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).
