I made a typo in the title or subtitle. Can I correct this?

If you've made a typo in the title or subtitle of your book during ISBN registration, the possibility of correcting it depends on the timing of your request. Immediate notification after submission is crucial. Contact us through the chat or by e-mail, so we can try to correct this. 

Our system is fully automated, which significantly limits the window for making changes. If you notify us right after submitting your book, there's a chance to correct the typo.

However, once the registration process is completed at Bowker, we are unable to make any changes to the title.
