集装箱是跨境物流过程中的关键运输载体，按有关标准，集装箱标记可分为必备标记和自选标记两类。由于“必备标记”是集装箱都需要标记的内容，具体来说，济南集装箱上有箱主代号；箱号或顺序号、核对号；集装箱尺寸及类型代号。

Containers are key transportation carriers in cross-border logistics processes. According to relevant standards, container markings can be divided into two categories: mandatory markings and optional markings. Due to the fact that "essential markings" are required for all containers, specifically, there is a container master code on Jinan containers; Box number or sequence number, verification number; Container size and type code.

一、必备标记

1、 Mandatory markings

识别标记。它包括箱主代号，设备识别代号、顺序号及核对数字组成。

Identification marks. It consists of the box owner code, equipment identification code, sequence number, and verification number.

（１）箱主代号(OwnerCode)。是集装箱所有人向集装箱局登记注册的三个大写的拉丁文字母表示，比如马士基集团自有箱的箱主代号之一是“MSK”。

(1) The owner code of the container. It is represented by three uppercase Latin letters registered with the International Container Bureau by the container owner, such as "MSK" for one of the container master codes of Maersk Group's own containers.

（２）设备识别代号。是紧接着箱主代号的第四位字母，用以表示集装箱的类型，常见的是“U”，用于表示所有常规的集装箱。另外“J”表示带有可拆卸的集装箱，“Z”表示集装箱的拖车和底盘车。

(2) Equipment identification code. It is the fourth letter immediately following the container master code, used to represent the type of container, commonly known as "U", used to represent all conventional containers. In addition, "J" represents a detachable container, and "Z" represents the trailer and chassis of the container.

（３）顺序号，又称“箱号”或“箱体注册码”（RegistrationCode），由6位阿拉伯字母组成。如有效数字不是6位时，则在有效数字前用“0”补足6位以区别于同一箱主的集装箱，如“053842”。

(3) The sequence number, also known as "case number" or "Registration Code", consists of six Arabic alphabet. If the Significant figures is not 6 digits, use "0" to supplement 6 digits before the Significant figures to distinguish it from the container of the same container owner, such as "053842".

（４）核对数字。又称“校验码”（CheckDigit），核对数字是用来验证箱主代号和顺序号记录是否准确的依据，经计算机处理所得。它位于顺序号后，以一位阿拉伯数字加一方框表示。

(4) Check the numbers. Also known as "Check digit", the check number is used to verify whether the box master code and sequence number records are accurate, and is processed by the computer. It is located after the sequence number and is represented by a Arabic numerals and a box.

三、通行标记

3、 Traffic signs
