What It Is

ISBN Agency is a low-cost ISBN service platform operated by US-based Moodoo Productions. It provides self-published authors with international standard book numbers at prices far lower than official channels. Its core positioning is to help small and mid-sized authors lower the barrier to self-publishing. It has been operating for over 20 years and has served thousands of authors to date.

Core Features & Pricing

The platform's core product is retail ISBNs split from bulk purchases from Bowker, the official US ISBN governing body. The basic package includes an ISBN number, a free pre-formatted ISBN 13 barcode, a complimentary book promotion webpage worth $49, and listing guidance for channels like Amazon. Pricing is one-time payment: a single ISBN costs $39.99, the unit price drops to $34.99 when you purchase 2 or more, and bulk purchases qualify for additional discounts. There are no recurring annual fees or other hidden charges. The platform also offers additional extended publishing services including copyright registration, Library of Congress registration, book design, and one-on-one marketing consulting.

Pros & Cons

Advantages

• The most standout perk is its cost-effectiveness: you save at least $75 compared to buying directly from official channels, which is extremely friendly to independent authors who only need a small number of ISBNs.
• Fast delivery: all resources are sent to you via email immediately after ordering, and a 30-day full refund policy keeps purchasing risk low.
• The included listing guidance and promotion webpage are genuinely useful for new authors.

Disadvantages

• Because the ISBNs are purchased in bulk, all ISBNs are by default registered under Movement Publishing, the platform's affiliated entity. Authors can only use a custom press name for the book's content credits, and cannot register the ISBN under their own name. This creates a certain limitation for authors who want to build their own publishing brand.
• The website does not have a Chinese interface, which creates a barrier for authors based in China.

Suitable Users & Access from China

This platform is ideal for budget self-published individual authors who only need a small number of ISBNs for listing and sales. Professional organizations looking to build their own publishing brand are better off purchasing directly from official channels. The website is currently directly accessible from China's internet, and PayPal is the only supported payment method.
