Managing personal Outlook.com account settings, security, and privacy
Hello,
I am Ibhadighi and I would happily help you with your question. In this forum, we are Microsoft consumers just like yourself.
Apologies for the inconvenience. Microsoft's policies for phone number support in account registration and security verification may vary by country or region. Some countries may have limited or restricted support for adding phone numbers to Microsoft accounts due to regional regulations, telecommunications agreements, or other factors.
If you're experiencing difficulty adding your phone number to your Microsoft account in Nepal and receiving a message that the country code is not supported, you can also try Alternative Verification Methods. Microsoft typically offers alternative verification methods, such as using an email address or security questions, to help secure your account.
Best Regards, IBHADIGHI
