About the ISBN Letter Generator

Applying for an International Standard Book Number (ISBN) in Nigeria requires a formally drafted application letter to the National Library of Nigeria (NLN). The ISBN Letter Generator simplifies this process by instantly creating a correctly formatted, print-ready request letter for both individual authors and corporate publishers.

Whether you are figuring out how to get an ISBN in Nigeria for the first time or you are an established publisher managing a growing catalog, this free tool handles the administrative heavy lifting so you don’t have to worry about missing required information.

Tailored for Individuals and Publishers

• Individual Authors: Automatically format your personal details, contact information, and book metadata for all your titles at a time.
• Corporate Entities: Generate official requests using your registered CAC or SMEDAN business details. The tool includes built-in compliance checks for previous legal deposit history, allowing established publishers to request more numbers.

Key Features

• 100% NLN Compliant: Pre-formatted with the exact bureaucratic routing, addresses, and salutations required by the National Library of Nigeria.
• Digital Signatures: Choose to automatically render your name in a realistic digital signature font, or leave a perfectly sized blank space for a traditional wet-ink signature and company seal.
• Print-Ready Output: Generates a clean, watermark-free A4 document that you can print directly from your browser to take to your nearest National Library branch.

Stop stressing over official formatting. Simply input your publication details, print your standardized letter, and take the next step in your Nigerian book publishing journey.
