Your loan number can be found on your monthly Visa statement. It is also displayed in Online and Mobile Banking. Authorized user's card will be mailed to the primary cardholder's address on file.

If you permit another person to use your account, you agree to pay for (1) any transactions made by that person and (2) charges imposed on those transactions, even if the amount of the actual use exceeds your permission to the extent allowed by applicable law.
