Of course. According to public information, when applying for a credit card, the bank will ask you to provide your mobile phone number. This mobile phone number is used to receive verification codes and notifications, so it must be used normally. If you don't have your own mobile phone number, or don't want to use your own, you can use someone else's mobile phone number, such as your relatives, friends or colleagues. But you have to make sure that this mobile phone number is used frequently by you and has been recognized by the owner of the mobile phone number. Otherwise, you may miss important information or cause trouble to others.
