However, if you are simply talking about UPC bar codes, then
you need to visit the Uniform Code Council's web site. They
have a scheme where the digits are broken into three sections.
From
http://www.uc-council.org/ean_ucc_system/membership/need_upc.htm
There are three parts that make up your 12-digit GTIN
<javascript:show('definitionBox',56)>.
1. Your UCC Company Prefix <javascript:show('definitionBox',52)>
(number provided by the Uniform
Code Council)
2. Your Item Reference <javascript:show('definitionBox',53)> (number
you assign to identify your
individual products)
3. Check Digit <javascript:show('definitionBox',54)> (validates the
accuracy of the number)
That means that each company is responsible for their own
"subnet" of UPC code space.
So really, what you're looking for is a database of databases,
since UCC keeps a list of Companies and each company keeps a
list of their own product codes (called GTIN's).
