Solution 1Recommended

Verify Phone Number Type and Account Details

Since Microsoft does not have a general regional restriction for Uzbekistan, verifying the exact phone type and account state can help identify the root cause.

Certain verification methods behave differently depending on whether you are using a mobile device or a landline. Properly identifying the account setup phase is also crucial.

Identify the Phone Type

Determine whether the Uzbek number being used is a mobile phone or a landline. If you are using a landline, ensure you select the voice call verification option, as SMS verification will fail.

Check the Account State

Confirm whether you are signing up for a brand-new Microsoft Entra account or updating the security information for an existing one, as the portal configurations may vary.

Document the Error Safely

Take a screenshot of the exact failure message on the Microsoft Entra screen. Before sending this to your IT administrator or Microsoft Support, redact the full phone number and any sensitive personal data.

Support Information: Providing a redacted screenshot alongside the device type (mobile/landline) significantly speeds up the troubleshooting process with IT support.

Solution 2

Use Microsoft Authenticator App as an Alternative

If SMS or voice verification continues to fail, using the Microsoft Authenticator app provides a reliable alternative for completing identity verification.

Frequently Asked Questions

Are there regional restrictions for Microsoft Entra phone verification in Uzbekistan?

Official Microsoft documentation does not indicate any general regional restrictions for phone verification in Uzbekistan. Failures are typically tied to carrier issues, phone type (landline vs. mobile), or incorrect formatting.

Can I use a landline for Microsoft Entra MFA verification?

Yes, landline numbers are supported by Microsoft Entra, but you must select the 'Call me' option during setup. SMS text messages cannot be delivered to standard landlines and will cause the verification to fail.

What should I do if my SMS verification code never arrives?

If you are not receiving SMS codes, try selecting the voice call option, check with your telecom carrier to ensure shortcodes are not blocked, or bypass the phone number entirely by setting up the Microsoft Authenticator app.
