You might be a publisher, a self-publishing author, or simply a curious person who wants to get an ISBN number online in Nigeria. If you fall into any of these categories, you’re in the right place.
People today assume ISBNs are old-fashioned or unnecessary, especially in this age of social media marketing and digital publishing. But that’s far from the truth. ISBNs remain a key requirement for book distribution, listings on platforms like Amazon, and bookstores.
In fact, it’s what officially distinguishes your book as a published work rather than just a digital file or printout.
In Nigeria, the National Library assigns an ISBN (International Standard Book Number) to books, e-books, and other book-like materials, helping each one stand out and be easily tracked internationally.
It is important as it is what gives your book a recognized identity in the global publishing ecosystem.
In this article, you’ll discover everything you need to know about how to get an ISBN online in Nigeria, the requirements, cost, and practical tips to make your application faster and smoother.
What is an ISBN Number?
An ISBN (International Standard Book Number) is a unique 13-digit number assigned to books and book-like products published internationally, created to identify and differentiate them on a worldwide scale. Just like every person has their fingerprint and identity, published books also have their identity.
The purpose of ISBNs is:
- For publishing your books, whether printed or electronic.
- To provide a standardised method of cataloguing.
- For monitoring individual publications.
- To allow for worldwide recognition.
- To access publications across many platforms and marketplaces.
Interestingly, ISBNs are never assigned to music, performances, or images like art prints or photographs. They are also not assigned to magazines, academic journals, or other periodicals.
They are for monographic publications — texts that stand on their own as a product, whether printed or digital (audio or electronic).
When to Get an ISBN Number?
Below are scenarios people need an ISBN;
- To sell printed books: You need an ISBN for stores and distributors to accept your book.
- To look professional: An ISBN makes your book appear official and credible to readers, libraries, and booksellers.
- To reach more platforms: You need your own ISBN if you plan to sell your book in multiple bookstores or online platforms.
When an ISBN Might Be Optional
You might not need an ISBN if;
- Your book is only an e-book: Some e-book platforms don’t require an ISBN. You can still assign one if you want, but many platforms identify your book using their own internal tracking system instead.
- You sell only on one platform: For example, Amazon KDP gives you a free ISBN when you publish exclusively through them, so you don’t need to buy one separately.
