Code 93 or Code 9 of 3 Bar Codes

The Code 93 bar code is used for applications that require heavy error checking capabilities. To

accomplish this, the Code 93 bar code contains two separate error checking checksums that are

automatically calculated and placed into the bar code. This bar code is used for inventories, hospital

applications, or any other place where the length may change between items being scanned. (See Code

39 above.) This bar code type can use the entire ASCII 128 character set. It is useful for encoding data and

phrases like “Code 93”.

The two checksums in this bar code are located as the last and second to last characters in the decoded

bar code. Code 93 has a complex checksum calculation. Please see the bar code symbology specification

for information on how to create and decode this checksum. Please also note that the bar code symbology

specification does not state any ideal values for the ratio and the width of the narrow bar.
