Comments
UPC-E is a six-digit UPC symbology.
UPC-E compresses a normal 12-digit UPC-A code into a
six-digit code by "suppressing" the first (number system)
digit, trailing zeros in the manufacturer's code, and leading
zeros in the product identification part of the bar code.
A seventh check digit is encoded into a parity pattern for the
six main digits.
The UPC-E code can only be used if the number system digit
is 0 and the original 10 data characters have at least four
zeros.
UPC-E allows for a supplemental two- or five-digit number to
be appended to the main bar code symbol.
