Hello Vikas,
If the ID you're planning to use for verification does not include your last name, you could try entering your first name in both the first name and last name fields or initial in your last name field when creating your Azure free account.
However, this may cause issues with verification. Best option here is to contact Microsoft support and explain your situation. They may be able to provide alternative options for verifying your identity, such as providing additional documentation or using a different form of identification.
To contact Microsoft support, you can visit the Azure support center and select the "Contact us" option. From there, you can choose to chat with a support agent, submit a support request, or request a callback.
It's important to provide accurate information when creating an account to ensure the security of your account and prevent any potential fraudulent activity.
Hope this helps!
Regards,
Divya.
