For a barcode to work, it is comprised of various codes or symbols. These codes contain both numbers and letters, have variable or fixed length, and most include check digits. We wanted to provide you with a list of some of the common codes you would find in barcode labels. Keep in mind that this is not an all-inclusive list.
- Code 39 (Code 3 of 9) – This particular code is used for purposes of identification, inventory, and tracking. The code itself is variable in length, offers alphanumeric string support, and is printable in ratios of varying aspects and sizes using a coordinating ID printer.
- Code 93 – In this case, the symbols are compact, typically used for various electric components.
