Field of Application

In conjunction with the main barcodes EAN and UPC you can use add-on barcodes with 2 and 5 digits. The 2-digit code is often used for the issue number of magazines. The 5-digit code is often used as quotation of prices for books in conjunction with the ISBN barcode (the ISBN-barcode is an application of the EAN-13).

 

Charset / Number of Characters

The charset for both barcodes is limited to the digits 0..9. The number of digits is fixed:

EAN-2: 2 digits

EAN-5: 5 digits

 

Checkdigit

The add-on codes EAN-2  and EAN-5 have no checkdigit.

 

Characteristics

•Between the EAN main barcode and the add-on code a quiet zone of at least the tenfold of a module width is required.

•It is possible to generate with the barcode library add-on codes without a main code, but barcode scanners can not process standalone add-on codes.
