How do I increase the number of seats on my subscription? – Unity

Symptoms:

I want to purchase more seats on my subscription.
I need to purchase new licenses for people on my team.

Cause:

You may have had more members join your project or team and need to add more seats so that they can use the Editor.

Only the owner of the Unity organization the subscription was purchased on can add seats to a subscription.

Resolution:

The resolution differs depending on the screen you’re directed to upon purchase.

If you clicked Complete onboarding on the final screen when purchasing or your subscription has been migrated to the Unity Dashboard, please click here to jump to your resolution.

Please note: The following steps are for online subscriptions only. If you purchased your subscription offline through the Unity sales team, please get in touch with your client partner directly to buy additional licenses.
