Debit or Credit Card Lost/Stolen

If your card is lost or stolen, please call the applicable number below IMMEDIATELY.

For lost/stolen debit cards: (800) 523-4175

For lost/stolen credit cards: (727) 570-4881

Then call OTCU at (920) 233-2611 during regular business hours to order a replacement card. Do NOT wait until the next day or after the weekend to contact OTCU. Lost or stolen cards need to be reported just as soon as you are aware that the card is missing.

By reporting it immediately, a block will be placed on your card, stopping further transactions. If you report your missing card after business hours, we will contact you during office hours to go over recent transactions directly with you. OTCU will order a new card for you, and we can assist you with filing a transaction dispute, if necessary.
