GS1 应用标识符（AI）
GS1 应用标识符（AI）是一个由两到四位数字组成的前缀，用于告知扫描器其后数据的含义。AI 01 表示 GTIN，10 表示批号，17 表示有效期。只有借助 AI，一个条码才能同时承载多个字段，这正是 GS1-128、GS1 DataMatrix 和 GS1 DataBar 的设计用途。
下表列出了 GS1 定义的所有 AI，以及每个 AI 的官方简称和数据格式。标识符、标题和格式代码属于 GS1 标准，因此以原始表示形式列出，不作翻译。
如何解读数据格式： N 表示数字，X 表示该标准的字母数字字符集。不带点号的数字表示固定长度，因此 N14 表示恰好 14 位数字。两个点表示长度可变且不超过该最大值，因此 X..20 表示最多 20 个字符。加号用于连接复合字段的各部分，方括号表示可选部分。以范围形式书写的标识符（例如 3100-3105）使用其最后一位表示小数位数。
源文本中有两个标识符没有简称，因此其名称列为空。
