A2P 10DLC number registration FAQs
What happens if I don’t register in time? | As of July 2023, all messages sent with unregistered 10DLC phone numbers are subject to gradual message blocking by Twilio. There will be a full block of all unregistered US-bound messages sent after August 31, 2023. Your messages will bounce back error code (30034) and you will still be charged Twilio messaging rates.

What alternatives do I have to registering my A2P 10DLC number? | As an alternative to A2P 10DLC, you can use other number types like short codes, WhatsApp Messaging, Twilio Verify API, and toll-free phone numbers. A lot of customers are seeing success with toll-free numbers because they can be used for any use case. They provide high-throughput SMS once verified and are voice enabled. And the verification process is handled by Twilio and usually takes less time than 10DLC approval. You can complete the toll-free verification via Console or API. |
Why is the verification process taking a long time? | Campaign registrations are taking longer because there’s a human review process conducted by Twilio and our external vetting partner to manually check all the information provided by senders, review, and approve it. |

Who approves the registration requests? | Twilio works with external vetting partners to review and approve 10DLC brand and campaign registration requests. |
