help Twilio Programmable SMS API FAQ
What does Twilio Programmable SMS API actually do?
Twilio's messaging API lets developers send and receive SMS through web service calls instead of building carrier integrations directly. Common uses include login codes, delivery alerts, appointment reminders, and two-way support messages.
Do I need 10DLC registration for US application SMS?
For most application-to-person messaging to US numbers from local 10-digit long codes, 10DLC registration is part of the compliance process. Twilio also supports toll-free numbers and short codes, but those have different approval paths and costs.
How is Twilio SMS different from Twilio Verify?
Programmable SMS is the lower-level API for sending messages you design yourself. Twilio Verify is a higher-level product built specifically for one-time passcodes and verification workflows, including rate limits and fraud controls.
