Payroll register de-identification is the removal of personal identifiers from a wage register kept under FLSA 29 CFR 516. That rule sets the recordkeeping a firm must hold. anonym.plus marks each name and number on your device, so the totals stay useful while staff data is shielded.
When this applies
A register lists every worker, SSN, and amount in one grid. You trim those identifiers before the file goes to an analyst or external auditor.
How anonym.plus handles it
- Open the register in anonym.plus on your device.
- Local OCR reads a scanned printout if needed.
- The tool flags each name, SSN, and bank line.
- Confirm the flags and keep column totals intact.
- Swap or black out the marked items.
- Save the clean grid locally.
What you need to provide
- The register (CSV, XLSX, PDF, or scan).
- An operator: Replace, Redact, or Mask.
- Optional shared map so one worker maps to one alias.

Limitations & cautions
A small headcount can re-identify a person from role plus amount, even after names go. The tool flags named items. Aggregate small groups yourself before you share the file.
Frequently asked questions
Does FLSA 29 CFR 516 require me to keep the data?
Yes. The rule sets the records a firm must retain. De-identifying a working copy for analysis does not change what you keep on file.
Can I keep one worker steady across rows?
Yes. Turn on the shared map and the same person maps to the same alias everywhere in the grid.
Is the register sent anywhere?
No. The tool is offline. The grid and its staff data stay on your device.
