Sending SMS to landline numbersTwilio will not check whether the number is a landline and will attempt to send it to our carrier for delivery. Some carriers will convert the SMS into text-to-speech messages via voice calls.
Compliance considerations

Twilio recommends sending application-to-person (A2P) traffic over short codes or verified toll-free numbers for optimal delivery results. Canadian mobile carriers enforce strict filtering on A2P messages. Carriers will not cease filtering, but mobile subscribers may wish to reach out to their mobile carrier to petition them to do so.  

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices:

  1. Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications.
  2. Only communicate during an end-user’s daytime hours unless it is urgent.
  3. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language.
  4. Do not contact end-users on do-not-call or do-not-disturb registries.
