How to Fix Microsoft AppSource Sign-Up and Phone Verification Failed
Question details
Users are unable to complete the phone number verification process when signing up for Microsoft AppSource with a work or school account.
- Product
- Microsoft AppSource
- Device & OS
- not provided
- Scenario
- Signing up for Microsoft AppSource to download or manage applications using a work or school account.
- Observed behavior
- Phone verification fails, preventing the user from completing the sign-up process and accessing the platform.
Ensure you are using a valid work or school email address, as personal Microsoft accounts are generally not supported for AppSource developer or enterprise sign-ups.
Verify Phone Number Format and Regional Support
Correcting formatting issues and ensuring your region is supported is the most common fix for verification failures.
Microsoft's automated SMS verification system is sensitive to formatting errors. If the phone number is entered incorrectly or carrier restrictions apply, the verification code will not be delivered.
Ensure the country code selected from the dropdown exactly matches the physical location of your registered phone number.
Type your phone number without any leading zeros, spaces, dashes, or special characters.
Ensure your mobile carrier does not block automated SMS texts or shortcodes from Microsoft. You may need to contact your carrier to unblock premium SMS services.
Contact Organization Administrator or Microsoft Support
If the number format is correct but verification still fails, your organization's Azure AD settings might be blocking the action.

Frequently Asked Questions
Why does AppSource say my email address is not supported?
Microsoft AppSource typically requires a corporate or educational email address tied to an Azure Active Directory (Microsoft Entra ID). Personal email addresses like @outlook.com or @gmail.com are not supported.
How long does a temporary phone verification block last?
If you trigger a temporary block due to too many failed SMS requests, the block typically clears after 24 hours. Wait a full day before attempting to verify the number again.
Can I use a virtual phone number (VoIP) for Microsoft AppSource verification?
Microsoft often rejects VoIP numbers, virtual numbers, or landlines for SMS verification. It is highly recommended to use a standard mobile phone number from a supported cellular carrier.
