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.
Sell books by entering 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.
