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.

Effective April 25, 2023, dynamic Alphanumeric Sender IDs won’t be allowed in Australia. All Alphanumeric Sender IDs must be pre-registered to send messages in Australia. Messages sent using Alphanumeric Sender IDs that aren’t pre-registered by April 25, 2023 may be blocked.

To pre-register with Twilio, head over to https://twlo.my.salesforce-sites.com/SenderId to provide the necessary proof that you are entitled to use the Alphanumeric Sender ID and other documents. 

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to ensure they comply with all applicable laws. Sending gambling related content is strictly prohibited in Australia.

Unsolicited Communication: All commercial electronic messages sent to an electronic address in Australia are beholden to the SPAM Act (2003). It is a partner’s responsibility to familiarize yourself with this legislation and ensure your compliance; the key rules relating to this can be found at https://www.acma.gov.au/theACMA/spam-industry-obligations and below: - Permission (consent)—messages can only be sent with the permission of the person who owns the account for the address (usually the recipient). - Identification—messages must contain the name and contact details of the person or business that authorized the message (sender identification). - Unsubscribe—messages must contain a low (or no cost) way for the recipient to stop getting messages (to ‘opt out’ or unsubscribe).

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.
