What is a Data Identifier (DI)?

A Data Identifier is a specified character or string of characters that defines the general category or intended use of the data that follows. DIs are used in automatic identification and data capture (AIDC), IoT, Blockchain, and similar applications. DIs consist of a capital letter (A through Z), optionally preceded by one to three digits (0 through 9).

How are Data Identifiers categorized?

Data Identifiers are organized into 26 categories: Reserved, Container Information, Field Continuation, Date, Environmental Factors, Looping, Human Resources, License Plate, Transaction Reference, Location Reference, Maintenance Codes, Industry-Assigned Codes, Item Information, Measurement, Miscellaneous, Traceability Number for an Entity, Traceability Number for Groups of Entities, UPU/MH10/SC8 Agreed-Upon Codes, Party to the Transaction, Activity Reference, Internal Applications, and Mutually Defined.

How do I request a new Data Identifier?

Submit a DI request application to the Data Identifier Maintenance Committee (DIMC) at direquests@mhi.org. Refer to Annex C of ANSI MH10.8.2 for the request form. The current version of the standard is available at mhi.org/standards/di.

ANSI MH10.8.2 Data Identifiers

ANSI MH10.8.2-2021 | Updated September 9, 2025

This page provides the complete list of Data Identifiers (DIs) defined in ANSI MH10.8.2, the international standard for automatic identification and data capture (AIDC) in supply chain and material handling. A DI is a specified character or string of characters that defines the general category or intended use of the data that follows. DIs are used in barcode, RFID, Internet of Things (IoT), and blockchain applications. This standard is maintained by MHI through the MH10 Committee for Unit Loads and Transport Packages. For authoritative reference, consult the complete ANSI MH10.8.2 standard. To request a new Data Identifier, contact direquests@mhi.org.

The metadata change was necessary because UN/EDIFACT Code Qualifier 2005 lists single-digit qualifiers, and the previous metadata definition did not allow their use. The previous metadata construction was based on the examples provided by the applicant, and not the complete list available.
For a license plate number to be unique world-wide requires: 1) A unique number assigned by the trading partner, 2) A unique code assigned to the trading partner by an organization, and 3) A unique code providing global identification of the assigning organization. ISO/IEC 15459-1 describes the format and usage of these DIs.
The format of "7J" is such that while a Vehicle Registration License Plate Number may, in practice, be unique within a governmental subdivision, it may not be unique worldwide without having met the requirements of items 2 and 3 of footnote 1, above.
"20K" license identifiers, "26S" equipment identifiers and, subject to certain conditions, "18V" party identifiers can be used as the root component of "26T" batch identifiers and of ISO/IEC 15459 transport unit identifiers. To ensure uniqueness of the latter, it is essential that such identifiers differ not only from all other identifiers of the same class, but also from all other identifiers of other classes. That is, the specifications of the issuing agency concerned are required to ensure that a "20K" license identifier is distinct both from other "20K" license identifiers and from "26S" equipment identifiers, "18V" party identifiers, license plates, etc. Since component-based transport unit identifiers are constructed by simple concatenation, it is also required that one root component cannot be derived from another by adding characters to it.
One degree is equivalent to approximately 110,000 meters, depending upon one's location on the earth where, because of its spheroid shape, a degree is of greater distance at the equator than at the poles. Degrees can be reduced to minutes (1/60^th of a degree) and then seconds (1/60^th of a minute) to where a second of latitude or longitude is approximately 30.56 meters. Likewise, we can decimally represent a portion of a meter where to six significant digits one can get to a resolution of 0.11 meters. Secondly, many representations of latitude and longitude include either a North / South designation for latitude, and an East / West designation for longitude. Alternately, some designations of South latitude and West longitude are differentiated from their North and East counterparts by a "-" (minus) prefix. Further, there are 360 degrees of longitude from 180° E to 180° W (alternately 180° to -180°) and 180 degrees of latitude from 90° N to 90° S (alternately, 90° to -90°). Also, the tallest building in 2020 is 828 meters, though plans do exist for structures greater than 1 000 meters in height. Finally, there are locations that exist below sea level, so a minus (-) is additionally required for altitude.

Consequently, the format recommended by this standard for Latitude / Longitude / Altitude is xnn.nnnnn/xnnn.nnnnnn/xnnnn is in a range of 5 (intersection of the Prime Meridian with the Equator - n/n/n) to 27 characters (xnn.nnnnn/xnnn.nnnnnn/xnnnn). The "x" value is to permit the inclusion of a "-" (minus) prefix for South latitudes and West longitudes. The "-" (minus) prefix, "." (decimal point), and "/" solidus are explicitly encoded.
For Freight Containers, this refers to a mechanical seal. See ISO 17712.
For the purposes of DI 18S, the characters dash "-" and slash "/" are part of the allowable character set.
Note that the dash character cannot occur in either of the two components and can thus be used to support decomposition of the batch identifier into these components. A transport unit identifier constructed from the same two components and a "27S" item number contains no such separator and cannot be decomposed.

Frequently Asked Questions

What is a Data Identifier (DI)?: A Data Identifier is a specified character or string of characters that defines the general category or intended use of the data that follows. DIs are used in automatic identification and data capture (AIDC), IoT, Blockchain, and similar applications. DIs consist of a capital letter (A through Z), optionally preceded by one to three digits (0 through 9).
How are Data Identifiers categorized?: Data Identifiers are organized into 26 categories covering container information, dates, environmental factors, item information, measurements, traceability, location references, party identification, activity references, and more. Each category maps to a letter of the alphabet (e.g., Category 2 maps to B, Category 4 maps to D).
How do I request a new Data Identifier?: Submit a DI request application to the Data Identifier Maintenance Committee (DIMC) at direquests@mhi.org. Refer to Annex C of ANSI MH10.8.2 for the request form. The current version of the standard is available at mhi.org/standards/di.
