Credit card mailing usually uses registered mail. According to the regulations of the post office, the original ID card should be provided when the registered letter is signed. If no one signs for the delivery, the courier will leave a registration form and inform the customer to pick it up at the local designated place within a limited time. If the customer fails to collect the credit card within the validity period, the card will be returned to the credit card center. Please pay attention to the relevant information reminder.
