Internal & External Transfers
In KCNB Online Banking, you can easily transfer money either between the eligible accounts you own at KCNB, or accounts you own at another financial institution!
The External Transfer feature will allow you to add a DDA account you own at another financial institution.

The verification process may take a couple of days.
Once your account is verified, you will be able to send money to that account, and also request money from that account within KCNB Online Banking & KCNB Mobile.
The External Transfer feature has a standard delivery fee of 0.50¢ per transfer. Next-day transfer option may also be available at a fee of $5.00 per transfer. $10.00 minimum transfer.
