A2P 10DLC registration required for US messaging - SMS Solution for a non-US party with Twilio
A new regulation for SMS in the US caused a high level of SMS delivery failure. If initially using a Local number as origin, Twilio will advise users to complete A2P 10DLC registration, which is troublesome for most small businesses. Switching to a Toll-free number might be a better solution.
Type of Messaging Origin
- Long codes (A2P 10DLC)
- Short codes
- Toll-Free numbers
Toll-Free Number is more practical
