A2P 10DLC registration has four steps: create a Customer Profile in Trust Hub, register your Brand with EIN and business details, register a Campaign with use case and sample messages, then associate phone numbers via a Messaging Service. Campaign review takes 10-15 business days.

A2P 10DLC applies to US local 10-digit numbers and requires brand plus campaign registration taking 10-15 business days. Toll-free verification applies to US/Canada toll-free numbers, is simpler, and takes 3-5 business days. Both are mandatory before sending SMS.

Common rejection causes include vague campaign descriptions, sample messages missing opt-out language, inaccessible opt-in links, URL shorteners like bit.ly, and privacy policies stating data is shared with third parties. Failed campaigns can be edited directly in the Twilio Console.

No, Twilio Verify is exempt from A2P 10DLC registration and works immediately without any sender registration. This exemption applies only to Verify traffic, not to standard messaging sent from 10DLC numbers.

Error 30034 means a message was sent from an unregistered US 10DLC number. The fix is to complete A2P 10DLC registration, including brand approval, campaign approval, and associating the phone number with the campaign through a Messaging Service.

No, Branded Calling is mobile-only. In the US it is in Public Beta on T-Mobile and Verizon, and non-US availability varies by country and carrier. For landlines, use CNAM to display your business name on caller ID instead.
