Why did I get a Fraud Alert for pumping gas?
A pre-authorization at the gas pump will trigger a Fraud Alert. ACCEPT this alert if you are indeed pumping gas so that your debit card does not get restricted from use for potential fraud.
Most gas pumps will only do a $1 pre-authorization so the merchant knows there are funds to cover the purchase of gas/fuel. Some common gas pumps that do LARGE pre-auths are Murphy’s/Wal-Mart, H-E-B, Shell, and SAM’s Club. These pre-authorizations can range from $75-$100. The pre-authorization normally falls off after your gas transaction settles.
