Description

All 13 digit EANs with the 979 prefix are validating as ISBNs (ISBNValidator). There are 2 issues with this.

1. 979-0 prefixed numbers are allocated to the ISMN agency and represent music works. https://www.ismn-international.org/whatis.html
2. 979-[2-9] are unassigned at present, that is they have not yet been allocated to a country agency (or another authority).
   see attached xml (from www.isbn-international.org/export_rangemessage.xml RangeMessage.xml ) for the current valid ranges for ISBN
   and https://en.wikipedia.org/wiki/List_of_ISBN_identifier_groups#Identifiers_of_the_979-_prefix

An example unassigned 'ISBN' is 9792222222223
