In reply to the discussion: Latest blow to collecting Zip codes at check-out [View all]FarCenter
(19,429 posts)6. Some gas pumps in MA request zip code when you use a credit card.
Since it seems to vary by credit card, it would appear to be used to authenticate the user.
Gas purchases are a high fraud transaction, since all you have to do is skim and replicate another persons card -- easy for a waiter to do, for example. You can use blank plastic. It doesn't have to have credit card graphics or embossing to work in the pump.
Besides, Track 1 usually contains the cardholder's name.

It's kind of amusing/creepy to think they have a record of every food item you've purchased.
