Can my Twilio number send SMS to a non-Twilio short code?

Question

Product

Programmable Messaging

Answer

No. Twilio numbers cannot send messages to short codes at this time whether they are Twilio short codes or external short codes.

Can a Twilio short code receive messages? Yes, but only from standard mobile subscriber devices (like personal cell phones), not from other virtual or programmatic long-code numbers.
How should I collect user opt-ins? If you use a short code for your business, ensure your end-users subscribe using their personal mobile devices rather than automated business numbers.
