The Code 39 Extended barcode symbology is also known as Code 39 Full ASCII, etc. It is an extended version of Code 39 that supports all 128 ASCII characters. So with Code 39 Extended you can also code the 26 lower letters (a-z) and other special characters. The additional characters (e.g. lower case letters) are created using the existing characters of Code 39 by combining two characters each.
