1. Barcode Introduction
UPC-E is a variation of UPC-A which allows for a more compact barcode by eliminating "extra" zeros.
Since the resulting UPC-E barcode is about half the size as an UPC-A barcode, UPC-E is generally used on products with very small packaging where a full UPC-A barcode couldn't reasonably fit.
A UPC-E barcode represents 6 digits with an implied number system 0. However, a Number System 1 can be used as well.

Sample of a UPC-E Barcode with Data property = "123450", and UPCENumberSystem = 0.
The data displayed by UPC-E barcode image has the following structure:
Add-On or Supplement code
The Add-On Symbols were designed to encode information supplementary to that in the main bar code symbol on periodicals and paperback books. The Add-On can be composed of 2 or 5 digits only.
