National Insurance number redaction is the removal of full NI values from wage records tied to the Income Tax (PAYE) Regulations 2003 under RTI. The identifier links a worker to PAYE and benefit accounts. anonym.plus finds each value on your device and masks it to a safe form, so the record stays clear while the data goes.
When this applies
A wage record repeats the NI value across pages and copies. You must hide each one 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 NI value in the standard format.
- Apply Mask to hide the digits, or Replace with a label.
- Confirm no full value remains anywhere.
- Save the clean record locally.
What you need to provide
- The wage record (PDF, DOCX, or scan).
- The Mask operator, or Replace with a steady label.
- Optional batch for many statement pages.

Limitations & cautions
An NI value on a faint scan can confuse OCR. Check the flags on image pages so no full one slips through. The tool masks what it finds; verify the result before you share.
Frequently asked questions
Should I keep any of the NINO on a shared copy?
Usually not. Unlike a card PAN, the NI value is best hidden in full. anonym.plus can Mask the whole thing or Replace it with a steady label in one pass.
Does it recognise the NINO format reliably?
Yes. The tool flags the two-letter, six-digit, one-letter pattern, with or without spaces, then hides each match.
Can it read a value printed on a scan?
Yes. Local OCR reads the image, then masks the digits. Always verify faint pages.
