ISO 22742:2026

Overview

ISO 22742:2026 - Packaging - Linear bar code and two-dimensional symbols for product packaging provides international guidelines for the design and use of product package labels containing linear bar codes and two-dimensional (2D) symbols. Published by the International Organization for Standardization (ISO), this standard establishes minimum requirements for encoding critical product information using machine-readable (e.g., bar code and 2D symbol) and human-readable formats. The document is designed to support item identification, inventory control, picking, and other supply chain processes at the product package level across diverse industries.

ISO 22742:2026 facilitates seamless data exchange between trading partners by standardizing label content, formatting, symbology selection, and placement. While it offers recommendations for label design, placement, and data representation, it does not prescribe specific label dimensions or the precise location of markings, leaving these details to be mutually agreed upon by suppliers and partners.

Key Topics

• Label Design and Content: Specifies minimum requirements for encoding data in linear bar codes, 2D symbols, and human-readable forms, ensuring consistency and clarity.
• Symbology and Data Carriers: Provides recommendations on the selection and use of linear (e.g., Code 128, EAN/UPC) and two-dimensional (e.g., Data Matrix, QR Codes, PDF417) bar code symbologies, considering compatibility with various scanning hardware.
• Data Formatting: Offers guidance on structuring both coded and human-readable information, including mandatory and optional data elements such as item identification, quantity, traceability, and supplier information.
• Quality and Density Classes: Specifies quality requirements and bar code density classes to optimize readability and data accuracy.
• Label Placement and Size: Recommends best practices for label positioning, sizing, inclusion of free text, and supportive graphics.
• Interoperability: Supports integration with other standards and business processes in inventory management, warehouse operations, and supply chain logistics.

Applications

ISO 22742:2026 is applicable to a broad spectrum of industries utilizing product packaging labels for operational efficiency and supply chain automation. Typical applications include:

• Inventory management: Facilitating accurate tracking of goods, improving stock control, and reducing manual entry errors through bar code scanning.
• Warehouse operations: Enhancing picking, packing, and shipping processes by consolidating key product data into standardized labels.
• Point of purchase: Simplifying product identification and pricing at retail checkout via universally recognized bar codes and 2D symbols.
• Maintenance and logistics: Streamlining traceability, recall management, and compliance by encoding essential information such as serial numbers, lot numbers, and country of origin.
• Supply chain integration: Enabling smooth data exchange between suppliers, manufacturers, and distributors, especially in multi-industry contexts.

The standard is designed to be flexible and is intended for use wherever standardized product labelling supports business, operational, or regulatory needs. It does not override safety or mandatory regulatory requirements but ensures labels support diverse industry practices and traceability demands.

Related Standards

ISO 22742:2026 references and complements several other standards, including:

• ISO 15394: Distribution and transportation processes, for shipment tracking and tracing.
• ISO 28219: Direct part marking requirements.
• ISO/IEC 15415 & 15416: Bar code symbol print quality for 2D and linear codes.
• ISO/IEC 15418 & ANSI MH10.8.2: Data identifiers and GS1 application identifiers.
• ISO/IEC 16022, 18004, 15438: Specifications for Data Matrix, QR Code, and PDF417 symbologies.
• GS1 General Specifications: Global data alignment in retail and supply chain environments.

By aligning with these standards, ISO 22742:2026 provides a comprehensive framework for packaging bar code and 2D symbols, optimizing efficiency in product identification, traceability, and supply chain management.
