Official ISBN Agency Channel Partner
Books and eBooks should be assigned a unique ISBN number to be correctly identified. Every country has an ISBN Agency which administers their ISBN assignments and maintains the global standards. Bowker is the US ISBN agency and has contracts with agents, such as Publisher Services, to assist self publishers. The internet is full of many deceptive companies posing as the ISBN agency (ISBNAgency.com or isbnservices.com). Publisher Services is the largest authorized agent and has been providing ISBN numbers and barcodes to over 60,000 self publishers since 2004. Our toll-free phone number is posted on every page and we encourage our clients to call us at any time.
