TCPA and opt-out rules for business texting.
A plain-language overview of the Telephone Consumer Protection Act as it applies to texting, and how STOP/opt-out works in practice.
The Telephone Consumer Protection Act (TCPA) is the federal law that governs automated calls and texts to consumers, including a general requirement that businesses have appropriate consent before sending certain texts, and that recipients always have an easy way to opt out.
In practice, the industry standard is the STOP keyword: a recipient replies STOP (or similar) and the sender's system is expected to immediately suppress further messages to that number. Carriers treat this as a baseline requirement, not optional — failing to honor it quickly is one of the fastest ways for a number to get filtered.
Consent and disclosure requirements can carry additional nuance depending on your industry and how a customer's information was collected — this page is a general overview, not legal advice, and you should confirm your specific obligations with your own counsel.
Every TextBox number handles STOP/opt-out automatically and immediately, with no extra setup required on your end.
