UPC
There are two principal UPC version:
UPC-A is the basic version of UPC and is usually the version seen
on grocery store items. The symbology is used to encode the ten digit
Universal Product Code. An eleventh digit indicates the type of product,
and a twelfth digit is a modulo check digit.
UPC-E is the next most common version of UPC. It's a zero suppression
version of UPC. It is intended to be used on packaging that would
be otherwise too small to use one of the other versions. The code
is smaller because it drops out zeros that would otherwise occur in
a symbol.
Note: The Uniform Code Council announced Monday, June 9, 1997 that
UPC will be phased out by the year 2005. The reason is that 12 digit
UPC will run out of numbers by then. The United States will finally
adopt EAN (what the rest of the world uses)
which has thirteen digits.
