Updated: February 11, 2021

This document provides a comprehensive dictionary of data identifiers (DIs), and provides for the assignment of new DIs, when required.


A DI is a specified character or string of characters that defines the general category or intended use of the data that follows. DIs can be used in automatic identification and data capture (AIDC), Internet of Things (IoT), Blockchain, or other similar applications. DIs described in this document consist of a capital letter (A through Z), optionally preceded by one-, two-, or three digits (0 through 9). DIs are succeeded by a string of letters, numbers, and/or symbols of a length and composition that can vary from DI to DI, which encode specific information pertinent to the item being encoded.
