Help guard your card from fraud with our Guardian Text Alerts. Once your Debit Cards and Credit Cards are enrolled you will get text alerts notifying you when your cards have been used for the following transactions:

  • International transactions
  • Fuel transactions
  • Authorizations greater than $200
  • 6 or more transactions in 24 hours
  • Card not present transactions
  • Out of state transactions
  • Declined authorizations

If the transaction listed in the text alert is accurate, there is no need to do anything.

If there is suspicious activity on your card, simply reply to the text with the code included in the text alert and your card will be blocked from further use.

The text alerts from Guardian Alerts will never ask for your card number or your personal information in the text message.

We offer this service for free to our members. Message and data rates may apply. You may discontinue this text alert service at any time by texting STOP to 27576.
