Sending SMS to landline numbers |
You cannot send SMS to a landline destination number: the Twilio REST API will throw a 400 response with error code 21614, the message will not appear in the logs, and the account will not be charged. |
Compliance considerations |
Sending gambling, adult content, money/loan, political, religious, controlled substance, cannabis, and alcohol related content is strictly prohibited. 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:
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:
