If MATLAB is already installed:
The MATLAB command "license" will output your license number.
If MATLAB is not installed:
Go to http://www.mathworks.com/licensecenter/ and sign into your MathWorks account. This page will display all the licenses that your MathWorks Account are linked to. If you do not see any licenses on this page then click the "View Full License List" in the upper right hand corner of the screen.
If you still do not see any licenses in the license center:
- Make sure you are viewing the correct section of the License Center. Trial licenses are listed separately from Professional and Academic licenses. You can change this view using the drop down menu with orange text in the upper left hand corner of the License Center.
- You may be logged in with a different email address than the one your license is linked to. It is not unusual for people to have multiple MathWorks accounts, e.g. one for work and one for school. Click on your name in the upper right hand corner of the screen to confirm that the account you are logged with the correct email address.
- Your browser may have stale cache data or old cookies. Clear your browser cache, or sign in using a different web browser.

If you are still unable to ascertain your license number, speak with the members of your organization responsible for software license management. With some MATLAB license types, associating users to the license is optional, and in this case the license would not appear in your License Center.
