At Bank of Oklahoma we believe in financial peace of mind. Overdraft Protection provides convenient automatic transfers from your linked Bank of Oklahoma savings or money market account to your checking account to cover transactions, should your checking account balance drop too low.


There's no cost to enroll in Overdraft Protection. You only pay a transfer fee* when you use the service. If you have (or plan to open) more than one account at Bank of Oklahoma, then Overdraft Protection may be right for you.


You can enroll in Overdraft Protection by calling ExpressBank at (800) 234-6181, by visiting one our local banking centers or by requesting it through the Online Banking Secure Message Center.

Helpful tip:
We also offer free account alerts that can be easily set up in Online Banking to help safeguard your accounts from overdrawing. Set alerts to monitor your account activity, including your balance. You can even have alerts sent to multiple email addresses.

*A nominal transfer fee may apply. See summary of fees for pricing.
