Employer returns: RTI submissions: NVR: trace and match

The RTI Service will process the NINO Verification Request (NVR) submission through NPS trace and match using the NINO and / or employee data provided.

NPS will then perform Trace and Match through existing process (PAYE120001) to

  • Verify


  • Obtain a National Insurance Number

NPS will then respond to RTI Service accordingly and a message will be sent back to the employer through the online submission route.

Once the tracing routines have been invoked there will be three possible results

  • Single Match
  • Multiple Match
  • No Match

Corresponding messages on successfully matching will be sent to the employer, these messages will be

  • ‘This notification provides the correct NINO. For future submissions please use this NINO instead of the one you are currently using.’
  • ‘The NINO you have provided is incorrect. Please stop using it. We will notify you of the correct NINO as soon as possible.’
  • ‘For future submissions please use the NINO provided in this notification.’
