A2P 10DLC - Not Registered
All local U.S. phone numbers used to transmit SMS and MMS messages to other U.S. phone numbers must be fully registered to an approved A2P10DLC Campaign under your brand.
Messages transmitted from unregistered phone numbers have been subject to a progressive increase in message blocking by carriers since July 5, 2023. These changes affect all providers in the industry.
If you notice your messages fail to send or don't appear to be received, even if they have left the smrtPhone system, you need to take action as soon as possible. Please check in with our Support team via Live Chat to check the status of your outbound messages.
All smrtPhone clients must register their business profile in the Trust Center, and if you want to send text messages, you must also register for A2P10DLC.
The registration process requires time for verification and validation, and when completed, you will be able to send messages again.
Any text containing a forbidden word will be automatically blocked by our system. Hence, your text will not be delivered, and you will get an error notification.
For security reasons, smrtPhone will not publish any list containing the forbidden words, but you can learn more about How to keep your messages compliant by reading our article here. ⇢
