Phone verification is not picking up that I've added my phone number to it even though it's...

• Go to Manage your security info and sign in with your Microsoft account.
  
• Select Add New under Phone number or under Alternate email address.
  
• Follow the instructions to set up and confirm the new proof.
• If you already have a proof on your account, you might need to use that proof to verify the addition of a new proof.
  Note Proofs can be added to new accounts without validation for a short period. Existing accounts will need to have their proofs validated by using an existing proof.
  
• If you’re unable to access any of your current proofs (such as a phone number you don’t recognize or an expired email account), see Get help with
  your Microsoft account security proofs.

The proof is fully set up,I'm sure of it.I was trying to check my billing information,something I know requires verification,just to check to see if my mobile phone is working as a proof.It says it has sent a code to my phone,but
I've tried this before,waiting hours,still no code.I really want my phone as a security proof because the only other good proof I have is my Trusted PC,but if my computer breaks or I get a new one,I'm going to need my phone as verification to set up a new
Trusted PC.

The odd thing is though,my number listed on my security info starts with 4,yet I entered it as starting with 04,as all mobile numbers in Australia start with 04.For some reason though it has dropped the 0 from the start of my number.All
mobile numbers here start with 04,unless you call it using the country code,then the 0 gets dropped and it's just +614.Is it possible that the verification code gets sent from somewhere in Australia,and because it's dropping the 0 from the start of my number
and not using the country code,it's not working?I have tried removing my phone as a proof and adding it again,but every time it removes the 0,so I don't know what I can do about it.

Hello VJayJJ, My name is David. I am an independent advisor, happy to help you today.

I understand you're having trouble adding your phone number to your Microsoft account. Here are some suggestions that might help you:

Try adding a different number: Go to your Microsoft account page and click “Add a phone number.” Now enter a different phone number that you are using and save the changes.

Request another verification code: Try adding the number again after a few hours or even a day. You will receive a request code.

Use a '0' prefix with your phone number: For example, if your phone number is 493-XXXX, try entering it as 0493-XXXX2.

Clear your browser's cache and cookies: This can often be a crucial step in resolving validation issues.

Try adding a different number: Go to your Microsoft account page and click “Add a phone number.” Now enter a different phone number that you are using and save the changes.

Request another verification code: Try adding the number again after a few hours or even a day. You will receive a request code.

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best regards.
