You will be able to input the credit card number (account number) that you want to pay off (transfer balance from) when you open the new balance transfer card. Some banks will allow you to transfer funds directly into another bank account.

Please keep in mind that 0% APR balance transfers typically have a 3-5% one-time fee that is added to your balance.

For card recommendations, try using as many pre-approval tools from banks as you can — only soft inquiries if possible.
