Now you can use your Canadian MasterCard® card to pay at the pump when you fill up in the U.S.
Most U.S. gas stations require a ZIP code when paying at the pump with a credit card. MasterCard can help.
Take the three numbers in your postal code.
Add two zeros to the end.
Use this number if they ask you for your U.S. ZIP code.
If prompted for your ZIP code, just enter the three digits of your postal code plus two zeros. So for example, if your postal code is A2B 3C4, the 5 digit number you should enter is 23400. Contact your card issuer if you have any questions.
