HM Revenue & Customs (HMRC) will withdraw the CA6855 clerical tracing service on 31 March 2014.
This is following the introduction of reporting PAYE in real time and the National Insurance number verification request service (NVR).
If you are not yet reporting PAYE in real time yet and need to use this service you should do so now.
If you are reporting PAYE in real time but you have not used the NVR service you should read the guidance 'Check an employee's National Insurance number' that can be found in the guide 'Making sure you use the correct National Insurance Number'.
BrightPay includes the NVR request among its list of RTI functions.
