Publishing a book is a monumental achievement, but navigating the technical requirements can feel overwhelming. One of the first, most crucial steps is securing an International Standard Book Number (ISBN). This unique 13-digit code acts as your book's fingerprint, essential for tracking, distribution, and sales across global retailers like Amazon, Barnes & Noble, and local bookstores. To understand where obtaining an ISBN fits into the larger process, consider reviewing a practical author's guide on how to publish your books.
With numerous options available, from official national agencies to third-party resellers and full-service publishing houses, figuring out where to buy an ISBN can be confusing and stressful. This definitive guide demystifies the entire process. We provide a straightforward comparison of the top platforms, complete with direct links and screenshots to simplify your decision.
We will explore the pros, cons, and specific use cases for the best providers available. This resource will help you understand the critical difference between buying a single ISBN versus a block, what it means to be the 'publisher of record,' and how to choose the right path for your author journey, ensuring your book is set up for success from day one.
1. Bowker (MyIdentifiers.com): The Official US Source
For authors publishing within the United States, Bowker is the definitive and official source. When you ask where to buy an ISBN, this is the primary answer for direct ownership. Purchasing from its platform, MyIdentifiers.com, registers you or your publishing entity as the "publisher of record." This critical distinction gives you complete control over your book's metadata and future.
While the initial cost is higher than resellers, the investment ensures authenticity and bypasses potential issues with distributors who prioritize ISBNs from the official agency. It's the standard for serious self-publishers aiming to build a professional brand. Bowker offers single ISBNs, but its value shines with bulk packages, drastically reducing the per-unit price for authors with multiple projects.
Key Features & Pricing
- Official Publisher Status: Your name or company is listed as the publisher.
- Pricing Structure: A single ISBN costs $125. A block of 10 ISBNs is significantly more cost-effective at $295, dropping the per-unit price to just $29.50. Larger packages offer even greater savings.
- Integrated Services: Bowker offers bundled services, including barcode generation and metadata management tools, to enhance your book's discoverability.

| Pros | Cons |
|---|---|
| Establishes maximum control and credibility. | High cost for a single ISBN. |
| Recognized by all major retailers and distributors. | The website can feel corporate and less intuitive. |
| Significant long-term savings with bulk purchases. | Add-on services increase the overall cost. |

3. ISBN Agency: The Budget-Friendly Reseller
For authors prioritizing speed and affordability, ISBN Agency presents a compelling alternative to official channels. As a reseller, it offers a streamlined path for those wondering where to buy an ISBN without a significant upfront investment. This platform is particularly attractive to self-publishers on a tight budget who need a number quickly to get their book to market and are less concerned about being the official publisher of record.
The primary trade-off is publisher status; your book's metadata will list "Movement Publishing" as the publisher, not you or your imprint. While this is a critical consideration for brand-focused authors, many find the low cost and value-added perks, like a free barcode and promotional webpage, to be a worthwhile compromise. Understanding how to get an ISBN for a book through resellers like this is key for new authors exploring their options.
Key Features & Pricing
- Publisher of Record: Your ISBN is registered under 'Movement Publishing.'
- Pricing Structure: Offers highly discounted single ISBNs that include a free barcode, a significant saving compared to official agency pricing. Package deals provide even greater value.
- Bonus Features: Each purchase includes a free barcode (often an extra charge elsewhere) and a simple webpage for early book marketing efforts, delivered quickly via email.
Website: https://www.isbnagency.com/
| Pros | Cons |
|---|---|
| Extremely cost-effective for single ISBNs. | You are not listed as the publisher of record. |
| Very fast email delivery of ISBN and barcode. | May not be accepted by all major distributors. |
| Includes valuable extras like a free barcode. | Less control over your book's official metadata. |
4. ISBNforBooks.com
For authors seeking a fast, no-frills solution to the question of where to buy an ISBN, ISBNforBooks.com offers a streamlined and affordable alternative. The platform is designed for simplicity, providing instant digital delivery of both the ISBN and its corresponding high-resolution barcode. This service is ideal for writers who need to quickly list their book on platforms like Amazon or Barnes & Noble and are less concerned with establishing a formal publishing imprint.
The key trade-off for its competitive pricing is publisher attribution. Instead of your name, the publisher of record will be listed as 'Independent Publisher' or a similar generic designation from their block of purchased ISBNs. While this may not be suitable for authors building a brand, it's a practical and cost-effective choice for single projects or for testing the market with a new title without a significant upfront investment.
Key Features & Pricing
- Instant Delivery: Receive your ISBN and barcode immediately after purchase.
- Affordable Pricing: Single ISBNs are offered at a much lower price point than official agencies, making it accessible for any budget.
- One-Time Fee: There are no renewal fees, and the ISBN does not expire, providing a permanent identifier for your book format.
- Included Barcode: A high-resolution barcode image is included with the purchase, saving you an additional step and expense.
Website: https://isbnforbooks.com/buy-isbn-number/
| Pros | Cons |
|---|---|
| Very competitive and affordable pricing. | Your name is not listed as the publisher. |
| Instant digital delivery is convenient for quick turnarounds. | May not be recognized by certain distributors or retailers. |
| Simple, straightforward purchase process. | Limited brand control for the author. |
5. ISBN Services
ISBN Services presents a tiered approach for authors wondering where to buy an ISBN, offering both basic and custom packages. This platform is geared toward speed and affordability, making it a viable option for publishers on a tight budget or timeline. The key distinction lies in their "custom" ISBN, which allows you to register your own publishing name, similar to buying direct, but through their streamlined interface.
While the fast processing and included barcodes are attractive, it's crucial to understand the limitations. Their basic ISBNs are pre-owned and may list one of their partner companies as the publisher, which can cause issues with certain platforms like Amazon's KDP. Therefore, authors seeking full control and brand recognition should opt for the custom package. Understanding how to get an ISBN number for my book and its implications is key before choosing a reseller.
Key Features & Pricing
- Tiered Packages: Offers a choice between a "Basic ISBN" and a "Custom ISBN" to fit different needs and budgets.
- Pricing Structure: A Basic ISBN starts at a lower price point, while a Custom ISBN, which includes personalized publisher data, is priced higher but remains competitive.
- Included Barcodes: All ISBN packages come with high-resolution, print-ready barcodes at no extra charge, simplifying the pre-publication checklist.
- Quick Turnaround: The service prides itself on fast processing times, often delivering ISBNs and barcodes within a short period.
Website: https://www.isbnservices.com/isbn-numbers/
| Pros | Cons |
|---|---|
| Affordable entry-level options for basic needs. | Basic ISBNs may not be compatible with KDP. |
| Fast processing and delivery of numbers. | The publisher of record is not the author on basic plans. |
| Barcodes are included with all purchases. | Less control compared to buying direct from Bowker. |
6. One Book at a Time
For authors looking for more than just a number, One Book at a Time positions itself as a comprehensive publishing partner rather than a simple reseller. If you're asking where to buy an ISBN but also need guidance on printing, design, or distribution, this platform integrates the ISBN process into a broader suite of services. Their model is built around personalized assistance, making it an excellent choice for first-time authors who feel overwhelmed by the technicalities of self-publishing.
This approach distinguishes them from transactional sites by focusing on the author's entire journey. Instead of just selling an ISBN, they offer a support system that includes book printing and other crucial publishing resources. This hands-on service is ideal for writers who value having a dedicated contact to help navigate the complexities of bringing a book to market, ensuring all the pieces fit together correctly.
Key Features & Pricing
- Integrated Publishing Support: Provides ISBNs as part of a larger package including book printing and other publishing assistance.
- Personalized Service: Caters to authors seeking one-on-one guidance throughout the publication process.
- Pricing Structure: Pricing details are not listed publicly on the site; authors must inquire for a custom quote based on their specific needs.
Website: https://onebookpub.com/isbn/
| Pros | Cons |
|---|---|
| Personalized, hands-on service for authors. | Pricing details are not specified online. |
| A one-stop shop for ISBNs and printing services. | Less suitable for authors just needing an ISBN. |
| Excellent resource for those new to publishing. | The process requires direct contact for a quote. |
7. ISBN Barcodes: The Barcode Image Specialist
It's a common point of confusion: an ISBN is the number, while a barcode is the scannable image of that number. While you may wonder where to buy an ISBN, you will also need the corresponding barcode image for your physical book's back cover. This is where a service like ISBN Barcodes comes in. It doesn't sell the numbers themselves but specializes in generating the high-resolution, retail-compliant barcode images you need after you've acquired your ISBN.
This platform is crucial for authors who have already purchased their ISBN from an official agency like Bowker but did not get a barcode bundled with it. ISBN Barcodes provides a fast, direct solution, delivering the necessary image files instantly via email. This ensures your book designer has the correct file formats (EPS, JPEG, etc.) needed to integrate the barcode seamlessly into your cover design, making your book ready for physical retail shelves without any technical hitches.
Key Features & Pricing
- Barcode-Only Service: This platform focuses exclusively on generating EAN-13 barcode images from your existing ISBN.
- Instant Delivery: Barcode images are generated and delivered via email immediately after purchase, eliminating production delays.
- Multiple File Formats: You receive the barcode in several high-resolution formats to ensure compatibility with any design software.
- Pricing: A single barcode image typically costs around $10-$15, making it a very affordable and specific solution.
Website: https://isbnbarcodes.org/where-to-get-isbn-numbers/
| Pros | Cons |
|---|---|
| Quick, instant, and efficient service. | Does not provide the actual ISBN, only the barcode image. |
| Delivers high-resolution, retail-ready files. | A necessary extra step and cost for some authors. |
| Supports multiple formats for design flexibility. | The website's primary focus is not on ISBN acquisition. |
8. BookScouter
While you can't directly buy an ISBN from BookScouter, it's an indispensable tool for understanding the value and lifecycle of a book once its ISBN is assigned. This platform functions as a price comparison engine, aggregating offers from dozens of vendors for buying, selling, or renting books. For an author or publisher, this provides crucial market intelligence. By entering an existing book's ISBN, you can instantly see its current market value across various platforms.
Using BookScouter helps you research competitor pricing, understand demand for specific genres, and see how different book formats are valued in the secondhand market. Although not a place where to buy an ISBN directly, it’s a strategic resource for making informed publishing and pricing decisions. It’s particularly useful for authors in the textbook or academic space to gauge the competitive landscape.
Key Features & Pricing
- Price Comparison Engine: Aggregates real-time buyback, rental, and purchase prices from over 30 vendors.
- Free to Use: The core service of comparing prices is completely free for all users.
- Market Research Tool: Provides direct insight into a book's resale value, helping you price your own work competitively.
Website: https://bookscouter.com/
| Pros | Cons |
|---|---|
| Excellent for market research and competitor analysis. | Does not sell ISBNs; it is a secondary tool. |
| User-friendly interface and mobile app. | Primarily focused on existing books, especially textbooks. |
| Completely free for basic price comparison. | Not a direct step in the publishing process itself. |
9. ISBN International: The Global Authority
While you cannot directly buy an ISBN from this source, ISBN International is the ultimate global authority that governs the entire system. Think of it as the United Nations of ISBNs; it doesn't serve individual authors but coordinates the national agencies that do. Its primary role is to provide definitive information and direct you to the correct, official ISBN provider for your specific country. This is an essential stop for any author publishing outside the major markets like the US or UK.
This website is crucial because it ensures you avoid scams and find the legitimate agency for your region, from Australia to Zimbabwe. Using their official directory is the safest way to guarantee you are purchasing a valid ISBN that will be recognized worldwide. For international authors wondering where to buy an ISBN, this site is the most reliable starting point before making any purchase.
Key Features & Pricing
- Official Agency Directory: Its most valuable feature is the comprehensive, searchable directory of every national ISBN agency on the planet.
- Pricing Structure: There is no cost. This is an informational resource, not a commercial vendor. Pricing will depend on the national agency it directs you to.
- Authoritative Guidance: Provides official documentation, FAQs, and standards on the correct usage and application of ISBNs globally.
Website: https://www.isbn-international.org/
| Pros | Cons |
|---|---|

Think of it as the authoritative library and navigational guide for anyone asking where to buy an ISBN. Its primary function is to educate authors on the correct procedures and standards surrounding ISBN usage, ensuring they follow best practices from the start.
The site is an indispensable resource for understanding the technicalities behind the system. Instead of selling ISBNs directly, it acts as the official gateway, directing US-based authors to Bowker’s MyIdentifiers.com for the actual purchase. This ensures users are funneled to the correct, legitimate source, preventing them from unintentionally buying from unaccredited resellers. For authors new to the process, starting here clarifies many common questions before making a purchase. You can learn more about how ISBN.org fits into the broader process of how to get an ISBN number.
Key Features & Pricing

- Directs to Official Seller: Links users directly to Bowker (MyIdentifiers.com) for purchasing, eliminating the risk of using unofficial channels.
- No Direct Sales: The website itself does not have a pricing structure; it is purely informational and a directory to the official US ISBN agency.
Website: https://www.isbn.org/
| Pros | Cons |
|---|---|
| Provides the most reliable and official information. | You cannot purchase an ISBN directly on the site. |
| Helps authors avoid common pitfalls and scams. | The site's primary function is to redirect users elsewhere. |
| Clarifies complex rules around ISBN assignment. | May feel like an unnecessary extra step for experienced authors. |
11. ISBN Services (Custom ISBN)
For authors seeking a middle ground between official agency pricing and standard reseller limitations, ISBN Services presents a compelling "Custom ISBN" option. This product addresses a key pain point for serious self-publishers: having their own name or imprint listed as the publisher of record. When you ask where to buy an ISBN with this level of personalization without the high cost of Bowker’s single-unit price, this platform is a strong contender. It effectively bridges the gap, offering direct publisher recognition at a more accessible price point.
This service is ideal for authors who want to establish their brand identity from their very first book. The package includes the custom-assigned ISBN and a high-resolution barcode, ensuring your book is ready for both online retailers and physical bookstores.

It offers an immediate solution for where to buy an ISBN when speed and budget are the main concerns.
The key trade-off with this service is in the publisher-of-record listing.

Making the Right Choice for Your Author Journey
Navigating the landscape of ISBN acquisition can feel overwhelming, but it boils down to one foundational question: What are your long-term goals as an author? Your decision on where to buy an ISBN is not merely a logistical step; it's a strategic choice that directly impacts your book's identity, distribution potential, and your control over your publishing brand. As we've explored, the path you choose should align perfectly with your budget, desired level of involvement, and professional aspirations.
Key Takeaways for Choosing Your ISBN Provider
To simplify your decision, let's distill the options into their core value propositions. Think about which of these scenarios best describes your needs as you move forward.
-
For Maximum Control and Brand Ownership: If you see yourself publishing multiple books and want to build a publishing imprint under your own name, buying directly from your official national agency, such as Bowker in the US, is the unequivocal best choice. While the upfront cost is higher, you gain full control as the publisher of record, a crucial asset for serious career authors.
-
For Speed, Simplicity, and Affordability: If your primary goal is to get your book published quickly and cost-effectively, and you aren't concerned with being the publisher of record, a reputable reseller like ISBN Agency or ISBNforBooks.com is a practical and efficient solution. This is ideal for one-off projects or authors prioritizing a low-barrier entry into publishing.
-
For a Hybrid Approach: For authors who want to retain brand identity without the high cost of a block of 10 ISBNs, innovative options like a custom ISBN from providers such as ISBN Services offer a compelling middle ground. This allows your name or imprint to be associated with the ISBN, blending affordability with brand recognition.
Your Actionable Next Steps
Before you make a purchase, take a moment to evaluate your project's specific requirements. Are you publishing an ebook, a paperback, and a hardcover? Remember, each unique format requires its own distinct ISBN. Factor this into your budget and decision-making process.
Once you’ve secured your ISBN, the next phase of your author journey begins. This is the perfect time to optimize other aspects of your workflow. Many successful authors streamline their manuscript creation process to save time and boost productivity. For instance, exploring tools like dictation software for writers can fundamentally change how you draft, allowing you to capture ideas faster than you can type.
Ultimately, purchasing an ISBN is the official starting pistol for your book's life in the marketplace. It transforms your manuscript from a personal project into a professional product ready for readers. By carefully considering your goals against the options available, you can confidently choose the right partner to help launch your work into the world.
