Zip Code outside US for Apple Cash

Hi,

I'm trying to apply for Apple Cash since I understand there is an option to space out payments on some product purchases. I have to set this up under Wallet, and when I go to enter in my ZIP CODE, it only gives me the option to enter in numerical digits, while I live in Canada and my POST CODE consists of letters and numbers.

Even if I start an application for Apple Card and specify that I live in Canada under the country, it only gives me US States under the section State, and the same issue with the Zip Code.

I checked under my account and Im set up as Canada and my payment information also states a my billing address in Canada.

How can I give Apple more business as a non-US resident? Can someone help, please.
