good response

easy, to the point, clearcut. No fussyness. No glaring distractions.

Great, very happy

Easy to move through the ISBN registering process.

ISBN direct went above and beyond after I recently purchased my ISBN number. I ran into some issues with uploading the cover art and I got an email that same day informing me of the issue and another email when the issue was resolved. They also contacted me about slashes being in the name of the contributor which is apparently not allowed. They remedied the issue to prevent any delays with the submission of our book. That is the work of people who actually care!! Kudos!

It was globally and dynamic strategic. More win

‏ Absolutely the best place to buy genuine international ISBNs!

‏I’ve purchased dozens of ISBNs from ISBNDirect over the past few years for both print and e-books, and every time the delivery is instant — the number and official invoice land in my inbox within seconds after payment. Prices are unbeatable, and payment options are super convenient (cards, PayPal, crypto).

‏A while ago, I needed to make some changes to one of my orders after purchase (update the title and publisher name). I contacted support expecting it might be complicated, but I was blown away by how professional and classy they were. They handled everything quickly, made all the requested modifications perfectly, and kept me updated throughout the process with genuine kindness and attention to detail.

‏That level of care and high professionalism is extremely rare these days. It turned me from a regular customer into a lifelong one.

‏If you’re a self-publisher or independent author, stop wasting money elsewhere — ISBNDirect is simply unmatched in price, speed, and customer service. Highly, highly recommended! Thank you for being awesome

I had an issue that I emailed them about late at night and had a response the very next morning and it was fixed

A generic product - identical to all other suppliers - but at a very good price (less than half the average market rate) with a really simple, straightforward and easy to follow process.

If you're a self-publisher who's dreaded the process and cost of securing ISBNs, your search is officially over. My personal experience with ISBNdirect has been nothing short of exceptional, and I genuinely cannot recommend them highly enough.

My first major win was seeing the price. I had been dreading the cost of ISBNs, knowing they can be prohibitively expensive elsewhere, but ISBNdirect offered truly competitive and reasonable rates. The immediate feeling of relief was immense, knowing I could secure everything necessary for my book without breaking my budget. It felt great to get a necessary, high-quality service at such a fantastic value.

My favorite part, however, was how simple and straightforward the whole process was. I expected to spend an hour navigating confusing forms and endless steps, but the interface was intuitive, the requirements were clear, and I secured my ISBNs in minutes with zero confusion or hassle. That saved time and effort made my whole publication timeline feel instantly less stressful. It’s rare to find a powerful administrative tool that respects your time so much.

In short, ISBNdirect delivered exactly what I needed: a great price and an incredibly simple, high-satisfaction experience. Stop wasting time and money elsewhere, and use ISBNdirect for your next publication!

Excellent service!! It's so fast and easy.

I love how easy it is setting up. However, I didn't see the best genre section for mine so had to go with closest. Other than that price isn't bad, easy to set up and get going, downloaded bar code also looked great as well on downloaded and pasted to documents. Also like the option to pay extra for marketing and that isn't a bad price either.

The service is very fast and professional.

Great and speedy service at an affordable price.

Quick and easy transaction

Fast and reliable service
