businesses register under several.

Step 6: Reps and certifications

The section everyone skims. It asks you to represent things about your business (size status, ownership, whether you are a small business under your NAICS codes) that contracting officers rely on. Read every question. Getting this wrong is a compliance problem later, not just paperwork now.

Step 7: Banking (EFT) details

Standard direct-deposit information for how the government pays you once you are awarded work.

Step 8: Submit, then wait on the system, not on you

Once everything above is entered, submitting takes minutes. What happens after is largely out of your hands: SAM.gov validates, DLA assigns your CAGE, and you go active. The FAR was actually amended in August 2025 to clarify that your registration only has to be active at two points: when you submit an offer and when you are awarded. A short lapse in between does not automatically disqualify you (FAR 52.204-7), though you still need to renew annually to avoid an actual lapse.

We are not SAM.gov, are not affiliated with the U.S. government, and are not a registrar. SAM.gov registration is always free at sam.gov. We provide preparation assistance only.

What actually costs you time

Not SAM.gov's queue. The data mismatch. A business name that does not match the IRS letter for letter, an address format entity validation does not recognize, a missing formation document. Each one restarts a manual review, not the whole 10 days, but a fresh wait behind it. Getting every field right on the first pass is the one thing you actually control.

If you want a structured version of this checklist that tracks what is missing as you go, our free readiness check walks the same eight steps and flags what is incomplete before you submit.

The last step in that sequence, reps and certs, gets skimmed more than any other, and it shouldn't be. Here's what that section actually commits you to once you hit submit.
