When your agent calls or messages people, you are the caller in the eyes of the law. ThinnestAI gives you tools that help you keep to the rules, but it does not decide whether you may call someone, and it does not check for you. This page sets out which part is which, country by country.
This is not legal advice. It is a short guide to rules that change, and that apply differently to marketing calls, service calls and calls a customer asked for. Check with a lawyer who knows your market before you run outbound calls, and read the regulator’s own guidance linked below.

​
What the platform does for you

  • A do-not-contact list. Numbers on the list on the Contacts page under Do not contact are never reached by a campaign or an API call, on any channel. It is checked as each call is placed, so adding a number stops a campaign that is already running. See Calling campaigns.
  • “Don’t call me again.” When a caller clearly asks not to be called again, your agent puts their number on that list itself, unless you switch this off for the agent. See “Don’t call me again”.
  • Opt-outs. Anybody who has asked you to stop is left out of a campaign even when they are in the file you upload.
  • Calling hours you set. A campaign calls only in the hours you give it, and an API call only in the callingHours you send. Hours are read on the called person’s clock, worked out from their number: 9am on a London number means 9am in London. For a country with several time zones, such as the United States, a campaign keeps inside your hours at both ends of the country. See When it calls, and when it stops.
  • Pacing. A cap on calls per hour, and retries that keep to your hours.
  • Honest about being an AI. If someone asks whether they are talking to an AI, a bot or a real person, the agent says it is an AI assistant, on every channel and whatever your instructions say. See Behaviour.

​
What the platform does not do

  • There are no calling hours of our own. A campaign with no hours set, or an API call with no callingHours, may ring at any hour. Set hours that keep to the law where the person you are calling lives.
  • No register screening. We do not check your lists against the US National Do Not Call Registry, the UK’s TPS or CTPS, India’s DND register or any other register.
  • No consent check. Ticking “these people agreed to be called” when you upload a list is a claim you make and we record. We do not verify it.
  • No automatic announcements on phone calls. An agent does not say on its own that the call is recorded or that it is an AI. If the law requires either, put it in your agent’s first words. (Website calls show This call is recorded when recording is on, and an agent always answers truthfully if a caller asks whether the call is recorded.)

​
United States: TCPA

The Telephone Consumer Protection Act (TCPA) and the Federal Communications Commission’s (FCC) rules decide most of what an outbound AI call needs. Read: FCC: Telemarketing and robocalls and the National Do Not Call Registry.

​
United Kingdom: PECR

Marketing calls in the UK are governed by the Privacy and Electronic Communications Regulations (PECR), enforced by the Information Commissioner’s Office (ICO), alongside UK GDPR for the personal data itself. Read: ICO: direct marketing and PECR and the Telephone Preference Service.

​
India: TRAI

Commercial calls in India are governed by the Telecom Regulatory Authority of India’s (TRAI) rules on unsolicited commercial communication, alongside the Digital Personal Data Protection Act for the personal data. Read: TRAI, where the regulations on unsolicited commercial communication and the DND register are published.

​
The UAE and other countries

Every country has its own rules on telemarketing, consent, Do Not Call registers and calling hours. The UAE, for example, has its own telemarketing regulations and a Do Not Call Registry. For anywhere not covered above, the hours you set on your campaign are the only hours the platform keeps to, so check the local rules before you call.

​
Where this is written down

Our Terms of Service (section 6) put consent, Do Not Call screening, calling hours and disclosures on the business that places the calls, and the Acceptable Use Policy lists what may never be done. If you resell ThinnestAI under your own brand, your clients’ calls are yours to answer for too.
