# Optional: acting as Reseller
If you are registering a 10DLC campaign on behalf of third parties (e.g., your clients), you are required to also include your own contact information as part of the registration process. You can do so by including a `resellerId` in your POST campaign calls
{% hint style="info" %}
The Reseller ID is a unique value to be shared by all workspaces, all brands, and all campaigns created under your Organization.
* If you operate as a reseller you only need to obtain a reseller UUID once and reuse it in all your requests
* If you intend to register one or more brands (for example multiple branches of your company) for your internal use you can NULL the field
{% endhint %}
You can create and manage your Reseller information via the UI when creating a campaign
you can retrieve information via the following method
{% hint style="warning" %}
Ensure your reseller status is active before creating a campaign with it
{% endhint %}
