How to find your order number
After you buy something on the Google Store, you get a confirmation email that you can use as a receipt. You can find your order number on this receipt.
If you can’t find your confirmation email, you can get a receipt online:
Visit pay.google.com/ and sign in with your Google account.
On the left, click Activity.
To get your receipt, select an order.
