Unique Identifiers

The UK ISBN Agency is run by Nielsen Book and is responsible for assigning ISBN Publisher Prefixes to publishers based in the UK or Republic of Ireland. We are therefore in the unique position of having a direct relationship with over 40,000 publishers which allows Nielsen Book’s database of titles and publishers to be the most up-to-date and comprehensive. 

As from July 2010, the UK ISBN Agency is also responsible for assigning ISBN prefixes to publishers based in any of the following British overseas territories: Anguilla, Bermuda, British Virgin Islands, Cayman Islands, Montserrat, Turks and Caicos.

The agency:

  • Allocates ISBN Publisher Prefixes to eligible publishers based on the information provided by the publisher

  • Maintains a database of publishers and their prefixes for inclusion in the Publishers International ISBN Directory
  • Encourages and promotes the use of the Bookland EAN bar code format
