Step 1 - Add Books to Your Trade

Enter ISBN - ISBN values are 10 or 13 characters long and can be found above/below the barcode or inside the book a few pages in, near all the copyright info. ISBN-13 values usually start with 978.

Scan the barcode or book cover - If you are on a mobile device, you can use the device's camera to scan the book's barcode or cover. Our proprietary software will recognize the barcode and enter the ISBN value automatically. If you are scanning the book cover, we will image match the cover and present a list of matching books. Simply select the book with the correct title and binding, and we'll enter its ISBN value for you.

Here is an example of the ISBN value (a few pages inside the book):

If your book does not have an ISBN value (no barcode and no ISBN inside), you can use our
PiggyBook app to scan the book cover.

With each scanned book you will receive a message stating whether the book was accepted and the offer price.

Once you have completed entering your books, it’s time to complete your trade. There is a minimum value of $6. A button will appear to take you to Step 2 - enter your PayPal email address.
