I am UK based #fullmonzo.
So when in the United States, 7-Eleven stores (Petrol stations) prompt for a valid “zip code” when using chip and pin or mag stripe. Zip codes are digits only. The man at the desk suggested using the numbers of my postcode and pad out with zeros. It always came back with ‘invalid zip’. Now I don’t think the transaction was every referred back to Monzo so I think any “valid” US zip code would work.
I pulled out the reserve Halifax Clarity Card and as soon as the man at the desk saw this he said “don’t bother trying that”. I don’t know if he ever got any success with the pad-zeros idea.
In the end I had to pay cash (!!).
Didn’t have a single problem with the card anywhere else in the US.
I raised on the Monzo chat and got the below answer - which appears to be lots of English words strung together…
Anyone else faced and solved the problem i.e. Monzo chip and pin at 7-Eleven stores buying Petrol?
I’m so sorry for the delay in getting back to you. That’s a great question. The best thing to do in these types of situations is to process the transaction with the tellers, due to difference in the UK postal codes and US zip codes. I realise it’s a bit inconvenient, but, working with the teller should require chip and pin normally.
Hope this helps.
