The phone number is something important that many companies need in order to confirm orders via phone and not just by email. As I was doing a demo on the checkout page, I inserted an alphabetical letter H instead of a digital number, and it seemed that after I hit next, the system accepted it normally without any errors. That is not good at all. Phone numbers must be have limited characters when a user provides his/her number. For instance, if a user lives in the US, and he/she selects United States as their country on the form, the phone field will automatically switch to have a prefix of +1 where the user can only then insert his/her mobile's 7 digit number in order to continue the checkout process. This is important to be validated because often many times users misspell their phone number accidentaly without rechecking what they had typed. So please fix this as it is quite embarassing at the moment. Thx!
