Sending SMS to landline numbers
How Twilio handles an SMS message destined for landline telephone number.

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
Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. This table lists some general best practices.

Message delivery to M2M numbers is on best effort basis only.

French mobile networks block marketing SMS traffic between 10pm and 8am, on Sundays, and on French public holidays. If messages are sent during these restricted times, they will be queued and sent the following day.

The use of URL shorteners such as bit.ly or tiny.url may produce SMS filtering in France. We suggest our customers using the full form of the URL instead.

Sending adult content, controlled substance, and cannabis related content is strictly prohibited.

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. For France, a web link in the message is also accepted as an OPT-OUT method.
4. Do not contact end-users on do-not-call or do-not-disturb registries.

Use case restrictions

French domestic Long Codes can only be used for person-to-person (P2P) messages. Using it for any high volume messaging, or even for application-to-person (A2P) messages, will result in delivery failure and the domestic Long Code being blocked.

For French domestic long codes, it's recommended to maintain a balanced ratio of outbound to inbound messages to prevent carrier filtering.

French mobile operators do not support message delivery via international Numeric Sender ID. Submission by International Long Codes will be attempted on a best-effort basis. The Long Code will be overwritten with a generic Alphanumeric Sender ID or Short Code outside the Twilio platform.
