Hi Chris,
To answer your question, look to your UL Follow-Up Service Procedure (FUSP) and
find the "Listing
Mark Data" page. This page details the composition and elements of the UL
Listing mark, which are:
1. UL in a circle (the famous UL Listing mark symbol),
2. The word "LISTED" in capital letters,
3. The assigned control number*, and
4. Product identity (e.g., NWGQ, I.T.E., etc.)
* The assigned control number is a designation that UL assigns to a
manufacturer, or manufacuring
location (I have also seen UL file numbers used here, although I'm not sure
that UL objects to
that).
So, given the above and IMHO, I would say that just a generic UL Listing mark
would neither be
acceptable nor authorized by UL. However, I recommend contacting UL for their
official position on
the use of their Listing mark.
I hope this answers your question.
Best regards,
Ron Pickard

Please respond to

This thread brings up a question that I have been wondering about.
Amund's question dealt with a product that had the UL label and a file
number. The file number was used to identify the manufacturer. My
understanding of the response that Amund received is that this
identification is adequate
My question is:
Does the file number need to be on the label? Can the manufacturer
leave the file number off of the label and simply put a generic UL (or
CSA) mark on the product along with their nameplate identifying the
manufacturer, model and serial number?
If this can be done, are there any sources for pre-printed UL and/or CSA
labels? I'd especially be interested in one with the CSA mark and the
"C US" subscript denoting dual UL/CSA certification. These days,
management likes using less custom parts and saving money. Even if it's
labels :-)
