Hi @اسماء محمد ,
Thanks for reaching out! I understand you’re trying to set up a Microsoft Developer account, but the system isn’t accepting your phone number. This usually happens due to regional restrictions or unsupported phone carriers during identity verification.
These are possible causes:
- Region not supported for SMS/voice verification: Some countries or regions don’t support MFA via phone.
- Carrier limitations : Certain carriers block short codes or international verification messages.
- Number format issues: The phone number must include the correct country code and no extra characters.
These are the recommended steps:
- Verify regional support: Check if your country is listed as supported for MFA in the Microsoft Entra MFA availability guide.
- Try an alternative method: If SMS/voice isn’t available, use the Microsoft Authenticator app for verification. Here’s the setup guide: Set up the Microsoft Authenticator app.
- Ensure correct format: Use the full international format (e.g.,
+1 555 123 4567). - Check carrier restrictions: Contact your mobile provider to confirm they allow short code messages.
