There are two situations when applying for a credit card without a card number: 1. Overdue or failure to pay the annual fee (each bank has regulations). 2. Not using your credit card for a long time will lead to consumption failure. The platinum card has not been opened, the account has been frozen, etc. 3. If you don’t use the card for a long time, you still don’t enjoy the revolving credit facility. 4. If the customer refunds and there is no funding channel, the transaction will be authorized to be offset and the account will be automatically closed.
