A2P 10DLC Campaign Vetting Delays: We are experiencing delays while vetting 10DLC campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Twilio is working with the provider to help expedite this process. New details will be shared in our incident report as soon they become available.

Can I Block Specific Numbers from Sending Messages to my Short Code?

No. Short codes should be able to receive incoming messages from any mobile numbers within their reach. This is because a short code must always be able and ready to respond to required keywords like STOP and HELP.

For example, a United States short code can reach numbers on most US mobile carriers, so it should be able to respond to messages from those users as well.

Notice: Deliberately blocking any messages or senders on a short code creates a compliance risk and is not permitted.
