How do I find my license serial number?

Updated

This article helps Unity Plus, Pro, Industry, or Enterprise users locate their license serial number when prompted during activation. It explains the difference between Named User Licenses and serial key-based licenses, and when a key is needed. The article guides users through finding their serial number based on where their subscription is managed—either through the Unity Dashboard or Unity ID. It also provides steps for users who haven’t been assigned a license seat or can’t locate their purchase email. ✨

 
Cause:

To use Unity, you’ll need to activate a license. Unity offers two types of licensing systems: the modern Named User Licenses (NUL) and the legacy serial key-based model.

Named User Licenses, commonly used with Industry, Enterprise, and Pro plans, are directly tied to your Unity ID once a seat is assigned. No serial key is needed; activation happens automatically when you sign in to Unity Hub.

That said, you might still need a serial key if you’re activating an older version of Unity or working in a restricted network environment where manual activation is required.

Important: Unity Personal license users do not have a serial key and can only be activated by logging in to the Hub. For more information, see the article 'How do I activate my license?'.
Resolution:
 
For Unity Pro, Industry, and Enterprise license users:
 
Usually, you can find your serial number in the email you are sent after your seat is assigned.
If you cannot find your seat assignment email, ask the Owner or Manager of your Unity organization to assign you the license seat, then follow the steps below:
The resolution differs depending on where your Unity Pro subscription is housed. 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

  1. Navigate to cloud.unity.com and sign in using your Unity ID credentials.

  2. Using the left-hand menu, select Administration.

  3. Select Subscriptions.

  4. If you have a User role within the organization, your license key appears to the right of the organization subscription.  
    If your current organization role is Owner or Manager:

    2. Your license key is displayed under the "Users with seats" section of the screen in the Overview tab. Use the copy icon to the left of your serial number to copy the key to your clipboard.

If you cannot find your serial number or subscription, first, ensure that you are viewing the correct organization by 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.


If your subscription is housed under id.unity.com, follow the steps below:

  1. Sign in to your Unity ID at id.unity.com.

  2. Select My Seats from the left side menu. Your serial number is visible on this page.

 
If your serial number does not appear within the My Seats section, ask the Owner or Manager of your Unity organization to assign you a license seat, then follow the above instructions. Alternatively, your subscription may be housed within the Unity Dashboard. In that case, click here for your resolution.
