For customers who may have multiple messaging use cases, below is our guidance on how to register multiple use cases for A2P 10DLC.
Can I use my phone numbers for multiple Campaigns?
Phone numbers can only belong to one A2P 10DLC Campaign at a time. Twilio manages this by requiring your Twilio numbers to be associated with an approved Messaging Service in order to belong to a Campaign. You may move numbers between different Campaigns, but a given number can only belong to one Campaign at a time.
What if I have phone numbers used across different use cases?
If your phone numbers are being used for different use cases (i.e. 2FA and Customer Care) you can register for a “Mixed” Campaign use case. Please keep in mind that a “Mixed” use case is likely to have a lower throughput than a Declared use case, and slightly higher cost per message due to higher carrier fees (see throughput info and pricing info). If you do a large volume of messaging, it may make sense to separate your messaging use cases into separate Campaigns.
Where can I find a full list of Campaign types and use case descriptions?
You can find a full list of Campaign types and use case descriptions in our List of Campaign Use Case Types for A2P 10DLC Registration.
How do I register for a “Special” Campaign use case?
Right now "Special" campaign use cases are not yet fully supported by the ecosystem. For the latest information and updates please see Special Use Cases for A2P 10DLC.
