Start monitoring your Union Bank debit and ATM card usage today with smsGuardian alerts. smsGuardian gives debit and ATM card users the option to receive and respond to text alerts for card transactions that post to their Union Bank account1. Once enrolled, you will start receiving text message notifications to your cell phone or other sms text messaging devices when your Union Bank card transaction falls into one of the below categories:

Debit/ATM Card Transactions That Trigger Alerts

  • Transactions over $50
  • International transactions
  • More than 5 transactions in a 24-hour period
  • Card not present (internet) transactions
  • Out of State transactions
  • Declined authorizations

What to Do If You Receive an Alert for a Transaction You Didn't Authorize

If you receive a text alert for a transaction that you did not authorize, simply reply to the text message with the unique code that was included in the original notification. By replying to the text message, the fraud process will be started. Your Union Bank card will be warm carded with all future purchases being stopped. A Union Bank customer service representative will contact you to order a new debit card and process any necessary paperwork for the fraudulent transaction.
