Test if your (US) phone number is in the leaked Facebook data

In plain words

This tool lets US users check whether their phone number appears in a major Facebook data breach. It searches against leaked datasets to determine if personal contact information has been compromised. The service is designed for anyone concerned about their privacy following large-scale social media data exposures. Users can quickly verify their phone number's status without requiring authentication or personal signup.
