ACH Payment Record Redaction with anonym.plus

Finance Solution · Payments & Cards · Nacha Operating Rules

ACH payment record redaction is the removal of personal bank data from a transfer entry under the Nacha Operating Rules. Those rules govern how account data in an ACH entry is protected. anonym.plus marks each value on your device, so the entry stays auditable while data is shielded.

When this applies

A transfer entry carries the payer's routing and account numbers in plain digits. You strip those under the Nacha rules before the record leaves your team.

How anonym.plus handles it

1. Open the transfer entry in anonym.plus on your device.
2. The tool flags routing, account, and name fields.
3. Local OCR reads a scanned authorization form.
4. Keep the trace number and effective date you cite.
5. Apply Mask to keep only the last four digits.
6. Save the clean entry locally.

What you need to provide

• The transfer entry or NACHA file (TXT, CSV, scan).
• The Mask operator set to keep the last four digits.
• Optional allow-list for trace numbers.

PII & financial identifiers detected

Compliance achieved

Limitations & cautions

A NACHA file packs fixed-width fields, so a custom layout may need a careful review. The tool flags known fields; verify an unusual format before you share it.
