Freight containers - Coding, identification and marking (ISO 6346:2022, Corrected version 2022-08)
This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves.
The methods of displaying identification and certain other data (including operational data) on containers by means of permanent marks are included.
This document specifies:
a) a container identification system, with an associated system for verifying the accuracy of its use, having:
— mandatory marks for the presentation of the identification system for visual interpretation, and
— features to be used in optional Automatic Equipment Identification (AEI) and electronic data interchange (EDI);
b) a coding system for data on container size and type, with corresponding marks for their display;
c) operational marks, both mandatory and optional;
d) physical presentation of marks on the container.
The terms “mandatory” and “optional” in this document are used to differentiate those ISO marking provisions which shall necessarily be fulfilled by all containers from those which are not required of all containers. The optional marks are included to further comprehension and promote uniform application of the optional mark. If a choice has been made to display an optional mark, the provisions laid down in this document relating to the mark shall be applied. The terms “mandatory” and “optional” do not refer to requirements of any regulatory body.
This document applies to all freight containers covered by International Standards ISO 668, parts 1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied:
— to containers other than those covered by the International Standards mentioned in Clause 2;
— to container-related and/or detachable equipment.
NOTE 1 Containers marked according to previous editions of ISO 6346 need not be re-marked.
This document does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or nongovernmental organizations.
NOTE 2 Some of the major international conventions whose container-marking requirements are not covered in this document are as follows:
— International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization (IMO);
— Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under customs seal.
— Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission.
It should not be assumed that this list is exhaustive.
This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor does it, in any way, include identification marks or safety signs for items of cargo which may be carried in freight containers.

Conteneurs pour le transport de marchandises - Codage, identification et marquage (ISO 6346:2022, Version corrigée 2022-08)
Le présent document fournit un système pour l’identification et la présentation d’informations relatives aux conteneurs pour le transport de marchandises. Le système d’identification est prévu pour une application générale (par exemple, pour la documentation, le contrôle et les communications, y compris les systèmes de traitement automatique des données) ainsi que pour le marquage sur les conteneurs eux-mêmes.
Les méthodes d’inscription de l’identification et de certaines autres informations (y compris les données opérationnelles) sur les conteneurs, au moyen de marques permanentes, sont incluses.
Le présent document spécifie:
a) un système d’identification des conteneurs incluant un dispositif pour vérifier l’exactitude de son utilisation, avec:
— des marques obligatoires pour la présentation du système d’identification aux fins d’interprétation visuelle, et
— des éléments à utiliser pour l’identification (facultative) automatique des équipements (AEI) et l’échange électronique de données (EDI);
b) un système de codage des données relatives aux dimensions et au type de conteneur, et les marques correspondantes à inscrire;
c) des marques, obligatoires et facultatives, relatives à l’exploitation;
d) une présentation physique des marques sur le conteneur.
Dans le présent document, les termes «obligatoires» et «facultatifs» sont utilisés pour différencier les dispositions relatives au marquage ISO, qui doivent nécessairement être respectées pour tous les conteneurs, des dispositions qui ne sont pas exigées pour tous les conteneurs. Les marques facultatives sont incluses pour faciliter la compréhension et encourager une application uniforme de ces marques. S’il a été décidé d’inscrire une marque facultative, les dispositions spécifiées dans le présent document relatives à cette marque s’appliquent. Les termes «obligatoire» et «facultatif» ne font pas référence aux exigences d’organismes de réglementation.
Le présent document s’applique à tous les conteneurs pour le transport de marchandises couverts par les Normes internationales ISO 668, ISO 1496 (Parties 1 à 5) et ISO 8323. À chaque fois que cela est approprié et possible, il convient qu’il s’applique:
— aux conteneurs autres que ceux couverts par les Normes internationales mentionnées à l’Article 2;
— aux équipements de conteneurs et/ou aux équipements amovibles.
NOTE 1 Il n’est pas nécessaire de marquer à nouveau les conteneurs déjà marqués conformément aux éditions précédentes de l’ISO 6346.
Le présent document ne couvre pas les marques temporaires relatives à l’exploitation (quel que soit leur type), les marques permanentes, les plaques d’identification, etc., qui peuvent être requises par des accords intergouvernementaux, par la législation nationale ou par des organisations non gouvernementales.
NOTE 2 Certaines des principales conventions internationales dont les exigences de marquage des conteneurs ne sont pas couvertes par le présent document sont indiquées ci-après:
— Convention internationale sur la sécurité des conteneurs (1972, telle qu’amendée) (CSC), Organisation maritime internationale (OMI);
— Convention douanière relative aux conteneurs (1956 et 1972), relative aux admissions temporaires et au transport sous scellement douanier;
— Convention relative à l’admission temporaire (Istanbul, 26 juin 1990), relative aux admissions temporaires.
Il convient de ne pas considérer cette liste comme exhaustive.

– Mednarodna konvencija o varnosti zabojnikov (CSC) (iz leta 1972, kot je bila spremenjena), Mednarodna pomorska organizacija (IMO);
– Carinska konvencija o zabojnikih iz leta 1956 in leta 1972 v zvezi z začasnim uvozom in prevozom pod carinsko oznako;
– Konvencija o začasnem uvozu (Istanbul, 26. junij 1990) v zvezi z začasnim uvozom.
Ta seznam se naj ne obravnava kot izčrpen.
Ta dokument ne obravnava prikaza tehničnih podatkov na cisternah-zabojnikih (glej standard ISO 1496-3), niti ne vključuje identifikacijskih oznak ali varnostnih znakov za kose tovora, ki jih lahko vsebujejo tovorni zabojniki.
General Information
Relations
Overview
EN ISO 6346:2022 (ISO 6346:2022, Corrected version 2022-08) is the international/CEN standard for the coding, identification and marking of freight containers. It defines a uniform system for uniquely identifying containers and for presenting key container information both in documentation and as permanent marks on the container body. The standard supports visual interpretation, automatic equipment identification (AEI) and electronic data interchange (EDI) while distinguishing mandatory and optional marking provisions.
Key topics and technical requirements
- Container identification system
- Owner code, equipment category identifier, serial number and check digit for verification.
- Provisions that support AEI and EDI implementations.
- Size and type coding
- Standardized two-character size and two-character type codes with corresponding visible marks.
- Operational marks
- Mandatory marks (e.g., maximum gross mass, tare mass, air/surface symbol, warnings for overhead electrical danger).
- Optional marks (e.g., maximum payload) - if used, must follow the standard’s requirements.
- Physical display of marks
- Rules for layout, location, size and colour of markings on the container.
- Specific provisions for taller or wider containers (height marks for containers higher than 2.6 m / 8 ft 6 in; width marks for containers wider than 2 438 mm / 8 ft).
- Normative annexes
- Detailed methods such as determination of the check digit, symbol specifications (air/surface and overhead electrical danger), and size/type code tables.
Practical applications and users
- Who uses it:
- Container owners and leasing companies for consistent fleet identification.
- Shipping lines, intermodal terminals and freight forwarders for tracking, handling and documentation.
- Customs, ports and regulatory bodies for inspection and recordkeeping.
- Logistics software developers (TMS/WMS, EDI/AEI integrators) to ensure interoperability of automated systems.
- Container manufacturers and repairers for correct application of permanent marks.
- Key benefits:
- Enables reliable manual and automated identification across international supply chains.
- Improves data accuracy via the check digit and standard coding (size/type), reducing handling errors.
- Facilitates AEI/EDI integration for faster, interoperable operations and compliance with interoperable documentation.
Related standards
- ISO 668 (container classification and dimensions)
- ISO 1496 (container specifications, parts 1–5 and tank container ISO 1496-3 is excluded from some markings)
- ISO 8323 (related container types)
- Note: EN ISO 6346 does not replace national or international regulatory marking requirements (e.g., CSC, customs conventions); containers marked to previous editions need not be re-marked.
For compliance and implementation, reference the full EN ISO 6346:2022 text (Corrected version 2022-08) and consult your national standards body or CEN member for adoption details.

Freight containers — Coding, identification and marking
1 Scope
1.1 This document provides a system for the identification and presentation of information about
freight containers. The identification system is intended for general application, for example in
documentation, control and communications (including automatic data processing systems), as well as
for display on the containers themselves.
The methods of displaying identification and certain other data (including operational data) on
containers by means of permanent marks are included.
1.2 This document specifies:
a) a container identification system, with an associated system for verifying the accuracy of its use,
having:
— mandatory marks for the presentation of the identification system for visual interpretation,
and
— features to be used in optional Automatic Equipment Identification (AEI) and electronic data
interchange (EDI);
b) a coding system for data on container size and type, with corresponding marks for their display;
c) operational marks, both mandatory and optional;
d) physical presentation of marks on the container.
1.3 The terms “mandatory” and “optional” in this document are used to differentiate those ISO
marking provisions which shall necessarily be fulfilled by all containers from those which are not
required of all containers. The optional marks are included to further comprehension and promote
uniform application of the optional mark. If a choice has been made to display an optional mark, the
provisions laid down in this document relating to the mark shall be applied. The terms “mandatory”
and “optional” do not refer to requirements of any regulatory body.
1.4 This document applies to all freight containers covered by International Standards ISO 668, parts
1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied:

La norme EN ISO 6346:2022 fournit un cadre rigoureux pour le codage, l'identification et le marquage des conteneurs de fret. Son champ d'application est essentiel pour assurer une identification claire et précise, facilitant ainsi la documentation, le contrôle et la communication concernant les conteneurs de fret. Cette norme est pertinente pour toutes les parties concernées dans la logistique, le transport maritime et la gestion des conteneurs, car elle établit des méthodes uniformes pour l'affichage des informations sur les conteneurs eux-mêmes grâce à des marques permanentes. Parmi les points forts de cette norme, on note la création d'un système d'identification des conteneurs, qui inclut des marques obligatoires pour l'interprétation visuelle ainsi que des fonctionnalités pour l'identification automatique des équipements (AEI) et l'échange de données électroniques (EDI). Cela renforce non seulement l'efficacité opérationnelle, mais assure également la cohérence sur le plan international. L'inclusion de systèmes de codage pour la taille et le type de conteneurs, ainsi que des marques opérationnelles, témoigne de la profondeur et de la robustesse de cette norme. Un autre aspect important est la distinction entre les marques obligatoires et facultatives, ce qui facilite la compréhension des exigences de marquage pour les utilisateurs. Les dispositions de cette norme permettent aux parties prenantes de choisir d'appliquer des marques facultatives tout en fournissant des directives claires à suivre.
