Credit card balance inquiry methods are:

1. You can make inquiries at local bank outlets with your valid personal ID and credit card.

2. Call the credit card customer service hotline of the issuing bank, and then follow the voice prompts to check the balance, or directly transfer to the manual service and ask the customer service to help you check;

3. Log in to the online banking and mobile banking of the issuing bank, and find the relevant information of the credit card for inquiry.

If you don't have time to go to the local outlets, it's faster and easier to check the balance by phone.
