UPCE is a variation
of the UPCA symbol that is used for number system 0. By suppressing zeroes, UPCE codes
can be printed in a very small space and are used for labeling small items.
In addition to the requirement that the first digit of the barcode (number system) must
be zero, there are four rules that determine what UPC codes can be printed using the
compressed UPCE format:
 If the last 3 digits of the manufacturer's number are 000, 100, or 200, the valid
product code numbers are 00000  00999 (1,000 numbers).
 If the last 3 digits of the manufacturer's number are 300, 400, 500, 600, 700, 800, or
900, the valid product code numbers are 00000  00099 (100 numbers).
 If the last 2 digits in the manufacturer's number are 10, 20, 30, 40, 50, 60, 70, 80, or
90, the valid product code numbers are 00000  00009 (10 numbers).
 If the manufacturer's number does not end in zero, the valid product code numbers are
00005  00009 (5 numbers).
