UPC-E Barcode

UPC-E is a variation of the UPC-A symbol that is used for number system 0. It is often used for small retail items.

UPC-E is also called "zero suppressed UPC" because UPC-E compresses a normal 12 digit UPC-A number into a six digit code by "suppressing" the number system digit, trailing zeros in the manufacturers code and leading zeros in the product identification part of the code.
