ISBN Registration Groups
The first segment of every ISBN (after the EAN prefix 978 or 979) identifies the registration group — a country, language area, or territory managed by a national ISBN agency. There are approximately 160 active groups.
What is an ISBN registration group?
When the International ISBN Agency assigns a registration group, it allocates a digit or multi-digit prefix to a national agency. That agency then sub-allocates publisher prefixes within its range. Group 0 and Group 1 both belong to English-language countries; Group 2 covers French; Group 3 covers German; and so on. Groups with more commercial publishing activity have shorter numbers (and thus more publishers), while smaller markets get longer group numbers.
