However, application identifier 10 has two numbers for the application identifier itself and then up to 20 alphanumeric characters. For example, application identifier 01 has a predefined length of 16 characters (two for the application identifier itself and then 14 for the GTIN), and application identifier 17 has a predefined length of eight characters (two for the application identifier itself and then six for the date). All other application identifiers have variable length, and the GS1 application identifier list specifies the maximum length and format of data. There is a fixed list of application identifiers that have predefined lengths. Application identifier 10 – The batch number.įor each element, the data might have either a predefined length or a variable length.Application identifier 17 – The expiration date.Application identifier 01 – The GS1 global trade item number (GTIN) of the item.Usually, the data is also presented under the bar code in a human-readable format, where the application identifier is shown in parenthesis. The data in the bar code itself consists of multiple data elements, each of which is identified by an application identifier at the start of the field. The presence of an FNC1 character indicates that the data in the bar code should be interpreted according to the GS1 specification. The difference between the GS1 version and the non-GS1 version is the presence of a special character (FNC1) as the first character in the bar code data. Note that there are special mentions of GS1 in GS1-128, which is a special case of the ordinary Code-128 linear bar code, GS1 DataMatrix, and GS1 QR Code. 2D bar codes – GS1 DataMatrix, GS1 QR Code, and GS1 Dotcode.Linear or 1D bar codes – GS1-128 and GS1 DataBar.GS1 bar codes use the following symbologies: The GS1 specifications document is regularly updated, and the information that it provides is up to date with GS1 General Specifications release 22.0. For full details, see the GS1 General Specifications that are published by GS1. This section provides a short introduction to the article. The GS1 General Specifications specify which symbologies can be used for GS1 bar codes and how to encode the data in the bar code. Unless otherwise stated, this article uses the term bar code to refer to both linear (1D) bar codes and 2D bar codes. Therefore, all shipping labels will take a unified form. The application identifiers can then be used across warehouses as a global setting for moving and packing purposes. Logistics managers must set up the required list of application identifiers and associate each of them with the appropriate mobile device menu items. At the same time, they also help improve accuracy. By eliminating the need to do multiple scans and/or manually enter information, GS1 bar codes help reduce the time that is associated with tasks. Warehouse workers can extract all the required information through a single scan of a GS1 bar code. GS1 support in Supply Chain Management dramatically simplifies the scanning process in warehouses where pallets and containers are labeled by using bar codes in GS1 format. Therefore, a single bar code scan can capture several types of product information, such as the batch and the expiration date. Unlike older bar code standards, GS1 bar codes can have multiple data elements. The GS1 standard defines the data format and the various kinds of data that it can be used to encode. GS1 bar codes not only encode data but also let you use a predefined list of application identifiers to define the meaning of that data. They are available in both linear (1D) symbologies (bar code formats), such as GS1-128, and 2D symbologies, such as GS1 DataMatrix and GS1 QR codes. GS1 bar codes for shipping labels were developed to provide a global standard for the exchange of data between companies. The bar codes use a company-specific format that you define and manage by using Microsoft Dynamics 365 Supply Chain Management. These tasks can include both scanning bar codes and manually entering information on the mobile device. Warehouse workers often have to complete several tasks when they use a mobile device scanner to register movements of an item, palette, or container.
