NumLooker is a reverse phone lookup service that allows users to identify unknown callers across the United States. By entering a phone number, individuals can access a report that may include the owner's name, age, address, email address, and potential relatives. The service aggregates data from over a billion public records to provide this information. While primarily used to identify unknown callers and avoid scams, the availability of this personal information poses privacy risks. The exposure of such data can make individuals more vulnerable to identity theft, stalking, and harassment. Bad actors could potentially use this information to create more convincing phishing attempts or for doxxing purposes. To protect their privacy, individuals should be cautious about the information they share publicly online and can request to have their information removed from NumLooker's database.
