How to check a vendor in SAM.gov: CAGE, UEI and exclusions, before you order

Published August 27, 2026 · Last updated August 27, 2026 · 6 min read · By the Smart Gov Supply team
Short answer

Ask the vendor for its UEI (12-character Unique Entity ID) and CAGE code (5-character Commercial and Government Entity code), then run three checks, all free: (1) the entity record on SAM.gov — registration status, expiration date, purpose of registration, physical address, NAICS list and size representations; (2) the exclusions search on SAM.gov, which is the governmentwide debarment list under FAR 9.404; and (3) the CAGE record at cage.dla.mil/search, which is public and needs no login. FAR 9.405(e) requires an exclusions review after quotes are received and again immediately before award, with no dollar floor — so the check that matters most is the one you do last.

The three identifiers, and what each one is for

IdentifierFormatIssued byWhat it tells you
UEI (Unique Entity ID)12 alphanumeric charactersSAM.gov / GSAThe entity's federal identity; replaced the DUNS number in April 2022
CAGE code5 alphanumeric charactersDLA Commercial and Government Entity programConfirms the entity and its physical location; searchable publicly with no login
NAICS codes6 digits eachSelf-selected by the entity in SAMWhat the entity says it does — and where its size representation applies

Step 1 — Read the entity record

Go to sam.gov, choose Search, and filter to Entity Information. Search by UEI or CAGE rather than by name — company names are inconsistent and near-matches are common. (SAM requires a free sign-in to display full entity records; the CAGE search in step 3 does not.)

Check five fields:

  1. Registration status. Active, or expired. An expired registration is not a disqualification for a card buy under the micro-purchase threshold, but it is for a purchase order.
  2. Expiration date. SAM registrations require annual renewal. If it expires in eleven days and your award is in three weeks, raise it now.
  3. Purpose of registration. "All Awards" means the entity is registered to receive contracts. A financial-assistance-only registration is not the same thing.
  4. Physical address and business start date. Cross-check against the quote letterhead and the CAGE record.
  5. NAICS codes and size representations. Size is per NAICS code. A firm can be small for one code and other than small for another — see what a small business set-aside means for a purchase-card buyer.

Step 2 — Run the exclusions search separately

Exclusions are a different search domain on SAM.gov, and an active entity registration tells you nothing about exclusion status. Search by entity name and by UEI or CAGE — and check the principals as well as the firm where the amount at stake justifies it.

The rules behind this are stricter than most buyers realise:

Step 3 — Verify the CAGE record, no login required

The Defense Logistics Agency's CAGE program publishes a public search at cage.dla.mil/search. Enter the CAGE code or the UEI. You get the legal business name, physical address and status without signing in — which makes it the fastest sanity check when a quote arrives and you want to confirm the entity is real before spending time on it.

Step 4 — For larger acquisitions, check the responsibility record

Above the simplified acquisition threshold, a contracting officer's responsibility determination reaches further. FAR 9.104-6 requires review of the Federal Awardee Performance and Integrity Information System (FAPIIS) information in the Responsibility/Qualification records for contracts over the simplified acquisition threshold, and FAR 9.104-1 sets out the general standards a prospective contractor must meet — adequate financial resources, ability to meet the delivery schedule, satisfactory performance record, satisfactory record of integrity and business ethics, necessary organisation and facilities, and eligibility to receive an award.

What "SAM registered" does and does not mean

SAM registration is a registration, not a credential. It is not a certification, a vetting, an endorsement, an approval, or evidence of past performance. It means the entity has entered its information, made the annual representations and certifications, and validated its identity with the system. Nothing more.

Treat any vendor that presents "SAM registered" as though it were an award, a rating or a government approval with corresponding caution. What registration actually buys the buyer is administrative: FAR 4.1102(a) requires offerors and quoters to be registered at the time an offer or quotation is submitted, so a registered vendor removes a blocking step. That is the whole of it.

The corollary is equally useful: an unregistered vendor is not disqualified from a card buy. FAR 4.1102(a)(1) exempts "purchases under the micro-purchase threshold that use a Governmentwide commercial purchase card as both the purchasing and payment mechanism."

Also beware of paid "registration help"

SAM registration is free, and so is every check described on this page. GSA's Federal Service Desk (fsd.gov) provides free support. Third-party firms that charge for registration or renewal are permitted to exist, but a vendor invoice for "SAM registration renewal" from an unfamiliar company is a well-known scam pattern; nothing on SAM.gov requires payment.

A five-minute checklist

  1. Ask for UEI and CAGE in writing on the quote.
  2. Look up the entity record on SAM.gov by UEI. Confirm status Active, note the expiration date, confirm purpose of registration is All Awards.
  3. Confirm the NAICS code relevant to your requirement and the size representation for it.
  4. Run the exclusions search by name and by UEI or CAGE.
  5. Cross-check the legal name and physical address at cage.dla.mil/search.
  6. Above the simplified acquisition threshold, review FAPIIS in the Responsibility/Qualification records per FAR 9.104-6.
  7. Re-run the exclusions search immediately before award — this is the step FAR 9.405(e) actually requires and the one most often skipped.

Frequently asked questions

How do I check if a vendor is registered in SAM.gov?

Go to sam.gov, choose Search, filter to Entity Information and search by the vendor's 12-character Unique Entity ID or 5-character CAGE code rather than by name. Confirm the registration status is Active, note the expiration date, and check that the purpose of registration is All Awards rather than financial assistance only. SAM requires a free sign-in to display full entity records.

What is the difference between a UEI and a CAGE code?

The Unique Entity ID is a 12-character identifier issued through SAM.gov that became the federal entity identifier in April 2022, replacing the DUNS number. The CAGE code is a 5-character code assigned by the Defense Logistics Agency identifying an entity at a specific physical location. Most federally registered entities have both, and the CAGE record is searchable publicly at cage.dla.mil/search with no login.

Do I have to check exclusions on a small purchase?

Yes. FAR 9.405(e) requires the contracting officer to review SAM exclusion records after receipt of quotes and again immediately prior to award, and there is no dollar threshold anywhere in FAR 9.404 or 9.405. FAR 9.405(a) bars agencies from soliciting from, awarding to, or consenting to subcontracts with excluded contractors absent a compelling-reason determination by the agency head.

Does a vendor have to be registered in SAM to receive a purchase-card order?

No, if the order is at or below the micro-purchase threshold and the card is used as both the purchasing and payment mechanism — FAR 4.1102(a)(1) provides that exception. Registration is required for offers and quotations on acquisitions above the threshold. The exclusions check applies either way.

Does being SAM registered mean a vendor is approved or vetted by the government?

No. SAM registration is a registration, not a certification, endorsement, approval or performance rating. It means the entity has entered its information, validated its identity and made the annual representations and certifications. FAR 4.1102(a) makes registration a condition of submitting an offer or quotation above the micro-purchase threshold — that is its function.
