Every published book you’ve ever picked up, whether a novel, biography, or textbook, has a unique number on the copyright page called an ISBN. This isn’t just a random code. It’s a book’s international identity, recognised across libraries, bookstores, and online platforms like Amazon. For authors and publishers in Nigeria, ISBN registration is not optional, it’s mandatory for publishing and distributing books legally and professionally. Without an ISBN, your book cannot be sold through bookstores, uploaded to major online platforms, or catalogued in libraries.
Yet, for many authors, ISBN registration in Nigeria feels confusing. Where do you go? How much does it cost? How long does it take? And how can you make the process smoother?
In this guide, we’ll break down everything you need to know about ISBN registration in Nigeria:
- what an ISBN is and why it matters,
- the official process for registering your ISBN,
- the costs involved,
- common challenges authors face,
- and how Ensuite9 helps simplify ISBN registration as part of our publishing support services.
By the end, you’ll have a clear roadmap to get your book’s ISBN quickly, affordably, and stress-free.
What is an ISBN and Why Do You Need It?
ISBN stands for International Standard Book Number. It is a unique 13-digit code assigned to every edition of a published book. Think of it as your book’s fingerprint, no two ISBNs are the same.
Why ISBN matters:
- Global recognition: Your book can be catalogued worldwide.
- Professional credibility: Without an ISBN, bookstores and libraries will not recognize your book.
- Distribution: Platforms like Amazon KDP, OkadaBooks, and IngramSpark require an ISBN.
- Sales tracking: ISBNs allow for sales and inventory tracking by retailers.
Each format of a book requires a separate ISBN. For example:
- A paperback version has one ISBN.
- An eBook version has another ISBN.
- A hardcover edition would need yet another.
In Nigeria, ISBNs are managed by the National Library of Nigeria (NLN). This means every author or publisher must apply through the NLN to obtain one.
ISBN Registration in Nigeria – The Authority
In Nigeria, the sole authority responsible for issuing ISBNs is the National Library of Nigeria (NLN).
- Head Office: Abuja
- Regional Offices: Lagos, Enugu, Ibadan, Kaduna, Kano, Jos, Port Harcourt, and others.
Whether you’re an independent author or a publishing company, you must apply through the National Library. Applications can be submitted in person at the NLN office closest to you. Some branches now allow limited email/online communication, but most still require physical submission of documents.
This official role ensures that every book published in Nigeria is properly documented, catalogued, and can be traced globally through its ISBN.
Step-by-Step Process for ISBN Registration in Nigeria
Here’s how to register an ISBN in Nigeria:
Step 1: Prepare Your Book Details
Before applying, you’ll need:
- Book title & subtitle
- Author name(s)
- Publisher name (can be self-published)
- Year of publication
- Number of pages
- Format (print, eBook, audio)
- A sample manuscript or first few chapters
Step 2: Visit the National Library of Nigeria (NLN)
Head to the NLN headquarters in Abuja or the nearest zonal office.
Step 3: Fill the ISBN Application Form
The form requires book details and publisher information. Independent authors can list themselves as the publisher.
Step 4: Pay the Required Fee
Fees are usually modest (₦2,500 – ₦10,000 depending on the number of ISBNs requested). Payment is made directly to NLN’s account.
Step 5: Submit Manuscript & Receipt
Submit your filled form, proof of payment, and a manuscript sample.
Step 6: Wait for Processing
Processing time can take 2–4 weeks, though it varies by branch.
Step 7: Receive Your ISBN & Barcode
Once approved, you’ll receive:
- A unique 13-digit ISBN
- Barcode (for use on the back cover)
- Confirmation letter from NLN
Cost of ISBN Registration in Nigeria
The cost of ISBN registration in Nigeria depends on:
- Whether you are an individual author or a registered publisher.
- The number of ISBNs requested (bulk ISBNs are cheaper for publishers).
- The book format (print vs. eBook vs. audio).
Typical costs in Nigeria:
- Single ISBN: ₦2,500 – ₦5,000
- Bulk (10 ISBNs): ₦15,000 – ₦25,000
- Barcode printing (if done externally): ₦1,500 – ₦3,000
Compared to international costs (where ISBNs can cost $100+), Nigeria’s ISBN system is relatively affordable.
Common Challenges Authors Face
While ISBN registration is straightforward on paper, many Nigerian authors encounter challenges such as:
- Delays: Processing sometimes exceeds 4 weeks.
- Multiple visits: Applicants may need to return to the library several times.
- Paperwork confusion: Forms and requirements are not always clear.
- Publishing in multiple formats: Authors often don’t realise each format requires a separate ISBN.
These issues can discourage new authors, leaving many manuscripts unpublished or distributed informally without ISBNs.
