‌Where is my Zemax license number?

  • Your license number is in the format of “L1XXXXX” or a five-digit number such as “22000”.
  • If you currently have a Zemax application installed, your license number is located in the “Help” and “About” sections, or from the Zemax License Manager application.
  • If you have a USB license, it is printed on the USB itself.
  • If you do not have the software installed yet and are trying to access a shared network license at your organization, we recommend you acquire the license number from a colleague using that license.
