I didn't have to when I used the POFQ laundry.
I've had trouble in the past trying the 00 trick, and I discovered that the reason was because the zip code created by adding the 00 did not actually exist! But after doing a zip code lookup I did find that a 01 did exist for me, so I use that instead and haven't had any issues since.When I filled up at a U.S. Costco attendant told me to just put corresponding numbers for letters of postal code. It worked. I don't know if it's just at Costco that it works, or all US gas stations. When driving around Florida I get a Hess cash/gift card to make life easier.
I'll have to try that. So glad the laundry machines don't require postal codes. Gas station is bad enough!! Guess at Disney they have so many international visitors using a CC machine that requires a U.S, postal code just isn't feasible.I've had trouble in the past trying the 00 trick, and I discovered that the reason was because the zip code created by adding the 00 did not actually exist!
