What the calls are
- Automated-voice public-opinion and awareness surveys
- Also used as the sender of survey-related SMS notifications
This site previously described the number as used-car purchase sales calls. After re-verification against the operator's official website, we corrected the attribution to survey calls.
If you receive a call
Answering opinion surveys is voluntary; you can simply hang up. Legitimate surveys do not normally ask for bank-account numbers or PINs, so if any question involves money, do not answer and consult the police consultation line (#9110).
