FAQ: What Is The Number Cade On Books?

International Standard Book Number

The International Standard Book Number (ISBN) is a unique commercial book identifier that is assigned to each separate edition and variation (except reprintings) of a publication. The method of assigning an ISBN varies by country.


Gordon Foster created the Standard Book Number (SBN) in 1965, and the 10-digit ISBN format was published as international standard ISO 2108 in 1970. An SBN can be converted to an ISBN by replacing the digit “0” with a zero.


Each edition and variation (except reprintings) of a publication is given its own ISBN, which is made up of four parts (if it’s a 10-digit ISBN) or five parts (if it’s a 13-digit ISBN). Determining how to correctly separate a given ISBN is difficult because most of the parts don’t use a fixed number of digits.

How ISBNs are issued

The ISBN ranges assigned to each country are based on the country’s publishing profile. Some ISBN registration agencies are based in national libraries or within ministries of culture, while others are provided by non-government funded bibliographic data providers. A complete list of ISBN agencies can be found on the International ISBN Agency website.

Registration group element

The ISBN registration group element is a 1- to 5-digit number that can be separated by hyphens and is valid within a single prefix element, such as “978-1-….” The original 9-digit standard book number (SBN) had no registration group identifier.

Registrant element

The registrant element and a series of ISBNs are assigned to the publisher by the national ISBN agency; in most countries, a book publisher is not legally required to assign an ISBN. A listing of more than 900,000 assigned publisher codes is published and can be ordered in book form. For example, a large publisher may be given a block of ISBNs with fewer digits allocated for the registrant and many digits allocated for the registrant and many digits allocated for the registrant and
