How Phone Check Works

Discover how we verify your phone number against known data breaches to help you stay safe online.

Phone Scan Phone Number Breach Detection

Your phone number is never stored or logged by our system. It is normalized and checked against our breach database to determine if it has appeared in any known data leaks.

1

Phone Input

You enter your phone number in any format. The system strips all non-digit characters and normalizes it before processing — only digits are kept for an accurate lookup.

Input: +20 (010) 1234-5678
Normalized: 201012345678
2

Server Submission

The normalized phone number is securely sent to our server over an encrypted HTTPS connection. The number is used only for the breach lookup and is never stored or logged.

Sent: 201012345678
Encrypted via HTTPS

Database Lookup

The phone number is checked directly against the breach database on the server. The system scans for an exact match and returns whether a match exists and the associated breach information.

Server lookup: exact phone match
Result: FOUND / NOT FOUND

Results Report

You receive a full report showing whether the number was found, how many breaches matched, and which data breach databases contained it — your number is never stored or logged after the check.
