How are File Numbers and Volume Numbers different?

  1. File Number: The highest level of UL's client organizational structure. A file is "folder" with an alphanumeric designation in which client project information is referenced Generally speaking; all project information per Applicant (9-digit Subscriber Number) within a CCN is referenced within a single file.
  2. Volume Number: The second highest level within UL's client organizational structure. A volume is a "sub-folder" within a File. The Applicant, Listee(s) and Manufacturer(s) who have been identified for each safety project are referenced at the Volume level. Projects grouped together within a Volume must share the same CCN, Applicant, Listee(s) and Manufacturer(s). Any deviation will result in a new Volume (and sometimes a new File). One Procedure typically exists for each Volume. (See also Alternate Listee and Multiple Listees).
