International Standard Book Numbers (ISBN)

The ISBN Canada website is currently experiencing technical difficulties

Our technical team is actively working to resolve these issues. If you urgently require an ISBN number, please email the ISBN Canada team at isbn@bac-lac.gc.ca. We apologize for any inconvenience this may cause.

An International Standard Book Number (ISBN) is a 13-digit number that uniquely identifies each specific edition of a book or monograph from a publisher. ISBNs are used by publishers to sell and distribute their publications worldwide. ISBN Canada provides free ISBNs to eligible publishers and publications.
