Compliance considerations

Dynamic Alphanumeric Sender IDs are supported, although 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 receiving promotional messages. Any attempt to send promotional SMS to those numbers will fail. Twilio provides special routes with permission to contact phone numbers on the DND list by SMS when the traffic is classified as OTP (one-time password). Please consider:

  1. Unsolicited messages are not allowed via this route. Your recipients must have expressed permission (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, particular 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.
