ISO 17262:2012定义了通用编号和数据结构，用于明确标识用于联运货物运输的设备。这些数据被称为“多式联运货物运输编号和数据结构”。 它独立于数据载体定义数据。数据建模基于ISO/IEC 8824中定义的抽象语法符号1（ASN.1）。它不包括任何物理方面，如接口、尺寸等。不包括构成传输或存储协议（报头、帧标记和校验和）一部分的数据。 ISO 17262:2012中定义的数据需要一个独立于不同AVI/AEI系统的数列控制和分配系统。这是为了避免歧义，并在适当情况下提供必要的安全级别。 因此，ISO 14816中定义的注册机构适用于ISO 17262:2012。 ISO 17262:2012允许使用优化的编码方案，如ASN。1压缩编码规则（PER）。

ISO 17262:2012 defines generic numbering and data structures for unambiguous identification of equipment used for Intermodal goods transport. These data are known as "Intermodal Goods Transport Numbering and Data Structures". It defines data independently of the data carrier. The modelling of data is based on Abstract Syntax Notation One (ASN.1) as defined in ISO/IEC 8824. It excludes any physical aspects such as interfaces, dimensions, etc. Data that form part of transmission or storage protocols (headers, frame markers and checksums) are excluded. Data defined in ISO 17262:2012 require a system for control and distribution of number series independent of the different AVI/AEI systems. This is required in order to avoid ambiguity and to provide the necessary level of security where appropriate. For this reason the registration authority defined in ISO 14816 applies for ISO 17262:2012. ISO 17262:2012 enables the use of optimised encoding schemes such as ASN.1 Packed Encoding Rules (PER).
