The length of the registrant element is established within each registration group by ISBN

registration agencies in accordance with the needs of the publishing industry within their

designated area. The ranges assigned to each registration group must be established in

advance by the International ISBN Agency before determining distribution of ranges of

ISBNs to publishers within those groups.

EXAMPLE 1:

Test ISBN: 9786000000004

EAN.UCC prefix: 978

(registration group test segment): 60000

Registration group: (undefined and invalid)

Note:

 This test ISBN is not valid because the registration group test segment is within the

group 60000 to 69999, which has a specified group length of 0 (currently undefined).

EXAMPLE 2:

Test ISBN: 9780777777770

EAN.UCC prefix: 978

(registration group test segment): 07777

Registration group: 0

Note:

 This test ISBN is valid because the registration group test segment is within the

range 00000 to 59999, which has a specified registration group length of 1 (defined and

valid).

Table 3 illustrates the distribution of registrant element ranges and publication elements

within registration group 978 0. The registrant element ranges for use within each

registration group will be defined by the International ISBN Agency based on anticipated

publishing programmes for that registration group.
