I have a Campaign Verify Token, but I am unable to use it to register Political Use cases. Why?

A Campaign Verify token can be used only once per texting platform.

If you have used the Campaign Verify token on another platform similar to CallHub, you will not be able to use the same token while registering 10DLC on CallHub.

You need to re-register with Campaign Verify and obtain a new token that you can use while registering a 10DLC Political use case on CallHub.
