The ZIP code requested during the payment method setup is typically the postal code associated with your billing address. In the United States, ZIP codes are indeed usually 5 digits long. However, some systems may ask for the last 3 digits of your ZIP code, which is known as the ZIP+4 code.
If you're encountering issues with entering your ZIP code, please ensure that you are entering the ZIP code that matches the billing address for your card. If the system specifically asks for a 3-digit ZIP, it might be referring to the last three digits of your standard 5-digit ZIP code.
If you've tried this and it still doesn't accept the information, there might be an issue with the payment system or it could be a misunderstanding of the instructions. In that case, I would recommend reaching out to the support team for clarification on the exact format they need for the ZIP code. If you need assistance with contacting support or anything else, please let me know!
