Trusted Signing: Public Trust organization identity validation keeps failing for a recently incorporated EU company - what makes it pass?

I'm completing organization identity validation for a Public Trust identity in Trusted Signing (Artifact Signing), and it keeps returning Failed within about five minutes of submission. The portal shows no reason, and no email-verification link is ever received, which makes me think it fails at the organization-lookup stage, before the email step.

Context (all standard):

  • The company is a legitimately registered EU business, incorporated in 2025.
  • It has a valid national company-registration number and a live DUNS number that I've confirmed is active in the Dun & Bradstreet directory.
  • I enter the exact legal name and registered address, matching the public register.

What I've tried, each failing the same way:

  • Submitting with the registered business number as the business identifier.
  • Submitting with the DUNS number as the business identifier.
  • Re-checking the legal name, address, and primary email (on the company's own domain, which receives the Azure notifications fine).

Questions for anyone who's been through this:

  1. For a recently incorporated company, what actually made Public Trust validation pass — waiting for business records / the DUNS to propagate, using a specific identifier type, or updating the D&B record first?
  2. Is there a known manual-review path when the automated check can't verify a newer company?
  3. Anything else that commonly causes a silent five-minute failure with no reason?

(I've also opened a Microsoft support case and can share the specific validation IDs privately with a Microsoft engineer.)

Hey there, RM

I'm completing organization identity validation for a Public Trust identity in Trusted Signing (Artifact Signing), and it keeps returning Failed within about five minutes of submission. The portal shows no reason, and no email-verification link is ever received, which makes me think it fails at the organization-lookup stage, before the email step.

When an artifact signing fails, the portal never provides a reason why it has failed. Instead, people have to reach out to Azure support about this so the team can investigate why it has failed. Microsoft does have an FAQ about why the identity validation fails here: https://learn.microsoft.com/en-gb/azure/artifact-signing/faq#what-if-organization-identity-validation-fails

For a recently incorporated company, what actually made Public Trust validation pass — waiting for business records / the DUNS to propagate, using a specific identifier type, or updating the D&B record first?

When completing the Artifact signing, it says in the article that the public records for the legal business entry is up to date. This would mean the D&B record has to be up to date. If your record is not up to date, then the verification can fail. You can find more information about this here: https://learn.microsoft.com/en-gb/azure/artifact-signing/quickstart?tabs=registerrp-portal%2Caccount-portal%2Corgvalidation%2Ccertificateprofile-portal%2Cdeleteresources-portal#important-information-for-public-identity-validation

Is there a known manual-review path when the automated check can't verify a newer company?

If Microsoft is unable to verify your business, then you will get an email about about your request notifying you that Microsoft needs more information from you. Within the email, there will be a link that will direct you straight to the Azure portal where you can upload the required documents to verify your business.

You can also create a support request with Azure through the Azure support blade here: https://portal.azure.com/#blade/Microsoft_Azure_Support/HelpAndSupportBlade

You can speak to Azure support about the difficulty you are experiencing and they can go through available options with you.

Anything else that commonly causes a silent five-minute failure with no reason?I have seen a thread previously where a user had a similar problem with verification. An AI answer suggested that they didn't click onto the verification link in the verification email sent. Microsoft's own support resources say to check your junk folder in case the verification email has landed inside the junk folder. You can fin more information on this here: https://learn.microsoft.com/en-gb/azure/artifact-signing/faq#what-if-i-did-not-receive-the-email-with-the-verification-link

Microsoft does have an FAQ page around Artifact Signing here: https://learn.microsoft.com/en-gb/azure/artifact-signing/faq

Hope this informaition helps,
Nathan
