Registering in SAM.gov and getting your UEI

Free, mandatory, and the step that gates everything else. Plus the login trap that catches everyone.

SAM.gov is the federal government's vendor registry. No registration, no UEI. No UEI, no certification, no bidding, and no federal grants either. It is free and it is the first thing to do.

SAM.gov registration is free. Services charging $500 to $1,500 to do it for you are legal but they are selling convenience, not access. The government never charges for this.

What you need before you start

The name and address must match your IRS and state filings character for character. "St" versus "Street" is enough to bounce a registration and cost you a week.

The login trap

SAM.gov does not manage its own passwords. Signing in goes through Login.gov, so a password or code failure is a Login.gov problem and has to be fixed there, not on SAM.gov. This confuses almost everyone the first time.

How long it takes

GSA says to allow at least ten business days for a registration to go active, and longer if they come back asking for documentation. Answer any request the day it arrives.

Keeping it alive

You must renew every 365 days. An expired SAM registration silently invalidates your certification eligibility and drops you out of the searches contracting officers use. Put the renewal date in your calendar the day you are approved.
