    Travelling? Let Us Know

    Are you planning on travelling soon?  Whether it's for a three day ski trip to the mountains, or a month-long vacation to the south, let us know before you go.  Advising us of your travel plans before leaving will ensure that you have uninterrupted access to your money while you are away. 

    Letting us know when and where you will be travelling aids in extra security for you and your money.  All accounts are monitored for suspicious or unusual card activity.  Without notifying us of your travels, transactions for high amounts, out of the country, or more frequently than usual can result in your card being blocked for security purposes, until we can contact you.  Contacting your branch of Diamond North Credit Union and Mastercard will avoid any disruptions to your card use while you are away from your normal business area. 

    When you call, please let us know what country and/or US states you will be travelling to, when you leave and when you will return.  We'll take care of everything else. 

    If you have a MemberCard Debit Card please call your branch of Diamond North Credit Union. 

    If you have a Collabria Mastercard Credit Card, please call 1-855-341-4643 (the number on the back of your card). You also have the option to report your travel plans by logging into MyCardInfo, selecting Account Services, then Travel Center.
