What is a UEI and how do I get one?
As of 12 November 2026: The Unique Entity ID (UEI) is a 12-character alphanumeric identifier that SAM.gov assigns to an entity when it passes validation. You get one in SAM.gov, either as part of a full registration or by requesting a UEI only; a UEI only does not let you bid directly on federal contracts as a prime contractor.

- In your Workspace, select 'Get Started' in the Entities section.
- Choose to register your entity (needed to bid) or to get a Unique Entity ID only.
- Enter your legal business name and physical address so SAM.gov can validate your entity; submit documents if it cannot find you.

Questions people also ask
- Do I need SAM.gov registration to bid on federal contracts?
- Yes, in most cases. FAR 4.1102(a) requires offerors and quoters to be registered in SAM when they submit an offer or quotation, and the provision at FAR 52.204-7 requires registration when submitting an offer and at time of award. There are listed exceptions, such as micro-purchases paid with a Governmentwide commercial purchase card.
- How long does SAM.gov registration take to become active?
- SAM.gov guidance says to allow at least ten business days after you submit your registration for it to become active. If the registration fails TIN or CAGE code validation, SAM.gov emails instructions and you must fix the information and resubmit.
- How do I know if my SAM.gov registration is active?
- Sign in to SAM.gov and use the entity status check: enter your Unique Entity ID or CAGE code and the registration status displays. Under FAR 52.204-7, an entity counts as registered only after the Government has validated the data and marked the record "Active".
