Compliance considerations

Because Turkish carriers are filtering traffic with numeric and unregistered alphanumeric sender IDs, be sure to pre-register your Alphanumeric Sender ID to ensure message delivery. Person-to-person (P2P) traffic, as well as content related to gambling, political, and religious topics is prohibited.

In addition, all messages used for advertising or marketing must follow these regulations: 

  • Preface messages with ‘REKLAM:’ or ‘TANITIM:’ to alert the recipient that s/he is receiving a promotional message.
  • Include the company’s URL or customer care number, and inform recipients where to find details about the campaign or promotion being advertised.
  • End the SMS with an option to opt out.

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.
