ISBN group number

from Wikipedia, the free encyclopedia

The group number is part of the International Standard Book Number ( ISBN ). The group number is the second component of the ISBN (after the prefix 978 or 979) and identifies the language area , a state or a geographic region. The third part of the ISBN is the publisher's number . The group numbers are set by the International ISBN Agency based in London .

Length of the group number

The group number has one to five digits and is structured in the following number ranges :

Group
number		 From To
1-digit 0 5
7th 7th
2 digits 80 94
3 digits 600 649
950 989
4 digits 9900 9989
5 digits 99900 99999

This shows that the number range with the first digits 650–699 has not yet been assigned.
