What it detects
What FileSentinel finds
FileSentinel detects phone numbers across common formats and scores them against the surrounding personal data. A contact list packed with numbers is escalated, while a one-off number in a footer stays low priority.
Where it hides
- Spreadsheets and CSV exports
- Text and email exports
- Word and PDF documents
- Scanned forms (via OCR)
Why it matters
The risk of leaked phone numbers
Phone numbers are personal data and, gathered in bulk, enable smishing and unwanted contact. They build up in contact exports, call logs, and customer records.
- Contact and customer exports
- Call logs and support records
- Mailing and registration lists
- Scanned forms collecting contact details
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags phone numbers with a confidence and severity score, and helps you remediate. Built-in detectors cover the common cases, and a custom rule builder lets you add plain-text or regex detectors for anything specific to your work.
Every finding gets a confidence and severity score, so real phone numbers rise above coincidental matches.
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching phone numbers in screenshots and scans.
Redact values, mark false positives, or export a CSV, HTML, or PDF report, then share with confidence.
Private by design
Your files never leave your PC
Scanning, OCR, and remediation all happen on-device. FileSentinel makes no network connections to do its work, so the very data you are trying to protect never has to leave your machine to be checked. No server, no cloud, no upload step.

Find phone numbers FAQ
How do I find phone numbers in my files on Windows?
Install FileSentinel from the Microsoft Store, point it at a folder or drive, and start a scan. FileSentinel reads inside your files, flags phone numbers, and scores each finding by confidence and severity so the real risks rise to the top.
Is scanning for phone numbers private?
Yes. FileSentinel runs entirely on your device. Scanning, OCR, and remediation all happen locally with no uploads and no cloud, so the data you are trying to protect never has to leave to be checked.
Does FileSentinel handle international and formatted numbers?
It recognises phone numbers across common formats and scores them by context. For a specific numbering format you need to track precisely, the custom rule builder lets you add a regex detector.
What file types does FileSentinel check for phone numbers?
FileSentinel reads inside documents, spreadsheets, text, and PDFs, and with OCR enabled it reads text inside images and scanned PDFs too, so phone numbers captured in a screenshot or scan is caught as well.
