• Barcode 3 of 9 – Barcode 39 symbology is very flexible as you can use
many different code bases for counting. Base 32 is a common base select-
ed for Code 39 multi-bit functions. Using base 32 as an example, within one
character (byte), you can count up to 32 numbers (0, 1, 2, 3, ...31) before
repeating. When you add another charcter for counting, you are multiplying
by 32 the number you can count up, since it is in base 32 format. Conse-
quently, two characters allow counting up to 32 x 32, or 1024 numbers (0, 1,
2, 3...1023) before repeating.
