标准范围

唯一标识可以发生在供应链中的许多不同级别、运输单元、物品级别和其他地方。这种不同的实体通常由几方处理:发送方、接收方、一个或多个承运人、海关当局等。这些各方中的每一方必须能够识别和跟踪物品，以便可以参考相关信息，例如配置、维护历史、地址、订单号、物品内容、重量、发送者、批次或批号等。信息通常保存在计算机系统上，并且可以经由EDI(电子数据交换)和XML(可扩展标记语言)消息在相关方之间交换。如果物品的身份以条形码格式或其他AIDC（自动识别和数据捕获）介质表示，并且附接到被唯一识别的物品或使其成为其组成部分，则存在相当大的益处，以便它可以通过电子方式阅读，从而最大限度地减少错误；一个身份可供各方使用；每一方可以使用该身份查找其计算机文件，以找到与该项目相关联的数据；标识符在类中是唯一的，并且在项目的生存期内不能出现在类的任何其他项目上。在ISO/IEC 15459-4:20 08中定义并在条形码标签、二维符号、射频识别标签或附加到物品的其他AIDC介质中表示的单个物品的唯一标识符满足了这些需求。所有AIDC技术都有可能编码唯一标识符。预期将基于作为主密钥的唯一标识符来开发使用各种自动识别技术的物品的应用标准。这些应用标准可以从发布机构获得。ISO/IEC 15459-4:20 08为单个项目的唯一标识符指定了一个唯一的、非有效的字符串。字符串旨在表示在附接到物品的条形码标签或其他AIDC介质中，以满足供应链需求。为了解决管理需求，在ISO/IEC 15459的各个部分中识别不同类别的项目，这允许通过与每个类别相关联的唯一标识符来满足不同的要求。为单个项目定义规则以识别项目的唯一出现，理解为意味着将在两个未来国际标准（分别为ISO 17367和ISO 17366）中定义的层零和层一。

Unique identification can occur at many different levels in the supply chain, at the transport unit, at the item level, and elsewhere. Such distinct entities are often handled by several parties: the sender, the receiver, one or more carriers, customs authorities, etc. Each of these parties must be able to identify and trace the item so that reference can be made to associated information such as configuration, maintenance history, address, order number, contents of the item, weight, sender, batch or lot number, etc.The information is often held on computer systems, and may be exchanged between parties involved via EDI (Electronic Data Interchange) and XML (eXtensible Markup Language) messages.There are considerable benefits if the identity of the item is represented in bar code format, or other AIDC (Automatic Identification and Data Capture) media and attached to or made a constituent part of that which is being uniquely identified so that

• it can be read electronically, thus minimising errors;
• one identity can be used by all parties;
• each party can use the identity to look up its computer files to find the data associated with the item;
• the identifier is unique within the class and cannot appear on any other item of the class during the lifetime of the item.

The unique identifier for individual items defined in ISO/IEC 15459-4:2008 and represented in a bar code label, two-dimensional symbol, radio-frequency identification tag, or other AIDC media attached to the item meets these needs.All AIDC technologies have the potential to encode a unique identifier. It is expected that application standards for items, using various automatic identification technologies, will be developed based upon the unique identifier as a prime key. These application standards may be made available from the Issuing Agency.ISO/IEC 15459-4:2008 specifies a unique, non-significant string of characters for the unique identifier for individual items. The character string is intended to be represented in a bar code label or other AIDC media attached to the item to meet supply chain needs. To address management needs, different classes of items are recognized in the various parts of ISO/IEC 15459, which allows different requirements to be met by the unique identifiers associated with each class. The rules are defined for the individual items to identify the unique occurrence of an item, understood to mean the layers zero and one as will be defined in two future International Standards (ISO 17367 and ISO 17366, respectively).
