UEI (Unique Entity Identifier)

In short

The UEI is a twelve-character identifier for an organisation in the US federal grants system, issued free of charge through SAM.gov. Without an active registration an application never reaches substantive review, and the longest stage here is not the registration itself but the validation of the organisation.

The Unique Entity Identifier is the American counterpart of the European PIC: a single organisational identifier across all federal grant procedures. It is issued by the US government through SAM.gov and belongs to the government.

DUNS is gone

Until 4 April 2022 this role was played by the DUNS number issued by a private company. It has been fully replaced. A document still requiring a DUNS number is at least four years out of date.

Time and cost

Obtaining the identifier and registering in SAM.gov are free. Worth repeating, because a market of intermediaries charges for what the government does at no cost.

Official estimates vary: the system itself quotes up to ten business days, while State Department call documentation for 2026 says four to eight weeks. All of these clocks start after entity validation, which is a separate step.

Registration must stay active

Both while an application is under consideration and throughout the period of performance of an award. It is renewed annually.

The consequence of lapsing is blunt: an application with an inactive registration does not reach substantive review at all. It is not scored lower – it is not scored.

You probably do NOT need an NCAGE

This is the most common outdated advice and it costs people weeks. Foreign entities once had to obtain an NCAGE code before registering. It is now needed only in two cases: if you register for "all awards" (contracts and grants) or if you seek Department of Defense funding.

An organisation applying for an ordinary grant selects "financial assistance awards only" – and needs no NCAGE at all. Many guides, including on government sites, still say otherwise, because SAM.gov is a government-wide system covering other cases.

What actually slows registration down

Not the NCAGE but entity validation – a separate step that precedes registration and adds to its duration.

The leading cause of rejection is documents not matching what you entered in SAM.gov, character for character. Next is translation: it must be certified in the prescribed form and done by a person – machine translation is not accepted. Then stale documents: a registry extract must be no more than a year old.

A separate trap: a PO box or virtual address is not accepted as a physical address, nor are coworking spaces, storage units or registered agent addresses.

And a technical detail that costs days: if the validation service asks for documents and you do not reply, the ticket auto-closes after five days – and the agent will not see anything you upload later.

Two exemptions worth knowing

Subrecipients do not need full registration – the identifier alone suffices. If you receive funds as a partner of a US organisation rather than directly, obtaining a UEI is enough.

An agency may also exempt a foreign organisation from full registration for an award under $500,000 performed outside the US – though the UEI is still required. This is the agency's discretion, not your entitlement: State Department documentation requires requesting such an exemption at least two weeks before the deadline, with the grants officer's approval.
