## What is an IBAN?

An International Bank Account Number (IBAN, ISO 13616) is a structured identifier of up to 34 characters that uniquely identifies a bank account. Leaking an IBAN exposes the account holder to fraud, social engineering, and (in some jurisdictions) regulatory reporting obligations.

## When to redact bank details

Always redact IBANs, account numbers, and SWIFT codes when sharing financial documents with parties who do not need them to process a payment.

- Audit packets and tax submissions
- Court filings containing financial statements
- Real-estate transaction packs shared with brokers
- Invoices archived for compliance retention

## Format validation, not just pattern matching

Our detector validates the IBAN check digits (modulo-97) and country code structure before flagging a match. This eliminates false positives on similar-looking strings (account references, invoice numbers).

## How it works

1. **Upload the documents** — Invoices, bank statements, contracts. Scanned formats work via OCR.
2. **Enable IBAN detection** — In the PII categories, select "IBAN" alongside any other categories you need.
3. **Quick Studio review** — Detections are visualized over the document. Add manual masks for partial / hand-written references.
4. **Download the masked PDF** — IBANs are physically removed — no recovery from copy-paste or PDF parsing.

## For accounting and fiduciary firms

When sharing client files with auditors or regulators, redact IBAN and account numbers in seconds — even across hundreds of invoices in one batch.

## Frequently asked questions

### Does it validate the IBAN before redacting?

Yes. Detected strings are validated against the ISO 13616 structure to avoid false positives on similar-looking codes.

### Does it redact SWIFT/BIC codes too?

When SWIFT/BIC codes appear alongside an IBAN context, they are typically detected. For standalone codes, add them to "Always Redact" terms.

### Can I keep my own company IBAN visible?

Yes — add it to your "Excluded Terms" and it will never be auto-redacted.
