How do I find my MATLAB License number?

If MATLAB is already installed:
Within the MATLAB command type "license" and hit enter to view your License number in the output. 
If MATLAB is not installed:
On the My Account page you will see there is a "My Software" section that lists up to 5 License numbers. If you are linked to more than 5 licenses click on the "View additional Licenses or Trials" link to see the full list of licenses you are linked to.
The License Center allows you view all the Licenses associated your MathWorks Account. 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 also listed within the "Trials" section 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 in is 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. We recommend using the browser Chrome. 
Alternatively, if you have received a License File from your License Administrator, the File may contain the License number. Open the License File with plain text editor; the License number should be near the top of the File:
​# LicenseNo: XXXXXX
If you are still unable to determine 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.
If you are still having trouble finding your License number, please contact MathWorks Support:

I have two student licenses (one for my desktop and one for my laptop). I want to buy the control systems toolbox for my laptop, how can I determine which license number corresponds to it? The command "license" just returns "student".

If you visit
do you see both licenses listed? If you do, then click the fork-and-knife icon ("Manage") on one of them, and then Install and Activate. On the right side of that page, click "View Current Activations". If all has gone well, that would bring you to an Activated Computers list, that would have a table that included HostID, that you could match against either the ethernet MAC or the hard drive serial number (older systems.) Then you would back out to get to the other license and go through the chain of items to get to the HostID of the activations of the other license.
Unfortunately I cannot give you a direct URL on mathworks to get the activation list. The URL looks like https://www.mathworks.com/licensecenter/licenses/XXXXXX/YYYYYY/activations where XXXXXX is a license number and YYYYYY is a different number whose internal purpose I have not been able to determine as yet.
As you are using a Student license, I do not know if you can see much of those menus at all.

Ciao, this is Heungsun Choi B, Korean, a doctorate student. I'd purchased Matlab r2006a 2 years ago, from a US vendor. Matter is that, when I try to install it, there is no license number; neither in the package nor in its sleeve. There is mere a license agreement letter w/o license number. For that reason, I havn't install it yet. How can I get the license number? It's totally incomplete K.
Regards.

Please contact Mathworks support for license assistance.
However I am concerned that you might not have purchased an authentic license. Mathworks would not have sold you a 2006 license two years ago, and Mathworks is the only USA company authorized to sell licenses. The market for legal used licenses is restricted to a couple of EU countries such as Denmark and Germany.

If the license is associated with you personally (that is, was not associated with the University that you are no longer at), and you are still considered educational (if that is what the license was), then the license is probably still valid, covering up to the last release that you paid support for. I say "probably" because universities sometimes purchase year by year instead of permanent licenses.
For such an old license, you would need to get assistance from Mathworks Support to generate an installation key for you.
2000 would have been R11.1 (November 1999) or R12 (November 2000) and with the usual one year of support that is included with licenses, might even extend to R12.1 (June 2001).
Once the license is associated with your MATLAB Central account, you would be able to download R11.1 or R12.1 (but not R12) from https://www.mathworks.com/downloads/web_downloads/select_release?mode=gwylf
You might have to dig up proof of purchase in order to get Mathworks Support to associate the license with your account.
If it was an educational license you had then, and if you are still educational, then because R12* is so old, I would recommend that you instead purchase a new educational license. Releases that old do not work properly in Windows Compatibility Mode, and there are additional software requirements that would not be easy to meet at this time (Netscape Navigator for example)

How to know which license number is linked to which mail? Because when I typed the command 'license' in the command window, it showed me a number, but when I was trying to link it to the mathworks account it was showing license key does not match.

I would recommend calling Customer Service or visiting our chat line with the license number in question. They will be able to tell you who is associated to that license.

The volunteers who answer questions here do not have access to the license database. You need to contact Mathworks if you purchased MATLAB directly from Mathworks. If your MATLAB is supplied by a university or institution then you need to contact their IT departments.

Student licenses do not have a license number: they use activation keys.
