Frequently Asked Questions

Why am I not receiving the verification code from Azure?

This can happen due to network carrier blocks, incorrect country code formatting, VoIP number restrictions, or temporary backend issues with Microsoft's SMS gateway.

Can I skip phone verification during Azure sign-up?

No, Microsoft Azure requires mandatory phone verification for all new accounts to prevent fraud, spam, and automated bot registrations.

Is there a limit to how many times I can request an Azure verification code?

Yes, requesting a code too many times in a short period may result in a temporary block on your phone number. It is recommended to wait at least 24 hours before trying again if you hit this limit.

Can I use a virtual phone number for Azure verification?

Microsoft typically blocks VoIP and virtual phone numbers (such as Google Voice) during the Azure sign-up process. You must use a standard mobile or landline number.
