How to register your business in SAM.gov

Why SAM registration comes before any federal offer

You register before you offer, not after you win. Federal rules require offerors to be registered in SAM at the time an offer or quotation is submitted.

That timing catches businesses every year. A bid written over weeks can become unawardable in the last hour because the registration was still processing. Register when you start looking, not when you find something worth bidding on.

Maine's own state system is separate. If the work you want is state work, the Maine vendor registration guide is the one to follow, and the two systems do not share records.

The difference between a Unique Entity ID and a registration

The Unique Entity ID is an identifier. A registration is permission to be a federal contractor. They are not the same step.

SAM.gov lets you request a Unique Entity ID on its own, without completing registration. That route exists for sub-awardees and similar roles. It does not let you apply directly for federal awards.

Choose Register Entity during the process and the Unique Entity ID gets assigned during registration itself. If you only need the ID, take the shorter route. If you intend to bid as a prime, you need the full registration.

SAM.gov assigns a Unique Entity ID during entity registration, and an ID obtained without registering does not allow applying directly for federal awards. — SAM.gov, U.S. General Services Administration, retrieved 2026-09-29

The four stages of a SAM registration

SAM.gov frames registration in four stages: about registration, setting up a SAM.gov account, preparing your data, and getting started.

The account runs through login.gov, so that step happens before any entity data is entered. The data preparation stage is where most of the work sits. You are matching your legal business name and physical address to official records.

A downloadable Entity Registration Checklist exists to help gather what the stages ask for. Download it first, fill it in, and the online process becomes a transcription exercise instead of a scavenger hunt.

Free help exists, and it is not a paid middleman

APEX Accelerators, the program formerly known as PTACs, helps businesses complete SAM registration at no charge. The referral appears on SAM.gov's own pages, which is the right place to find it.

Their help covers more than the form. They also counsel on whether a contract is worth pursuing. For a first federal bid, that judgment is worth as much as the registration itself.

Where your entity stands right now can be checked without logging in, through the Check Entity Status function on SAM.gov. Use it before assuming a lapse or a processing delay.

The 365-day renewal clock

An active registration must be renewed every 365 days. Updates can be made at any time, but renewal is the action that keeps the record alive.

A lapsed registration behaves like no registration at the moment an offer is submitted, which is exactly the failure the submission rule punishes. Put the renewal date in the same calendar as your Maine filings, because nothing else will remind you.

The state-side counterpart to this clock is the Maine vendor account, which has no published expiry but still needs attention when contacts and commodity codes change. If your entity is brand new, the structure it registers under is covered in the business structure page.
