I’ve been an Audible user for years, and this is a question I’ve seen pop up a lot. Unfortunately, Audible doesn’t allow direct transfers of books between accounts due to licensing restrictions. The books you purchase are tied to your Amazon account, and sharing or transferring them violates their terms of service. However, there’s a workaround if you’re in the same household—Amazon Household lets you share some digital content, including Audible books, with one other adult and up to four kids. It’s not a full transfer, but at least the other person can access your library. Another option is to use the ‘Send this Book’ feature for audiobooks you’ve purchased as gifts, but that only works for new purchases, not existing ones. It’s frustrating, but that’s the current system.
