Compliance considerations

Saudi Arabian networks have implemented strong filtering that blocks messages coming from Numeric Sender IDs, messages that contain objectionable content, and messages that contain URLs. Messages sent with identical content to a recent message will also be blocked. To avoid the possibility of messages to users in Saudi Arabia being blocked, be sure to pre-register your Alphanumeric Sender IDs. 

Twilio is unable to register Sender IDs on behalf of domestic brands based in Saudi Arabia because of a new regulation that prohibits the re-selling of domestic traffic. 

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.

Use case restrictions

Twilio is unable to register Sender IDs on behalf of domestic brands in Saudi Arabia due to a new regulation that prohibits the re-selling of domestic traffic. 

If you use Alphanumeric Sender IDs for promotional purposes such as advertising or marketing, you must affix '-AD' to the Sender ID; for example, 'Twilio-AD' instead of just 'Twilio'. 

Adult content and gambling or virtual gambling content is prohibited. Messages containing such content will be blocked, and the account may be blacklisted.

Alphanumeric is only supported through pre-registration.

Numeric Sender IDs will be overwritten with generic Alphanumeric Sender IDs outside Twilio's platform.

Best practices

If the Sender ID requested is different than or not affiliated with the company requesting the Sender ID, you must submit documentation that proves the company is allowed to use the Sender ID's brand name. 

For example, Twilio owns the brand 'Authy'. When Twilio submits a registration request for Authy, it needs to submit a document that proves Twilio owns the rights to use the Authy brand name.

Preregistration required.
