Does an E-number on a product mean that it is UL Listed?
No. The UL E-number is a valid identifier for the organization responsible for a product but not an indication that the product is Listed, Classified, verified or Recognized. Only the appropriate UL Mark — on the wire or cable or on its packaging — is a valid indication of UL certification. UL assigns a unique E-number (E and a 3- to 6-digit number for wire and cable products) to each applicant in every product category. To find the responsible organization for a product when the E-number has been used for identification, go to UL’s Online Certifications Directory, select “Search By UL File Number” and enter the E-number.
