Don't know that you can find the manufacturer via the barcode.
A google search returns this generic information.
Using the bar code scanner on my smartphone to look up the barcode
from that website turns up even less information.
You can. The first six digits are the manufacturer's specific code, called
the "Company Prefix". All but one of the rest of the numbers are for the
company's use for product identification. The last number is a check digit,
which validates the rest of the number.
I'm not sure how correct that page is.
From GS1 Canada's page
"Your Company Prefix Licence is a globally-unique number that accurately
identifies your company. Use it to create the numbers that go inside the
GS1 bar codes on your products."
I deal with this sort of thing from time to time, and I have not yet come
across any conflicts between Company Prefixes. Each UPC definitively
resolves to a specific company that is still in existence. That company may
not be the original holder of a specific UPC, but it will be the company
that currently markets the product with that UPC.
It's not really that easy to find out this stuff. You need to be a member
of GS1, the organization that issues all UPCs. Fortunately for you, I'm one
of those members.
The numbers "772677" tell me what I need to know.
Your sheetrock was marketed by CertainTeed Gypsum Canada, Inc.. They are in
a city called Mississauga, which is just west of Toronto, Ontario.
The phone number listed for CertainTeed is 905-823-9881.
I cannot tell from the UPC whether or not the board was /made/ in Canada.
For that you need to see the information printed on the product itself.
Please take careful note that the company listed on the UPC is the one that
sold the product directly to the retailer. Identification of the actual
/manufacturer/ of the product is /not/ part of the UPC standard.
The actual manufacturer(s) may or may not be several times removed from the
company that sold the product to the retailer, and there exist absolutely
no records of any kind which would follow that, outside of internal company
Also please take careful note that it's not a sure thing that CertainTeed
will assume responsibility for the product or its performance post-sale.
They may insist that you go through their retail-selling partner (the place
you bought it from) for any assistance, which is part of the retailer's
The upshot: Don't be surprised if you get stonewalled by CertainTeed;
you're not really supposed to be calling them.
Siince the UPC code isn't governed by any governmental agency, users may
create the code in any way they wish in order to match it to their already
existing database system/s. It's only really used for inventory control,
notifying buyers of items needing to be ordered, sometimes even does the
ordering, and the retail price at the store, sometimes with a promotional,
lower price also.
There isn't even a consistant length to a UPC code except for the bar
code reader that will scan it may have limits.
There ARE mil-specs for such things but nothing forces a non-military
company to use them unless it's a product FOR and specced by the military.
Same with FBI, FTC, ATF, Etc. etc. etc..
