but I'm OK
I noticed that neighbouring states of the Canadien border do not enforce this - yet - but all told me it's coming.
I read that entering a 5 Zeros may work, or padding with Zeros the numbers from the postal code - e.g. 10607 in my case, may work. We'll try it for sure this summer on our annual trek to Myrtle Beach.
On one trip, our Amex stopped working, as it was deemed suspicious we were buying so much gas in 1 day... a phone call fixed that.
