Find bank account and routing numbers
FileSentinel surfaces bank account and ABA routing numbers so payment details do not slip out in a shared spreadsheet or PDF.
What it detects
What FileSentinel finds
FileSentinel flags US bank routing numbers and the account numbers that sit alongside them, scoring each finding by confidence and severity. Routing numbers follow a checkable structure, which lets FileSentinel rank genuine banking data above lookalike digit sequences.
Where it hides
- Spreadsheets and CSV exports
- PDF forms and statements
- Word documents and text files
- Scanned forms (via OCR)
// RESULTS — findings scored by confidence and severity
Why it matters
The risk of leaked bank details
Account and routing numbers enable fraudulent ACH transfers and are a prime target in business-email-compromise scams. They accumulate in payroll files, vendor records, and reimbursement forms.
- Payroll and direct-deposit forms
- Vendor and supplier banking records
- Expense and reimbursement spreadsheets
- Wire-transfer instructions in PDFs and emails
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags bank details 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.
Score
Every finding gets a confidence and severity score, so real bank details rise above coincidental matches.
OCR
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching bank details in screenshots and scans.
Remediate
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 bank details FAQ
How do I find bank account & routing numbers in my files on Windows?
