To check the available limit of Industrial Bank’s credit card, you can edit the text message "Query Limit" and send it to 400-889-5561. After a while, you will receive the available limit text message from the bank. Inquiries can also be made through online banking and calling customer service phone numbers. Increasing the credit card limit can provide sufficient financial proof information when applying for a credit card, such as your income certificate, bank deposit certificate, real estate certificate, car ownership certificate, etc.
