Entity validation is the stage of SAM.gov registration where most applications stop. It is also the least well explained, which is why businesses can sit in it for weeks without understanding what is being asked of them.
If you have seen a message telling you your entity could not be validated, or your registration has been sitting unresolved with no clear reason, this is the page you want.
What entity validation is
Before issuing a Unique Entity ID, SAM.gov confirms that your business is real and that you are who you say you are. It does this by matching the legal business name and physical address you enter against authoritative records — your state formation documents and other official sources.
The match has to be exact. Not close. Exact.
Why validation fails
- Punctuation and abbreviation. “Smith & Sons, LLC” and “Smith and Sons LLC” are different strings. So are “L.L.C.” and “LLC”, and “Street” and “St.”
- Trading name versus legal name. The name on your signage, invoices and website is often not the name on your formation record. Validation uses the legal one.
- PO boxes. SAM.gov requires a physical address. A mailbox will not validate.
- A recent move that has not yet been reflected in your state records.
- Suite and unit formatting entered differently from the official record.
- Documentation problems — a document that is too old, the wrong type, illegible, or does not show both the name and the address together.
None of these mean your business has a problem. They mean two databases disagree about a comma.
What we do
We start by finding out what the authoritative record actually says, rather than guessing. Then we identify precisely where your submission diverges from it, and decide which side needs to change — sometimes the SAM.gov entry, sometimes the underlying state record.
We assemble documentation that satisfies the requirement, submit the validation, and follow it through the incident process if it needs escalating. You end up with a Unique Entity ID and a registration that can proceed.
About the UEI
The Unique Entity ID is a twelve-character identifier issued by SAM.gov. It replaced the DUNS number in April 2022. You do not apply for it separately and you do not pay for it — it is assigned once validation clears.
If a prime contractor or grant officer has asked for your UEI and you do not have one, validation is the step standing between you and it.
Common questions
Can I get a UEI without registering fully in SAM.gov?
Yes. SAM.gov allows you to obtain a UEI for identification purposes only — useful if a grant application or prime contractor needs one but you are not yet bidding. You still have to clear entity validation to get it.
What documents will I need?
Typically something official showing your legal business name and physical address together, and current. Which document works depends on your entity type and state. We tell you exactly what to send before you spend time gathering the wrong things.
My validation has been stuck for weeks. Is it lost?
No. Stuck validations are usually one specific mismatch away from clearing. The difficulty is that the system rarely tells you which one.
Do I need a new UEI if I move or rename the business?
No, but you do need to update your registration, and that update will re-trigger validation against the new details.
Where we work
We deliver nationwide, remotely. Federal registrations, federal and foundation grants, and proposal work are not tied to geography — most of our engagements never require anyone to be in the same room.
In California we work across Los Angeles County, Orange County, Riverside County, San Bernardino County and the wider Inland Empire, plus San Diego, Ventura and the Central Valley. State-specific programmes such as Cal eProcure and California SB certification are, by definition, California only — everything else travels.
Our office is in downtown San Bernardino. See all service areas.
