Code 39 extended

Barcode-Glossary

Code 39 extended

With the extended Code 39 (VBCD: Code 39 extended), the complete ASCII-character set can be displayed. The 128 characters according to ISO 646 are displayed by combining two symbol characters, the first one consists of one of the four characters $ + % / and is followed by one of the 26 letters. If the decoder is programmed with the complete ASCII-character set, only the ASCII-equivalent is transferred and not the symbol character combination.

Symbol Example

Code 39 extended

Because of the fact that using the Code 39 extended prerequisites a special programming of the decoders, a general utilization should be refrained from. Other symbologies (e.g. "Code 128", "Code93 extended") are equipped with the ASCII-character range as a standard feature.
