Credit card return visit is the most direct way to verify whether the applicant applies for a credit card himself.
It doesn't matter if you don't get a call the first time. When you see an incoming call, you can call back during the business hours of the card department. If there is no answer to many calls, the card department will refuse the credit card application on the grounds that "there is no answer to many calls".
It is suggested that when applying for a credit card, regardless of the applicant's mobile phone or fixed phone, he should leave his commonly used mobile phone number or someone should answer the fixed phone to avoid affecting the verification and approval of the credit card.
