Do subcontractors need SAM.gov?

Updated September 2026

The FAR conversation and the invoice conversation are different. You can argue about whether a particular clause required a UEI. You cannot argue with a prime who will not put you on an EFT file without one.

When you almost certainly need it

You want to be paid on a federal prime contract, the prime asked for your UEI, or the subcontract says you must maintain an active SAM.gov registration. Register. It is free. Use the readiness checklist so validation does not eat the first month of the job.

When you might not

A purely commercial job with no federal money, or a tiny vendor the prime is paying on a credit card with no flow-down, may never mention SAM.gov. Do not let a registration mill invent a requirement that is not in your subcontract. Read the document you signed.

There is no subcontractor edition

You do not buy a different identifier for “sub” versus “prime.” One legal entity, one UEI, one yearly renewal, still $0. CAGE codes and reps-and-certs live on that same record. A page selling “subcontractor SAM.gov certification” is selling a walkthrough of the free form, or a PDF.

If you later bid as a prime, the same Active record is the one a contracting officer checks. See where opportunities are posted.

What to send the prime

Your legal name as it appears in SAM.gov, the UEI, and a screenshot of Active that you took while signed in — or the public entity view if it shows what they need. Do not send Login.gov passwords. Do not let the prime “register for you” unless that is a person you already pay for compliance and you stay the Entity Administrator.
