No, Amazon does not release sales numbers for individual books. However, there are a few ways to estimate how many copies a book has sold on Amazon.
First, you can look at the Amazon Best Seller Rank (BSR) for a book. This is a number that Amazon assigns to every book on the site, which is based on how well the book is selling. The lower the number, the better the book is selling. You can find a book's BSR on its Amazon page, on the right-hand side under the "Product Details" section.
Keep in mind, however, that the BSR can fluctuate a lot, so it's not a completely accurate measure of sales. Also, different books will have different BSRs depending on how popular they are in different categories. For example, a romance novel might have a lower BSR than a mystery novel because there are more romance novels being sold overall.
Another way to estimate sales is to look at the number of reviews a book has. More reviews generally means that more people have bought and read the book. You can also look at the ranking of a book in its category. A higher ranking means that it's selling better than other books in that category.
Of course, there's no way to know for sure how many copies of a particular book have been sold on Amazon, but these methods can give you a general idea.
