There is no uniform upper limit on the number of supplementary cards for credit cards, and different banks and different credit card products may have different regulations. Generally speaking, most banks will allow primary cardholders to apply for multiple secondary cards, and the specific number is usually between 2 and 5.

However, it should be noted that each supplementary card will share the credit line with the main card, and the cardholder of the main card is responsible for the consumption and repayment of all supplementary cards. Therefore, the bank may carefully decide the number of supplementary cards according to the credit status and repayment ability of the main cardholder.

Whose name is the credit card sub-card?

You can choose to apply in the name of the primary cardholder or the secondary cardholder. Each supplementary card will be printed with the cardholder's name so that the cardholder can easily identify it.

The secondary card and the primary card have different numbers, but they belong to the same account and share the credit line. For example, if the credit line of the main card is 10000 yuan, the available credit line of the main card will be reduced to 8000 yuan after the secondary card uses 2000 yuan. When the vice cardholder uses the credit card, the consumption generated by the main cardholder shall be borne.
