000278

000278 is a reference code that appears in various contexts, most notably within the **International Standard Book Number (ISBN)** system. Specifically, it serves as a **registration group identifier** for publishers in certain regions, particularly in the **United States and Canada**. ISBNs are unique numeric identifiers assigned to books and book-like publications to facilitate organization and distribution in the publishing industry.

The code 000278 is part of the **ISBN-10** format, which consists of a 10-digit number divided into four segments: the registration group, the registrant, the publication, and a check digit. In this case, 000278 indicates the publisher’s registration group within the **Bowker Group**, the primary ISBN agency for North America. Publishers within this group receive a unique registrant code to assign to their specific titles.

While 000278 itself does not correspond to a specific book, it helps identify the publisher’s affiliation within the ISBN system. The full ISBN includes additional digits that uniquely identify a particular edition of a book. ISBNs have since been largely replaced by the **ISBN-13** format, which uses a 13-digit barcoded system, but the legacy ISBN-10 system remains in use for some older publications.

Beyond publishing, the code 000278 may also appear in other standardized numbering systems, such as **product or inventory codes**, depending on the industry. However, its most recognized use remains within the ISBN framework. For accurate identification of a specific book, the full ISBN number must be consulted.
