Is it possible to add numbers after A2P registration.
Hello! I am registering A2P for my company and I am wondering if my numbers will also be added to A2P if I buy them after A2P registration. If not, please let me know if they can be added after registration, perhaps via API. I am not an ISV, I am a direct brand.
You will need to add them individually to a Message Service after purchasing a new number. You can add them either using the REST API or the website Console.
Any numbers that you add to that Messaging Service will be automatically associated with the approved Campaign. For help adding numbers to a Messaging Service, see How Do I Add Numbers to a Messaging Service. Not sure which numbers remain unregistered?
