FAQ of the moment:
What is this bar code? It looks like UPC, but has too few characters.
UPCE, also called zero suppressed UPC was designed to be used by manufacturers to label small products. You'll see UPCE on gum, candy, and other small items.
Details
This web page has a nice discussion of UPCE, but in case of it's disapperance, the zero compression rules are:
If the manufacturer code ends in 000, 100, or 200, the UPC-E code consists of the first two characters of the manufacturer code, the last three characters of the product code, followed by the third character of the manufacturer code. The product code must be 00000 to 00999.
If the manufacturer code ends in 00 but does not qualify for #1 above, the UPC-E code consists of the first three characters of the manufacturer code, the last two characters of the product code, followed by the digit "3". The product code must be 00000 to 00099.
If the manufacturer code ends in 0 but does not quality for #1 or #2 above, the UPC-E code consists of the first four characters of the manufacturer code, the last character of the product code, followed by the digit "4". The product code must be 00000 to 00009.
If the manufacturer code does not end in zero, the UPC-E code consists of the entire manufacturer code and the last digit of the product code. Note that the last digit of the product code must be in the range of 5 through 9. The product code must be 00005 to 00009.
