Lost or stolen Visa® card?

If your VISA Credit Card, VISA Debit Card or ATM/Cash Card is lost or stolen, the easiest and quickest way to block it is via our Mobile Banking app 1 installed on your iPhone or Android device. Cards can be frozen temporarily (if the card is simply misplaced) or blocked permanently with a new card ordered.

If you do not want to use the Mobile Banking app1, please call us during normal business hours at (425) 643-3400 or toll-free at 1-800-848-0018.

After business hours, please call 1-800-228-9901 and the system will provide you with instructions.
