If you lose your VISA debit card or it is stolen (or your account is otherwise compromised), you can report it on a special 24-hour emergency hotline, regardless of the time of day or night. In the United States, call our Fiserv Network support team at 844-508-6731. 

Be prepared to provide the following:

  • Name of your credit union
  • Your first and last name
  • Verify last 4 digits of your SS#

The representative will review recent card activity with you and inform you that you will receive follow-up directly from your credit union within two business days. Any additional necessary information will be handled by OMSEFCU. You can also email OMSEFCU and advise us of your after-hours report by using our contact form. Please be sure to provide us information on the best way to reach you to follow-up on your card concerns.
