Hi DRay210,

Welcome to the Apple Community

Re: i changed my phone number cant do verification

If you have another trusted device listed in your Apple ID account,:

you can likely get a verification code from that device to complete sign in

.. once signed in, you would be able to add the new phone number before deleting the old phone number.

If needed:

A trusted device is an iPhone, iPad or iPod touch with iOS 9 or later, 

or Mac with OS X El Capitan or later that you've already signed in to using two-factor authentication.

 It’s a device we know is yours and that can be used to verify your identity by displaying a verification code from Apple when you sign in on a different device or browser.

NB: You may need to add the new phone number before you can delete the old phone number.

If you do not have a trusted device to help you access your account, and change your phone number.
