About this tool
The SSN Extractor is a small data-loss-prevention check: it finds 9-digit sequences in the 3-2-4 layout with the structural rules of real Social Security Numbers, so you can audit files for exposed personal data. Because it runs in your browser, the sensitive text is never uploaded.

Frequently asked questions
Is every match a real SSN?
No. The pattern follows the SSA format rules (no 000, 666 or 9xx area, no 00 group, no 0000 serial) but any number with that shape matches. Treat results as candidates.
Why would I scan for SSNs?
To check documents, logs and database dumps for personal data before sharing or publishing them, and to find what needs redacting.
Are my files or data uploaded?
No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
