Code 93 & Code 93 Extended

Description of Code 93 & Code 93 Extended

Code 93 & Code 93 ExtendedCode93 and Code93 Extended are barcode symbologies used for encoding alphanumeric and special characters.

Code 93
Code 93 is a linear barcode symbology that allows the representation of uppercase letters, numeric digits, and a set of special characters. It was developed to provide a compact and versatile barcode solution. Code 93 can encode the entire ASCII character set, including alphanumeric characters, punctuation marks, and control characters. It is often used in industries such as logistics, healthcare, and inventory management.

Code93 Extended
Code93 Extended is an extension of the Code 93 barcode symbology. While the regular Code 93 is limited to a specific set of characters, Code 93 Extended expands the character set to include the entire ASCII character set. This means it can encode additional special characters, lowercase letters, and extended ASCII characters. Code 93 Extended provides greater flexibility for encoding a wide range of data, making it suitable for applications that require more extensive character support.

Both Code 93 and Code 93 Extended use a start and stop characters, as well as a checksum digit for error detection. The check digits according to Modulo 47 are not displayed in the plain text line. They can be scanned by barcode readers or scanned using smartphone apps with barcode scanning capabilities.

The characters represented by Code 93 are represented in Code 93 Extended as single barcode characters, but all other characters are represented by a control character plus another character. Take this into account when choosing this barcode type - it needs more space when using characters not covered by Code93.
