See Section 2: Gather Your Resources for more information about ISBNs. ISBNs for e-books are entered in a different part of the process.
If you are not brining your own ISBN, Amazon will assign one for you. An Amazon-assigned ISBN can not be used outside of Amazon.

If you are bringing your own ISBN, copy and paste it into the relevant box.
Enter the imprint name exactly as it appears in your ISBN registration. Again, copy and paste to reduce the potential for errors. If you are using the ISBN provided by Amazon, you can leave this section blank.
