Lost or Stolen Card

If your debit or credit card has been lost, contact your branch immediately! The local numbers for the individual branches can be found on our Locations page.


You can also contact us at 800-775-1889 or at 406-449-2265. Your debit card will be closed by a New Accounts Rep to prevent any unauthorized transactions. In addition, we will call and request that a new card be ordered for you.


If you need assistance after banking hours, please contact Fraud Services at 1-800-528-2273.**


**Mountain West Bank switched debit card providers in October of 2012, and your current debit card may have the previous contact number listed, 866.842.5208. This number is no longer valid and cannot be used to report your card as lost or stolen. Please refer to the Fraud Services number listed above, or contact the bank directly during regular office hours.
