A2P 10DLC Compliance Policy
Understanding the rules of business messaging in the US.
What is A2P 10DLC?
Application-to-Person (A2P) 10-Digit Long Code (10DLC) is a system introduced by US carriers to protect consumers from spam while allowing legitimate businesses to send messages with high deliverability.
All AstroVoice customers sending traffic to US numbers must register their Brand and Campaign. Unregistered traffic is subject to severe blocking and pass-through fees.
Prohibited Content (SHAFT)
Carriers strictly prohibit the following content. Attempting to send these will result in immediate bans:
Requirements for Approval
Opt-In Consent
You must obtain explicit consent from recipients before messaging them. This can be via a web form, keyword (e.g., 'Text START to 5555'), or written contract.
Opt-Out Mechanisms
All campaigns must support standard opt-out keywords like STOP, CANCEL, or UNSUBSCRIBE. AstroVoice handles this logic automatically.
Privacy Policy
Your website must have a visible Privacy Policy stating that you do not sell personal data to third parties.
