SAM.gov Registration for Contractors, Step by Step (2026)

To bid federal construction work, register your company in SAM.gov. You get a free Unique Entity ID, then complete the entity registration with your legal name, address, tax ID, bank details, NAICS codes and certifications. A CAGE code is assigned during review. Plan for at least two weeks before your first bid, and renew every 365 days.

Federal work is a good market for many contractors, but nobody can be awarded a contract without an active SAM registration. Here is the order I would do it in.

What do you need before you start?

Item Where it comes from
Legal business name and physical address Must match your IRS records exactly
Taxpayer Identification Number (EIN) IRS
Bank account and routing number For electronic payment
NAICS codes Your trades, for example 236220 for commercial building
Point of contact People who can manage the registration
Login.gov account Required to sign in to SAM.gov

Most delays come from a name or address that does not match the IRS record exactly, so check that first.

How do you register, step by step?

  1. Create a Login.gov account and sign in to SAM.gov.
  2. Get a Unique Entity ID (UEI). The 12-character UEI replaced the DUNS number in April 2022 and is issued inside SAM.gov at no cost.
  3. Start the entity registration and choose that you want to bid on federal contracts, not only grants.
  4. Enter core data: legal name, address, EIN, banking and points of contact.
  5. Add assertions: your NAICS codes, size metrics and the product and service codes you sell.
  6. Complete representations and certifications. These replace much of the paperwork that used to go with each bid, so read them carefully.
  7. Submit and wait for validation. A CAGE code is assigned during review for US entities.

How long does it take, and what does it cost?

Registration in SAM.gov is free. Sites that charge a fee are optional services, not the government. Activation commonly takes up to 10 business days after you submit, and longer if the IRS or address check fails, so start well before a bid due date.

How do you keep the registration active?

A registration expires 365 days after you submit it. If it lapses, your UEI and CAGE code stay the same, but you cannot be awarded until it is active again. SAM.gov sends reminders before expiration; put the renewal date in the same calendar as your bid due dates.

She fills in bid forms from your company profile for your team to review and sign; she does not submit bids for you.

Frequently asked questions

Is SAM.gov registration free? Yes. The UEI, the registration and the yearly renewal are free on SAM.gov.

Do subcontractors need SAM registration? Usually not to work under a prime contractor, but some primes and some programs require it. To bid federal work directly, you need it.

What happens if my registration expires during a bid? You can still be found in SAM, but you cannot be awarded until the registration is active again, so renew early.
