Invalid phone number in Apple ID account manager
Hello,
I can't save Payment & Shipping settings, because of invalid phone number error:
Area code is entered correctly and it doesn't show error.
Where is the problem?
If you are sure you have entered the correct number, contact iTunes Support. Either use the form or scroll to the bottom of the page in the 2nd link. Follow through the screens to get a chat or telephone option. You may need to pick a problem that is slightly different than yours to get a chat option.
