About ISBNs
An ISBN (International Standard Book Number) is a 13-digit number that uniquely identifies each specific edition of a book or monograph. Eligible Canadian publishers may request free ISBNs for printed books, ebooks, audio books and educational or instructional DVDs to distribute their works. Each format and edition of a publication must have its own ISBN. Once assigned, that ISBN is used internationally to identify that specific version of the book.

Use of artificial intelligence
By registering with ISBN Canada, you declare that your book was created by a human author. You may use AI tools only for limited support tasks, such as brainstorming ideas, checking grammar, or formatting your book. You must not use AI to generate the text, create the artwork, or translate the book. ISBN Canada does not issue ISBNs for works whose content is primarily generated by AI. LAC is currently reviewing its policy regarding the use of AI content creation and our guidance is subject to change.
Parts of an ISBN
The 13-digit ISBN starts with "ISBN" and is divided into five parts, with each part having a specific meaning. The parts of an ISBN are as follows and are written separated with hyphens:
- EAN (European article number) product code: the first three digits
- group identifier: a single digit that represents the country or language area in which the book is published
- publisher prefix: a number that identifies a particular publisher
- title identifier: a number that identifies a particular edition of a work
- check digit: a single digit that verifies that the previous digits are correct by using an algorithm
Until December 31, 2006, ISBNs were 10 digits. You may use both the 10-digit and 13-digit ISBN on a publication issued during that time.
Obtaining barcodes
The Canadian ISBN Agency does not provide barcodes. We advise publishers to contact their printer or graphic designer to discuss barcodes, as some of them offer a barcoding service.
About copyright
The ISBN does not provide copyright protection. Contact the Canadian Intellectual Property Office for questions about copyright.
