You've likely noticed ISBNs beginning with the prefix "978." This is known as the ISBN prefix, and the introduction of ISBN-13 in 2007 started with this particular series. The surge in self-publishing since then has driven ISBN agencies to acquire additional ISBN blocks to cater to the booming demand from the book publishing sector. In response, the USA ISBN agency has rolled out the ISBN 13 with the new ISBN prefix 979 in 2020. In due course, ISBN agencies worldwide will also begin offering this new prefix.
One distinction to note between the 978 and 979 prefixes is their format availability. While the 978 prefix came in both ISBN-10 and ISBN-13 formats, the 979 prefix is exclusively available in the 13-digit format. As such, publishers cannot convert a 979 ISBN prefix into the ISBN-10 version. This modification ensures there's an ample supply of ISBN blocks for assignment and streamlines the ISBN issuance process.
For self-publishing authors in the US, Bowker, the official ISBN agency, provides the ISBN 979 prefix. If you're a book publisher or self-publisher outside the USA, you might think you're at a disadvantage. However, there's an economical alternative.
