Compliance considerations

Dynamic Alphanumeric Sender IDs are supported, although sending with Numeric Sender IDs will be attempted on a best-effort basis. We recommend sending with an Alphanumeric Sender ID specific to your brand and content. The Nigerian Communication Commission mandates that Nigerian telecom operators implement a do-not-disturb (DND) registry which allows customers to opt out of either receiving promotional messages or unsolicited messages via SMS in general. Depending on the DND features that the subscriber has selected, attempts to send promotional and unsolicited SMS to those numbers may fail. Twilio provides special routes with permission to contact phone numbers on the DND list by SMS when the traffic is classified as One-Time Password (OTP). Please consider:

  1. Unsolicited messages are not allowed via this route. Your recipients must have expressed permission (i.e., opted in) to be contacted via SMS.
  2. A phone number on the DND list might also be switched off, out of network coverage, or simply dead. The delivery report will indicate the status of messages sent to phone numbers on the DND.

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.
