The postal code symbology lies somewhere in between a 2-D and 1-D linear barcode. Instead of encoding the data in the black bar and white space widths, postal codes primarily use the height of the bars. The majority of postal codes only use numbers, but some are now starting to include letters as well.
Barcode technologies provide fast reliable data collection to ensure part or product traceability, error-proof assembly processes, and enhance customer service.
