Compliance considerations

In compliance with Italian Communications Authority resolution 42/13/CIR, Twilio Ireland Limited (Twilio)  has adopted this Code of Conduct regarding the use of Aliases (i.e., alphanumeric senderIDs) for Business Messaging Services. 

In this context, an “Alias” is a string of alphanumeric characters shown in the CLI field for SMS/MMS and data transfer communications. 

Article 5, paragraph 4 of AGCOM (Italian Communications Authority) resolution 42/13/CIR regarding “Regulations for using alphanumeric caller identification indicators in SMS/MMS used for business messaging services” states that messaging service providers must adopt a Code of Conduct in advance, establishing, among other things, the rules for creating an Alias and the measures taken to protect End Users. 

The Code of Conduct will be regularly updated by Twilio, including but not limited to ensure compliance with any future changes to the regulatory regime applicable to the use of Aliases.

In ottemperanza alla delibera 42/13/CIR dell'Autorità per le Garanzie nelle Comunicazioni, Twilio Ireland Limited (Twilio) ha adottato un codice di condotta in merito all'utilizzo di ALIAS (cosiddetti SenderID alfanumerici) per i servizi di messaggistica aziendale.

In questo contesto, un "Alias" è una stringa di caratteri alfanumerici visualizzata nel campo dell'indirizzo per SMS/MMS e comunicazioni di trasferimento dati.

L'articolo 5, comma 4, della delibera AGCOM 42/13/CIR recante “Regolamento per l'utilizzo degli indicatori alfanumerici di identificazione del chiamante negli SMS/MMS utilizzati per i servizi di messaggistica aziendale” prevede che i fornitori di servizi di messaggistica debbano adottare uno specifico codice di comportamento in anticipare, stabilendo, tra l'altro, le regole per la creazione degli Alias e le misure adottate a tutela degli utenti finali.

Il codice di condotta sarà periodicamente aggiornato da Twilio come e laddove necessario per garantire il rispetto di eventuali future modifiche al regime normativo applicabile all'utilizzo degli Alias.

------------------

Messages sent from international mobile numbers to Italy may be replaced with an Alphanumeric Sender ID or a Local Numeric Sender ID.

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.
