I applied for a credit card in ICBC. Why can't I apply for a supplementary card online? When applying, you will be prompted "The card you selected does not support applying for supplementary cards".
Hello, this prompt indicates that your credit card type does not support applying for a supplementary card, and you can only use one main card for spending. If you confirm that you want to apply for a sub-card now, you can apply for consultation at the outlets to see if you can handle the counter. If it still doesn't work, I suggest you choose a card type that can handle the secondary card, open one, or directly help people who need to handle the secondary card to handle the credit card, but it is directly related to you.
