Comment rédacter des informations de passeport

Les scans de passeport sont des PDF riches en images avec une zone lisible par machine (MRZ)—deux lignes en bas encodant numéro de passeport, nationalité, date de naissance, sexe, expiration et nom dans un format que tout OCR lit en secondes. Rédacter le numéro visuel tout en laissant la MRZ intacte est l'échec le plus courant dans les dossiers d'immigration et RH. Essayez le modèle Document d'identité en ligne sur un scan de passeport pour capturer numéros d'ID et champs de date de naissance. Développe comment rédacter des documents d'identité avec la structure MRZ spécifique au passeport et la vérification burn-in de comment rédacter un PDF scanné.

What people search for
  • How do I redact a passport scan PDF before sending to employer?
  • Do I need to redact the MRZ lines at the bottom of my passport?
  • Can I share a passport copy with visa stamps redacted?
  • Is cropping my passport scan enough for privacy?
  • What fields stay visible for proof of citizenship vs. full ID?

MRZ structure (both lines must go)

The MRZ uses two lines of OCR-B characters with chevrons (<) as fillers. Line 1 encodes document type, issuing country, and name. Line 2 encodes passport number, nationality, date of birth, sex, expiry date, and optional personal number. Redacting the large visual number on the data page without redacting the entire MRZ band leaves fully extractable identity data.

ZoneContentRedaction default
Photo page visual fieldsNumber, name, DOB, nationalityRedact number, photo, signature unless required
MRZ band (bottom ~10mm)Encoded duplicate of key fieldsAlways redact full band both lines
Visa / entry stampsTravel historyRedact if not required for application
Emergency contact pageContact PIIRedact unless form requires
Search MRZ patterns after export

Run Find for passport number and for MRZ-style strings with multiple < characters. OCR on scans will read MRZ even when the visual number is blacked out with shapes.

Passport scans: the MRZ band at the bottom encodes the same data as the visual fields—redact the full width of both lines.

Use cases: HR, immigration, landlord

RecipientOften requiredUsually redact
US employer I-9In-person inspection of original—follow USCIS rulesDo not substitute redacted scan unless HR instructs
Visa / immigration attorneySpecific pages per checklistMRZ, photo, unrelated stamps per counsel
Landlord (non-standard)Rarely full passport—often utility bill + IDFull MRZ, photo, number if ID requested
Anonymized sampleNothing identifiableEverything except maybe country of issue

Cropping vs. burn-in redaction

Cropping viewport does not guarantee the full scan image is removed from the PDF object stream. True redaction or verified burn-in on the image layer replaces pixels in the MRZ and photo regions. Phone photos saved as PDF need area redaction on the entire data page—see our scanned PDF guide for image-only verification.

Offline workflow

  1. Scan at 300 DPI or export from passport app—avoid glare and skew.
  2. Save passport-original.pdf offline.
  3. Draw region over entire MRZ band (both lines, full width).
  4. Redact photo, visual passport number, signature as scope requires.
  5. Redact visa stamps not needed for submission.
  6. Apply burn-in redaction on image layer.
  7. Verify: MRZ regex search empty; pdfimages spot-check; visual zoom.
  8. Send via encrypted portal only.

FAQ

Is passport number always nine digits?

Format varies by country—redact full MRZ regardless of visual number length.

Can I show expiry date only?

Only if recipient requires it and MRZ is still fully redacted—MRZ contains expiry and must not remain readable.

How is this different from redact-id-document?

Driver licenses use PDF417 barcodes; passports use MRZ—both need encoded zones redacted, not just visible numbers.
