Can’t verify my account number

My number set up on 2017 has changed a while ago but it still links to my Apple ID. And I’m asked to change it to the new one, which I did. But my new number appears to be an “invalid number”, I don’t understand why. I’ve been using this number for a year I know it’s a valid number, is it because of something else?
