Standard Address Number (SAN)
✨ A SAN isn’t necessary for every author, but it can set you apart as a professional publisher ready to do business on a larger scale.
📨 SAN (Standard Address Number)
The Standard Address Number (SAN) is a unique seven-digit identifier used to signify a specific address of an organization in (or served by) the publishing industry. It is an American National Standard, This system, initiated and maintained by R.R. Bowker , has become THE identification code for electronic communication within the industry.
This system, initiated and maintained by R.R. Bowker, has become the official identification code for electronic communication within the publishing industry.
It is the method used by PUBNET, X*NET, and PubEasy.com systems and is required in all electronic data interchange communications using the Book Industry Systems Advisory Committee (BISAC) EDI formats.
The SAN itself has no functional meaning—it merely defines an address. It becomes meaningful only when used to identify customers for electronic ordering transmissions, voice recognition ordering systems, teleordering, billing, or shipping account numbers.
The use of SAN significantly reduces problems caused by non-standard numbering systems, such as billing errors, books shipped to incorrect addresses, payment mistakes, and return processing errors.
Entities using SAN include book and journal publishers, wholesalers, distributors, book retailers, college bookstores, libraries, schools, universities, paper and cloth manufacturers, printers, and binders, as well as others in the book and journal manufacturing chain.
Why the SAN Matters
Efficiency – Speeds up ordering and reduces errors in shipping and billing.
Professional Recognition – Signals that you are an established publisher in industry databases.
Library & Distributor Access – Many large retailers and libraries prefer working with publishers who have a SAN.
Streamlined Communication – Eliminates the need for long addresses or repeated contact information.
How SANs Work
A SAN is a 7-digit number assigned to a publisher, bookseller, library, or vendor.
It is issued and maintained by Bowker, the official U.S. agency for SANs.
Example format: 123-4567
Each number is unique and tied to your publishing identity.
📖 ISBN vs. 📨 SAN — What’s the Difference?
ISBN (International Standard Book Number) identifies a specific book title or edition. Every format (hardcover, paperback, eBook) needs its own ISBN.
SAN (Standard Address Number) identifies a specific organization or address in the publishing industry (like a publisher, distributor, or bookstore).
👉 Think of it this way:
ISBN = Which book is it?
SAN = Where is it going?
Both are valuable, but they serve very different purposes. ISBNs are essential for every published book, while SANs are most beneficial for publishers and distributors managing large-scale orders or electronic data interchange (EDI) systems.
Important Notes
SANs are optional but highly valuable for publishers planning to scale their distribution.
A SAN is not tied to one book—it represents your publishing entity as a whole.
You must renew or update your SAN if your publishing business address or ownership changes.
