Error 715-123420 — fraud-detection block on all GPT-5 model deployments.

Hello Sorin Buzatu,

Greetings! Thanks for raising this question in Q&A forum.

I completely understand how frustrating this is, especially since you have already done a thorough job ruling out every configuration-level cause. You are absolutely right in your diagnosis.

Error 715-123420 is not a quota issue, not a region availability issue, and not a resource configuration problem. This specific error code means your deployment request was intercepted and blocked at the platform level by Azure's Real-Time Fraud Protection (RTFP) system. This is why the failure is immediate, consistent across GPT-5 family models, and persists regardless of region or SKU, while your gpt-4o and other smaller models continue to work fine.

You cannot resolve this by changing regions, adjusting quotas, or altering RBAC permissions. This block requires a manual review by Microsoft's internal Fraud Protection and Security team.

Here is what you should do:

1. Stop retrying or recreating resources Do not keep retrying or deleting and recreating resources, as it usually does not clear this kind of block and can make the activity pattern look worse.

2. Open an Azure Support ticket with the right routing Go to the Azure Portal and open a support ticket. Phrase it as a "715-123420 deployment validation block" and explicitly request that it be routed to the RTFP / Fraud Protection / Security backend review team. Include your correlation IDs, subscription ID, working deployment proof (your gpt-4o deployments), failing model and SKU or region combinations, and UTC timestamps of the failed attempts.

3. Use these details in your ticket Make sure to include:

• Subscription ID: a74ce9d7-8c96-4b79-9b6a-e696e6569f47
• Resource: aIdocumentprocessor-openai, resource group TestEnvironment, region Poland Central
• Model attempted: gpt-5.4 (version 2026-03-05), GlobalStandard, 150K TPM
• Proof of working deployments: gpt-4o, gpt-4o-mini, text-embedding-3-large on the same resource
• CLI command used and the exact error response received

4. If the portal blocks technical ticket creation If the portal blocks support ticket creation, post the same details in Microsoft Q&A without any secrets and ask a moderator to route it privately. A Microsoft FTE moderator can generate a secure collaboration ticket on your behalf.

5. Reference your Developer Support Plan When creating the ticket, mention that you hold a Developer Support Plan subscription. This should entitle you to technical ticket routing. If the portal is still not cooperating with ticket creation, escalate through the Q&A forum thread directly by requesting moderator assistance.

To help expedite resolution here in the Q&A forum, please reply with your Azure OpenAI Account Resource ID (do not share any private keys or secrets) so that a Microsoft FTE moderator can open a secure collaboration ticket to engage the RTFP review team on your behalf.

If this answer helps you kindly accept the answer which will help others who have similar questions.

Cause:

Error 715-123420 is a fraud-detection block from Azure. It triggers when your subscription fails risk checks for high-demand models like GPT-5/GPT-5.4. Common reasons: new subscription, low spend history, missing quota request, or flagged payment method.

Fix Steps:

1. Check Access: GPT-5/GPT-5.4 requires approved access. Go to Azure AI Foundry > Deployments > Request access. Submit the form for GPT-5 if you haven't already.
2. Quota Request: Even with access, you need quota. In Azure Portal > Azure AI Services > Quota, create a quota request for GPT-5 in your region. The fraud block appears if quota = 0.
3. Bypass Support Ticket: Since normal tickets fail, use this path: Azure Portal > Help + Support > Create a support request > Service and subscription limits (quotas) > Azure AI Services. Select "Fraud/Block Error 715-123420" in description. This queue is handled by the AI team, not general support.

Note: Until Microsoft whitelists your subscription, no workaround will work. This block cannot be removed from your side.

Hope this helps you get it unblocked.

Hello @Sorin Buzatu

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!

Thank you so much, Muhammad Saad Rashid!

1. I did not find the "Request access" option, but I have access just for the record and I have GPT-4o deployed (since I have created the Openai project).
2. I could manage to request a quota increase, I will be back with the answer once I receive it.
3. Still I could not really create a support ticket, always it lands on the suggestions, with no options to really create a support ticket.
