Frequently asked questions
Will it detect SSNs without dashes (xxxxxxxxx format)?+
Yes — both hyphenated (xxx-xx-xxxx) and un-hyphenated (xxxxxxxxx) SSN formats are detected.
Does this meet HIPAA safe harbour de-identification standards?+
SSN redaction is one of the 18 identifiers required for HIPAA safe harbour. Run a full PII scan to redact all other identifiers as required.
What if an SSN appears in a scanned image within the PDF?+
Run OCR first to create a text layer, then redact. Scanned images without a text layer cannot be automatically detected.
