The international agency oversees the group agencies. Group agencies administer the interests of the ISBN system in a national, regional, linguistic or other division.
See the ISBN agencies page for a list of the world's ISBN agencies, including contact information.
The group agencies are responsible for allocating publisher identifiers to participating publishers, and to supply them with the range of title identifiers allocated to them. Group agencies are responsible for maintaining registers of ISBN and collating statistics and reports on ISBN usage within their jurisdictions. The training, education and promotion is the responsibility of group agencies.
Publishers are responsible for assigning ISBN to their own individual publications in accordance with the proper regulations and from the lists of individual ISBN supplied by their group agency.
The group agency makes such individual ISBN to publishers in accordance with anticipated usage by the publisher. As the volume of available ISBN is not infinite, the length of the publisher id and blocks of ISBN supplied to individual publishers is made on the basis of a publishers historical publication activity as well as anticipated future use.
