Code39, also known as 3 of 9 code, USD-3 and LOGMARS, is a widely used bar code symbology defined in ISO/IEC 16388:2007 standard.
LOGMARS stands for Logistics Applications of Automated Marking and Reading Symbols. It is a variation of code 39 as defined in Military Standard MIL-STD-1189B.
Code 39 only accepts 43 valid input characters:
26 uppercase alphas (A - Z),
10 digits (0 - 9),
hyphen(-), period(.), space, dollar sign($), slash(/), plus(+) and percent (%).
Other input characters will be omitted by the Code39 system.
Code39 is a self-checking barcode symbology that usually does not require a checksum digit. But in applications that require high accuracy, a modulo 43 checksum character is appended after the data. If you download Barcodesoft code39 demo, you will find source code in VBA and C language of Code39 checksum calculation.
