Fraud Alert Management is a fraud prevention service from Visa. This system provides continual monitoring of card activity to identify and help protect your accounts against fraudulent use. When unusual spending behaviors or transactions appear on your card, you will receive a text message asking you to confirm the transaction. These text messages will come from a short code 94209 or 23618.
If the transactions are not yours, Fraud Alert Management will assist you in blocking your cards and reporting unauthorized usage.
