Due to a system upgrade, all OMB customers have been issued and should have received a
replacement debit card along with a detailed letter explaining the upcoming transition. Your
existing card will expire at 11:59 p.m. on Sunday, November 12th. Please remember to activate
and begin using your new card after midnight on Monday, November 13, 2017. ATM machines
located at our five banking center locations may also experience temporary service interruptions
on November 13th and we do apologize in advance for any inconvenience.
If you have not received your replacement debit card or have questions please contact us at (417) 869-9000.
