@Nagaraj - Welcome to Microsoft Q&A and thanks for reaching out to us.
If you’ve never signed up before, you should be able to create an Azure free account regardless of the phone number used. Azure has a robust system that prevents multiple free accounts for the same user. Specifically, the Azure free account is available to new Azure customers who haven’t previously had an Azure free account and received a $200 credit.
When it comes to account recovery, Microsoft typically uses phone numbers for security verification. However, the process varies depending on the specific service (e.g., Azure, Microsoft 365).
Each Microsoft 365 account requires a unique phone number for security purposes. Attempting to use the same phone number across multiple accounts may lead to issues with verification and account access.
Remember that while using the same phone number might seem convenient, it’s essential to follow guidelines and avoid misuse. If you encounter any issues, consider reaching out to Microsoft support for personalized assistance.
Hope this helps. and please feel free to reach out if you have any further questions.
