SAM.gov registration is free — here's the official path

Registering, renewing, or updating your business in SAM.gov costs $0. The government keeps it free, every time. The official site is https://sam.gov — look for the .gov ending.

The official free path

Gather your details: legal business name and physical address exactly as on your IRS EIN letter and state records, your EIN, bank details for payments, and your NAICS codes (census.gov/naics).
Sign in at sam.gov with a Login.gov account (multifactor authentication on).
Get Started → Register Entity. Choose "financial assistance only" for grants, or "all awards" for grants and contracts.
Receive your Unique Entity ID (UEI) during registration, then complete the remaining sections and submit.
Track your status on SAM.gov. Official emails come from @sam.gov or @gsa.gov addresses.
Renew every year. Registration lasts 365 days; renewing is free too.

Stay safe

Messages asking you to pay to register, renew, or "fix errors" are not from the government. GSA and the BBB both warn about these.
Keep your Login.gov password to yourself, always.

Free human help

Your local APEX Accelerator gives free, hands-on SAM.gov help. America’s SBDC centers offer free counseling too.

Want everything organized in one place?

The Grant Ready Kit adds a fill-in registration worksheet, a capability statement template, an NSF SBIR Project Pitch template, and a funding calendar. It follows the same free official path — registration itself stays free at SAM.gov.
