How to get a customer's shipping information
If you are not selling a physical product on Gumroad but still need someone's shipping address, you basically have to force them to fill it in on the payment form. Luckily we have a quick, two-click option set up for you.
First go to your product's Preview page page.
Click Payment Form to bring down the custom field menu.
Now click Require Shipping Information and Update to force your customers to include shipping information on their purchases. All shipping information will be visible in your Customers tab.
If you don't wish to ship internationally, go to your product's Options tab and limit your sales to the United States.
