Applicants for CCB supplementary cards must be over 13 years old.

Applicants for supplementary cards are natural persons who have no capacity for civil conduct or are restricted from civil conduct, and need to obtain the consent of their guardians. Moreover, the main card of a private bank card can only have one supplementary card. Currently, the supplementary card application can only be processed through the local branch of China Construction Bank. During the application process of the supplementary card, the main and additional cardholders must go to the branch at the same time to apply.

How to apply for a credit card supplementary card:

1. Credit card supplementary cards can be applied for at bank branches. In addition to branches, cardholders can also apply through the bank's official website, mobile banking and telephone. . Please note that the monthly bill of the supplementary card is calculated in the main card bill, and the main card bill is also paid by the main cardholder;

2. Compared with the main card, the supplementary card can be paid by the main cardholder. Apply for a supplementary card for a natural person who is over 13 years old and has full capacity for civil conduct, or a natural person who has limited capacity for civil conduct. If the applicant for the supplementary card is under the age of 18, he must obtain the consent of his legal representative;

3. The amount in the supplementary card comes from the main card, and the bills of the supplementary card are repaid by the main cardholder. This means that the two cards share a limit, and the main cardholder can set the consumption permissions of the supplementary card and make repayments at the same time.

To sum up, the supplementary card can only be applied for together with the main card. The main cardholder must be present at the time of application. The rights and obligations of the supplementary card and the main card are basically the same. The supplementary card can enjoy the same benefits as the main card. The card has the same annual fee preferential policy, and the application for reporting the loss of the main card will not affect the use of the supplementary card. The supplementary card will be sent to the main cardholder's address after issuance to ensure that the main cardholder's address is valid before the card is issued.
