Your Book's ISBN

What is an ISBN?

A 10 or 13 digit number that can be found on the back cover or inside the front cover of almost all books.

You may enter the ISBN with or without the dashes, and don't leave off the leading zeros. Sometimes an ISBN can end with an X.

CASH4BOOKS® will accept either the 10-digit or the 13-digit ISBN.
Example: 9781888799972

Use the 10 digit or 13 digit ISBN from your book

13-digit ISBNs should start with the numbers 978. Your book may have a 10-digit ISBN, or a 13-digit ISBN, or both (if your book has both, only enter the 13-digit number).
