SSN redaction is the removal of full Social Security numbers from wage records tied to IRC §6051. That section governs the wage statement an employer issues. anonym.plus finds each nine-digit value on your device and masks it to a safe form, so the record stays clear while the number goes.
When this applies
A wage statement repeats the SSN across pages and copies. You must cut each to the last four digits before a copy is shared or archived.
How anonym.plus handles it
- Open the wage record in anonym.plus on your device.
- Local OCR reads scanned statement pages.
- The tool flags every full nine-digit value.
- Apply Mask to keep only the last four digits.
- Confirm no full number remains anywhere.
- Save the clean record locally.
What you need to provide
- The wage statement (PDF, DOCX, or scan).
- The Mask operator set to keep the last four digits.
- Optional batch for many statement pages.

Limitations & cautions
A nine-digit value on a faint scan can confuse OCR. Check the flags on image pages so no full number slips through. The tool masks what it finds; verify the result before you share.
Frequently asked questions
How much of the SSN may stay on a shared copy?
A common practice keeps only the last four digits. anonym.plus uses the Mask operator to keep those four and hide the rest in one pass.
Does it also catch taxpayer ID numbers?
Yes. ITINs and similar taxpayer IDs are flagged alongside the SSN.
Can it read a number printed on a scan?
Yes. Local OCR reads the image, then masks the value. Always verify faint pages.
