To search your Amazon order history, open Amazon on the web and click Orders in the top right corner. Just above your list of previous orders, you’ll see a search box. Enter your search terms in this box and click Search Orders. Your search results will appear in a list below the search box.

On the iPhone, you’ll find the hamburger button in the lower-right corner. In the menu that appears, tap “Your Orders.” On the next screen, you’ll see a list of orders you’ve placed through Amazon in reverse chronological order (most recent at the top) by default.
