Ok so my mom recently won an iPad mini.she created an apple I'd .but when I wanted to download app from the App Store, I had trouble with the billing info part.i was trying to download a free app so I put my payment method as none, the other stuff was fine except for the postcode. I set the account so Singapore but it still said the postcode was invalid . It accepted the address and phone number only the postcode was invalid. Pls help
Make sure your postcode has 6 digits.
Ok the problem has been solved. I just had to spam it , and it was 6 digits
