Compliance considerations

Due to local carrier restrictions, sender IDs will be overwritten into a random short code for all SMS traffic to New Zealand. Deliverability over random shortcode is on best-effort basis. If you are sending mission criticial and time sensitive messages it is highly recommended that you reach out to Twilio for further details on how to get dedicated shortcodes.

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.
