This past December when my family were in Orlando, a lot of places my Dad went to get gas would not let him pay at the pump with his credit card, because we didn't have a zip code to put in at the pump. The reason for us not having a zip code, is because my family & I are from Canada where we have postal codes (numbers & letters). However at the Hess station across the street from Downtown Disney, they did not ask for a zip code when paying at the pump which leads me to my question. Do all gas stations in the United States or maybe just in Central Florida now ask for a zip code when paying at the pump? I am asking about the whole United States because during the summer my family & I drive to WDW, so obviously we will need to stop for gas & if they ask for a zip code I can tell my Dad to automatically pay inside the gas station. So if anyone can answer this I would appreciate it.
