If the credit card has not been opened, you can check a basic information of your credit card, such as the status and limit of the credit card. Because you haven't opened it yet, you can call the card issuing bank, but you must have the personal information filled in when you set up the card at that time, directly transfer it to the manual, tell the ID number, and let the bank help you check the status of the card. If you don't accept it manually, remember to ask and record the call time and customer service phone number to avoid future disputes.
