Search 100 million UPC, EAN, ISBN, ASIN and MPN identifiers (productids.org)

Doesn't work on "house brands" that use internal number schemes. For example 150480300036 is the UPC-A bar code from a Banana Republic T-shirt with a product id of 637905 but it doesn't exist in their database. Anyone know of somebody trying to deal with these kind of bar code issues?

I tried 6 products I had at hand, no match for any of them...

It doesn't seem to contain recent information: I checked the ISBNs from the latest books of a few publishing houses and none of them seems to be recognized :(.

I tried a box of Kleenx that's sitting on my desk and that worked, so there is something in there.
