A valid EAN code ensures the official identification of the product and its availability across international indexing and referencing systems.

Objectives

• Provide unique and standardized identification for the ebook throughout distribution, commercial management, cataloging, and archiving workflows.

Implementation

• Display the EAN or ISBN-13 code in the legal notices, product page, or technical metadata. This information is mandatory for commercial publications.
• Ensure the EAN code complies with GS1 specifications and is included in ONIX metadata for interoperability between editorial management systems.

Control

• Verify that the full 13-digit EAN code is present in the EPUB/PDF metadata, on the digital cover, and within the book’s technical notices.
