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.

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. Promotional messages should only be sent between 09:00am and 08:00pm local time. Messages sent to mobile numbers registered in the DND list will be filtered.

Sending gambling, adult content, money/loan, political, religious, controlled substance, cannabis, and alcohol related content is strictly prohibited. Messages containing WhatsApp/LINE chat links, and phone number in body are not allowed.

Twilio is unable to register Sender IDs on behalf of domestic brands based in Saudi Arabia or Qatar 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, 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.

Use case restrictions

Starting from April of 2024, the network MOBILY has stopped supporting Promotional Sender ID Registration.
Twilio will continue supporting this type of Registration only for the rest Saudi Arabian networks.

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.


If you use an existing Alphanumeric Sender ID for transactional purposes, but choose to use it for promotional purposes too, then you have to register another Account SID and register a new Sender ID which will be dedicated to promotional traffic only. You must also affix -AD to the Sender ID: for example, Twilio-AD instead of just Twilio. 

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

Due to limitations related to the local infrastructure we suggest our clients to use UCS2 encoding when submitting messages containing the EURO symbol "".

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

N/A

Best practices

URLs in the message content must first be allowlisted. Sending messages with URLs without adding them to an allowlist may result in delivery failure.

If the requested Sender ID is different to the name of 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 provide a document which proves that Twilio owns the rights to use the Authy brand name.

Twilio requires customers to use a registered Alpha Sender ID in Saudi Arabia.
