Question

Why does the gas station ask for zip code when paying with a credit/debit card at the gas pump?

Answer 1

They claim it's for "security" reasons, but actually, it's because they're just d**n nosy b******s.

Answer 2

security measure. To make sure the person that owns the card is actually the one using it.

Answer 3

To measure tax..

like in Denver its 80215, if you input that the tax is 7.6%

but, if you put in 80228, which is Jefferson Cnty its 2.6%

i do that at my job, i try to save customers money, so i always use Jeffco

=)

Hope that helps

Answer 4

They say its for security.... but I think they do it to study there customer base to know how and where to advertise. As the person said above for tax=no way beacause tax is included in the price of gas and it is charged federal and by state, not by county.
