license transfer

hello. i have a unity pro license at work and unity basic license at home. Sometimes I have to work from home, so I need to activate my unity pro on my personal computer. Does anyone know where I can find my serial number so that I can activate it at home.

thanks

In the mail you got after ordering it.
Unity itself doesn’t show it.

just be aware that only 2 installs are possible. after that at least one has to be deactivated by UT
