When you make a purchase on Google Play, a confirmation email with your order information is sent to the Google Account you use. You can also find your order information on Google Pay by following these steps:
1. Visit Google Pay to view your recent transactions: https://pay.google.com/
2. Select an order to see your receipt. Your order number should look something like this: GPA.1234-1234-1234-12345.

Please note that if you are contacting our Support team for a purchase issue, the receipt must come directly from Google Play instead of PayPal or a bank statement since they do not have the required order number needed for verification.
