Hello Stonebranch RnD,
Thank you for reaching out to Microsoft Q&A.

When this error occurs (Error Code 715-123420 or 555420), it indicates that Azure AI Foundry has blocked GPT model deployment due to a fraud signal, and the request requires review by the appropriate internal team.

To proceed with further investigation and escalation, could you please share the details requested in private message for the same.

Thankyou!

Hi Stonebranch,

Error 715-123420 is typically an account validation/security restriction rather than a deployment or quota issue. Since GPT-4.0 and 4.1 deploy successfully but every newer model fails, I'd recommend opening an Azure Support ticket and including the Trace ID, Client Request ID, and Service Request ID from the error dialog.

In the meantime, double-check:

Your subscription is active and in good standing.

The Azure AI Foundry resource is in a region that supports the model you're deploying.

You have sufficient Azure OpenAI quota for that region.

You're using an account with the required RBAC permissions (Cognitive Services OpenAI Contributor/Owner).

I'd also recommend removing or masking your Subscription ID and resource path from this public post for security reasons. Have you already opened a Microsoft Support request? If so, what did they identify as the cause?

Please "Accept the answer" if this information helped you. This will help us and others in the community as well.

Hello and thanks for the reply, I opened the ticket here as we dont have an active support subscription. From what I read this is a know issue that needs to be resolved by microsoft internally. If that is not the case then we will have to purchase support and proceed with a ticket.
