List of ISBN registration groups

The registration group or identifier group is the second element in a 13-digit ISBN (first element in a 10-digit ISBN) and indicates the country, geographic region, or language area where a book was published.^[1] The element ranges from one to five numerical digits.^[1]

In 2007, the length of an ISBN changed from 10 to 13 digits, and a new 3-digit prefix (978 or 979) was added in front of 10-digit ISBNs.^[2] The following registration groups are compatible with or without a 978- prefix:

• 0–5
• 600–639
• 64–69
• 7
• 80–94
• 950–989
• 9900–9989
• 99900–99999

The following must have a 979- prefix:

• (979-0 is reserved for International Standard Music Numbers for sheet music)^[3]
• 979-10 through 979-13
• 979-8

Shorter registration group numbers are generally used for countries or regions with greater publishing volume.^{[citation needed]} Because a longer number leaves room for fewer publishers and ISBNs, several countries have more than one number assigned. On the other hand, some countries (Australia, Switzerland, Fiji) have no unique number because they fall in a broader geographic region or language area.

Notes

1. Note that "language area" does not mean all books with the identifier are written in that language, only that the geographic area is identified as such; thus, books in Breton are identified as French language books, and books in Navajo are identified as English language books, etc.
2. In practice, this group is mostly used by some subsidiaries of VDM Publishing with registered addresses in "Beau-Bassin, Mauritius".
