ISO/IEC 15459-4:2014 PDF

Overview

ISO/IEC 15459-4:2014 defines a unique identification method for individual products and product packages using Automatic Identification and Data Capture (AIDC) media. The standard specifies the structure and rules for a unique character string (qualifier + string) that can be encoded in linear bar codes, two‑dimensional symbols, or other AIDC carriers attached to an item to support management, traceability and data lookup across supply chains.

Key topics and technical requirements

• Identity structure: An identity is composed of a qualifier and a string assigned by an identity issuer following Issuing Agency rules (ISO/IEC 15459-2 and -3).
• Character set: Identities must use upper‑case alphabetic characters and numeric digits from the invariant set of ISO/IEC 646.
• Length limits: Maximum of 50 characters per identity; recommendation to keep one‑line linear bar code content to ≤20 characters for practical AIDC use.
• Qualifier options: Examples include GS1 Application Identifiers (e.g., 8004, serialized GTIN using 01 + 21), ASC MH10 Data Identifiers (e.g., 25S, 25P + S, 3I), and specific object identifiers (OIDs) assigned under ISO/IEC 15459-4 for product and package identifiers.
• Classes of identity: Different identity classes are recognized across ISO/IEC 15459 parts (product, transport units, RTIs, groupings) so identities meet varied management requirements.
• Implementation: All AIDC technologies can encode the identity; application standards can be developed on the ISO/IEC 15459 identity as the primary key.

Applications and who uses it

ISO/IEC 15459-4 is intended for organizations that need item‑level identification and electronic data capture:

• Manufacturers and brand owners for product serialization and traceability.
• Retailers and logistics providers for inventory control, scanning, and automated receiving.
• Healthcare, aerospace, and defense sectors where precise item tracking and regulatory compliance are required.
• Issuing Agencies and system integrators implementing identity assignment policies and AIDC encoding. Practical uses include serialized product tracking, recall management, anti‑counterfeiting measures, quality inspection linkage, and linking physical items to database records via bar code or 2D symbol.
