# Register a subscription

{% hint style="warning" %}
**Note:** The license key should be registered in the business account of the organization that purchased the license. If you require assistance from third parties,  you can add their representatives as license administrators on the same license as described in [**Inviting users to join a business account**](https://docs.parallels.com/landing/ras-licensing-guide/v20/manage-accounts/inviting-users-to-join-a-business-account). This will allow them to view and manage the license key.
{% endhint %}

If you would like to register a business subscription using your existing business account, do the following:

1. Sign in to Parallels My Account using your email address and password.
2. Click **Register Key** on the page header.
3. Input your license key and click **Register**.

Your subscription is now registered and can be used to activate a Parallels RAS farm.
