Issue with creating Free Store Developer Account

Question

I've been trying to create an account for an hour, on two laptops and mobile device but I keep getting the error: 'Account creation failed. OnenessService call failed: Request failed with status code 400.' Has anyone dealt with this issue before? How did you fix it?

Answer 1

If you're encountering the error "Account creation failed. OnenessService call failed: Request failed with status code 400," it may be related to issues with the information you're providing during the account creation process. Here are a few troubleshooting steps you can try:

1. Check Your Information: Ensure that all the details you are entering are accurate and match the required formats. This includes your email address, publisher display name, and any other personal information.
2. Identity Verification: Make sure that you are completing the identity verification step correctly, which involves providing a government-issued ID and a selfie. Ensure that the images are clear and taken in good lighting.
3. Browser Issues: Try clearing your browser's cache and cookies or using a different browser altogether. Sometimes, browser settings can interfere with the account creation process.
4. Network Issues: Ensure that your internet connection is stable. A weak connection might cause issues during the account creation process.
5. Contact Support: If the problem persists, you can reach out to Microsoft Support for assistance. For issues related to the new onboarding process, you can email ******@service.microsoft.com.

Following these steps may help resolve the issue you're facing with account creation.

Answer 2

I'm having the same problem. I've been trying to create my account since yesterday (December 6, 2025), I've tried on 2 computers, my cell phone, my tablet, using Chrome, Edge, and in incognito tabs, and I still get the same error: "Account creation failed. The call to OnenessService failed: The request failed with status code 400." I identified in the Devtools console logs that the error may be related to the geocode, since it returns error 500.

Note that in the logs below there is a 500 error in the POST request to /api/location/geocode/simple. This error occurs in the console just before the error "Account creation failed. OnenessService call failed: Request failed with status code 400".
