Certain data fields with Application Identifiers make use of an additional check digit, usually a MOD 10. For example, all GS1 DataBar (RSS) symbologies have an implied Application Identifier of '01'.Īutomatic addition of check digits to certain data fields. If a symbology is always used for the same application, then the Application Identifier will appear in the human readable part of the symbol but not the barcode. They tell a barcode reader what type of data field to expect and often the length of the data field as well. In GS1 barcodes, Application Identifiers immediately precede the string of characters that they identify. All of the current GS1 Application Identifiers are supported by BarTender. This use of the FNC1 character is described in more detail in the following topics, GS1 Application Identifiers and Entering Function Characters into the GS1-128 (UCC/EAN-128) Data String. The FNC1 character may be entered manually by putting '^1' into the barcode data string for use as a field separator when combining multiple data fields into a single barcode. It is used as an identification prefix or 'flag character' to indicate that the rest of the symbol code complies with the new GS1 distribution standards.Īdditional FNC1 characters can be entered manually. (If the symbology is GS1-128 (UCC/EAN-128), it appears immediately following the GS1-128 (UCC/EAN-128) start character). A FNC1 character is printed at the beginning of the barcode. Leading FNC1 character generated automatically. When the GS1-128 (UCC/EAN-128) option or the Apply Application Identifier Specification option on the Symbology and Size property page is enabled, BarTender automatically adds certain characters and performs certain functions required to print GS1-128 (UCC/EAN-128) compliant barcodes, including the following:

For example, the AI '01' indicates that what follows is the 14-digit GS1 primary identification number, and AI '30' means that what follows is the number of items in each package. An AI is a numeral that prefixes and identifies the intended purpose (such as batch number or perishability date) of a barcode data field. These new standards, often called 'GS1-128 (UCC/EAN-128),' specify a standard of Application Identifiers (AI). In early 1991 the Uniform Code Council (UCC) and the International Article Numbering Association (EAN) released new barcode standards for use in the worldwide distribution of retail, industrial, and commercial products.
