ISO/IEC 15459-6:2014规定了用于识别产品、产品包装、运输单位和物品分组的唯一字符串。该字符串旨在以线性条形码符号和二维符号或其他自动识别和数据捕获（AIDC）媒体的形式表示，以满足实体的管理需求和/或监管需求（如清关）。为了满足这些需求，在ISO/IEC 15459的不同部分中识别了不同类型的标识符，这使得在ISO/IEC 15459的特定部分中关联的唯一标识符能够满足不同的要求。 产品、产品包装、运输单位和物品分组的唯一标识符可以按类型、特征、订单、制造、质量、位置、移动等进行分组。 被唯一识别。可以与ISO/IEC 15459其他部分中定义的其他唯一个人标识符一起使用。在数据载体中对这些唯一标识符进行编码，可以清楚地识别有关项目处理的信息。

ISO/IEC 15459-6:2014 specifies a unique string of characters for the identification of groupings of products, product packages, transport units and items. The character string is intended to be represented in a linear bar code symbol and two-dimensional symbol or other automatic identification and data capture (AIDC) media attached to the entity to meet management needs and/or regulatory needs (e.g. customs clearance). To address these needs, different types of identifiers are recognized in the various parts of ISO/IEC 15459, which allows different requirements to be met by the unique identifiers associated within the context of the specific parts of ISO/IEC 15459. The unique identifiers for grouping of products, product packages, transport units and items enables grouping by type, characteristics, order, manufacturing, quality, location, movement, etc. to be uniquely identified. It is possible to use with other unique individual identifiers defined in other parts of ISO/IEC 15459. Encoding these unique identifiers in a data carrier enables information about the item processing to be clearly identified.
