The last several times I have tried to pay at the pump it has told me my zip code is invalid. Any ideas? We haven’t changed address. We even called Capital One to verify that our zip code hadn’t changed and the one on file is what I am entering. Has this happened to any of you or am I just so unskilled that I can’t even pump my own gas? What’s in my wallet? A Capital One card that won’t buy gas at the pump.
