What is A2P 10DLC and why does my business need it?#
A2P 10DLC is the US carrier program that lets a business send texts from ordinary 10-digit local numbers. Carriers deliver business texts from local numbers once two things are on file: the brand (who you are) and the campaign (what you send and why). Register both and your appointment reminders, missed-call text-backs and AI follow-ups reach phones instead of a carrier filter.
How do I register my brand and campaign in Agent Studio?#
You fill two short forms on the A2P 10DLC registration panel and submit. The brand form comes first; once a brand is saved, the panel switches to the campaign form.

How do dry run and live submission work?#
Numbers, carrier registration and dialer calls run through your Twilio account. Until you tick Submit A2P 10DLC registrations to the carriers in the Provider panel, a submission is a dry run: you see the full flow and a Dry run pill, and nothing goes to the carriers. Switch it on when your details are final.
