Some time ago a poster asked who made the drywall he's bought. I went onto
GS1 and found out who it was. At the time I thought you needed to be logged
in to get access to the database, but it turns out that may not be totally
Go go GS1, the organization that controls all UPC codes.
Click on the link at bottom left: "Who owns this barcode?"
The first postings were back Feb 15, 2012
The code as it appears on the gypsum drywall:
7 72677 00248 8
From memory, manufactured in North Carolina
You had recommended the GS1 website earlier, but the information for
manufacturer was circular, back to GS1
The product came up correctly, well in a way.
I still don't know who made this drywall.
Well, if in NC odds are it was National Gypsum, then.
Of course, it well may be actually been manufactured in another of their
locations and the barcode simply refers to home office state; that's the
call of how the company uses/codes their info afaik.
It's telling you you need to go to GS1 Canada to get the information you
want. And, unfortunately, it appears the Canadian site does not have a
public-access search for GLN ownership. I think you'd have to actually
Way back in February I posted who made it. It was made by CertainTeed
Gypsum, in Canada. I know this because I have a login on the Canadian GS1
CertainTeed's GLN is 772677.
It looks like the US site's search only works for US-made products.
Thanks, missed that somehow. Worse it took 1/2 hour to find those old
postings! Did you post the contact information, too?
Anyway, the joint compound from Walmart is Proforma, made by National
Gypsum and definitely out of North Carolina and definitely the wrong
UPC code. something like 0222????
This is part of what I posted on Feb 15th:
"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."
You need the whole GTIN be able to find the GLN within it. Companies have
different length GLNs depending on how many SKUs they have.
"GTIN" is the product UPC number.
"GLN" is the part of the UPC that is the company's unique ID number.
CertainTeed's GLN is 772677
