Our 24-hour Bank by Phone service (TESS^®) lets you carry out dozens of transactions with the push of few phone buttons. All you need is your member number and a four-digit access code (not your bank card pin number), which you can obtain by contacting our call center at 918.664.6000 during business hours (8 a.m. – 6 p.m., Monday – Friday; 9 a.m. – 1 p.m., Saturday).

You can bank by phone either locally (dial 663.8377) or from out of town (dial 1.800.333.8377). Once you’ve dialed in, just follow these simple steps:

Enter your member number, plus zero, then press # (you must press # after each entry; you can cancel an entry in progress by pressing S followed by #).

• Enter your access code, then press #.
• Enter the service code (see list) for the transaction you wish to perform, then press #. (If you don’t know the service code and don’t have a list, you can press zero for a menu.)
• To access your accounts, you will need your account and/or loan numbers. You’ll find them on your statements from Oklahoma Central; you can also get them from our call center.
• To enter dollar amounts, enter the number in dollars and cents, without a period, followed by # (for example, $25.00 would be entered as 2500#).
• To perform more than one transaction, just press the code for the new transaction after the previous one is complete. You can also cancel a transaction in progress by pressing a new service code.
• When you’re finished with your transactions, press 99#.
