Code 93 Barcode Generating Tool

This online tool generates a 1-dimensional barcode symbol (Code 93) representing variable length text messages.

Code 93 is an extension of the Code 39 barcode that includes error control and a full set of 128 ASCII characters. The barcode is based on a limited set of 43 printable characters as shown below plus four control characters (43,44,45,46) to give 47 total characters. Code 93 encodes other 7-bit ASCII characters in two symbols using one of the control characters as a prefix (e.g. 'z' = '[46]Z')

0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z - . spc $ / + %

This tool encodes extended Code 93 symbols only for lowercase text; all other characters not found above are ignored.
