Global Location Number: GS1 Identification Key, using the GTIN-13 data structure to identify physical locations or legal entities.

Global Trade Item Numbers® (GTINs®). GTIN may use the data structure for GTIN-8, GTIN-12, GTIN-13 or GTIN-14 and must be represented in a 14-digit reference field (key) in computer files to ensure uniqueness of the identification numbers.

The conduct of business communications and management through electronic methods, such as Electronic Data Interchange (EDI) and automated data collection systems.

A composition of Element Strings from scanned data and transaction information assembled for data validation and unambiguous processing in a user application.

A piece of data defined in structure and meaning, comprising an identification part (prefix or Application Identifier) and a data part, represented in a GS1 System endorsed data carrier.

Legacy term, for current naming convention see GTIN-12, GDTI-12, Coupon -12.

A digit from 1 to 9 in the leftmost position of the GTIN-14.

The representation of several Element Strings in one bar code symbol.

An ISO 15416 parameter that measures the difference between the largest and smallest reflectance values in a Scan Reflectance Profile (SRP).

An item of any composition established for transport and/or storage that needs to be managed through the supply chain. It is identified with SSCC.

Measures indicating the outside dimensions, total weight, or volume inclusive of packing material of a logistic unit. Also known as gross-measures.

A member of GS1 that is responsible for administering the GS1 System in its country (or assigned area).

Means that such system data may be applied to goods, to be implemented all around the world, without any restriction as to country, company, industry sector.

A component of the GS1 Company Prefix. GS1 Member Organisations assign GS1 Company Prefixes to entities that administer the allocation of GS1 System identification numbers. These entities may be, for example, commercial companies, not for profit organisations.

A means to represent data in a machine readable form; used to enable automatic reading of the Element Strings.

Means that such system data may be applied to goods, in order to be implemented only in specific environments, defined by GS1, for example country, company, industry sector.

Application Identifier

The field of two or more characters at the beginning of an Element String encoded in the GS1-128 symbol, that uniquely defines its format and meaning.

A special representation of a GS1 Company Prefix constructed from a U.P.C. Prefix and a Company Number. The U.P.C. Company Prefix is only used to create GTIN-12 (UPC-12).

The part of the data structure allocated by the user to identify a trade item for a given GS1 Company Prefix.

A clear space containing no machine-readable marks, which precedes the Start Character of a bar code symbol and follows the Stop Character. Formerly referred to as “Clear Area” or “Light Margin.”

Unique GS1 Identification Key for logistic units, using the 18-digit GS1 System Identification Key comprising an Extension digit, GS1 Company Prefix, Serial Reference, and Check Digit used to identify a logistic unit.

A bar code symbol used to encode information supplementary to that in the main bar code symbol.

The Interleaved 2 of 5 Symbology.

A defined method of representing numeric or alphabetic characters in a bar code; a type of bar code.

An electronic device to read bar code symbols and convert them into electrical signals understandable by a computer device.

Printing a symbol shorter than the symbology specification’s minimum height recommendations. Truncation can make the symbol difficult for an operator to scan.

GS1 data structure, defined in different lengths, necessary for different identification purposes, composed in an even hierarchy. Their composition combines the needs for international control with the users’ needs.

Legacy term, for current naming convention see GS1 US

Any item (product or service) upon which there is a need to retrieve pre-defined information and that may be priced, or ordered, or invoiced at any point in any supply chain.

An item always produced in the same pre-defined version (e.g., type, design, packaging) that may be sold at any point in the supply chain, which either may vary in weight/size by its nature or which may be traded without a pre-defined weight/size/length.

An item always produced in the same pre-defined version (e.g., type, size, weight, contents, design) that may be sold at any point in the supply chain.

Net measures of Variable Measure Trade Items as used for invoicing (billing) the trade item.

Different sizes of bar code symbols based on a nominal size and a fixed aspect ratio; stated as a percent or decimal equivalent of a nominal size.

Term used to describe a data field in an Element String with an established number of characters.

A special representation of the GS1 Prefixes ’00 – 09’ with the leading zero removed.

The specified width of the narrow element in a bar code symbol

A digit, allocated by the user, used to increase the capacity of the Serial Reference within the SSCC (Serial Shipping Container Code).
