REISSUE OF ISBNs

If you have purchased ISBNs in the past and have lost or mislaid your numbers you can have them reissued here. Unused ISBNs remain valid indefinitely.

If you are using this site for the first time you need to register before you can purchase, regardless of whether you have purchased ISBNs offline in the past via the ISBN Agency for UK & Ireland.

Once you have completed your payment, the order will be processed and a complete list of your ISBNs e-mailed to you within five working days. The list of ISBNs will be sent to the e-mail address you used in the registration form.

We can only reissue your ISBN’s if they were allocated by the ISBN Agency for the UK & Ireland. If you require a reissue of ISBN’s which were allocated outside of the UK please contact your national ISBN Agency.

Important Information

As part of our service the list you will receive also shows the titles registered with Nielsen Book. Where there is no title, this means only that no data has been sent to Nielsen Book, not necessarily that the ISBN is unused. You will need to check your own records to make sure the number is free.

The ISBN Agency cannot be responsible for re-use or duplication of ISBNs.
