The Code 39 - Full ASCII symbology is an extension of the original Code 39 (Code 39 - Regular) symbology that enables encoding of all 128 ASCII characters. Variations of Code 39 have been used extensively in multiple industries, notably in the US military as a component of the Logistics Applications of Automated Marking and Reading Symbols (LOGMARS) system. It was the first barcode symbology to use alphabetic characters in addition to numeric digits.
