Date December 8, 2010 Author AM Labels

The Code 39 Barcode is a alpha numeric symbology that encodes 43 characters (Originally 39, hence the name) consisting of uppercase letters (A – Z), numeric digits (0 – 9) and a few special characters.

The code 39 barcode does not require a check digit as it is considered self-checking because a single print defect cannot transpose one character into another valid character. However, in applications that require an extremely high level of accuracy a checksum digit may be added.

The Code 39 Barcode is suitable for use most industrial and non-retail applications. Although a drawback of the Code 39 is its low data density making it unsuitable for small space applications.
