Unity requires license activation via Named User Licenses (linked to Unity ID) or legacy serial-key licenses. Named User Licenses auto-activate with Unity Hub sign-in and are device-flexible, while serial licenses are machine-locked and need manual return for reuse. Pro, Industry, and Enterprise users find serial keys in seat assignment emails or via their Unity organization dashboard on cloud.unity.com or id.unity.com. If missing, contact the organization owner or Unity support for assistance.
To use Unity, you’ll first need to activate a license. Unity offers two licensing systems: the modern Named User Licenses (NUL) and the legacy serial-key based model.
Named User Licenses
These are used with Unity’s Personal, Pro, Industry and Enterprise plans. The license is linked directly to your Unity ID, eliminating the need for serial keys.
- The license is automatically activated when you sign in to Unity Hub.
- It is automatically returned when you sign out of the Unity Hub.
- This makes it easy to switch between devices without managing activations manually.
Serial-Based Licenses
This is the older system that uses a serial key that you can use to activate through the Unity Hub or via the command line.
The license is locked to the machine it’s activated on.
To reuse it on another device, you must manually return the license from the original one.
Some users may prefer this method for scenarios such as automated testing and builds, or situations that require a manual activation due to network restrictions and offline environments.
If you’re activating an older version of Unity, you might still need a serial key to activate.
| Important: Unity Personal license users do not have a serial key and can only be activated by logging in to the Hub (NUL). For more information, see the article 'How do I activate my license?'. |
| The resolution depends on where your subscription is hosted. If your subscription is housed under the Unity ID portal (id.unity.com), click here to jump to your resolution. |
If your subscription is housed under cloud.unity.com, follow the steps below
Navigate to cloud.unity.com and sign in using your Unity ID credentials.
From the Home screen, select Manage organization.
Select My Products from the left-side menu.

Your license serial key is displayed within the My license section.
If you cannot find your serial number or subscription, first ensure you are viewing the correct organization using the org switcher in the top-right corner of the dashboard. If your serial number still does not appear, ask the Owner or Manager of your Unity organization to assign you a license seat, then follow the above instructions.
