A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Does Twilio maintain Do Not Call lists?

It is the responsibility of the project owner to adhere to the local laws and regulations regarding "Do Not Call" lists. Twilio does not handle these lists and we do not refuse attempts to call and send messages to these phone numbers.

If you try to send an SMS message to a phone number on a "Do Not Call" list, Twilio will attempt to send these messages. Messages may show up in your logs as "Sent". However, if the 'To' number is on a Do Not Call list, these messages may be filtered by the recipient's carrier.

We recommend that the project owner maintain and update their own calling and SMS messaging lists so that it is up to date with the phone numbers on the "Do Not Call" lists.
