A Crown Servant may have one or more of the following on the tax credits computer or the system containing Child Benefit information

  • a BFPO address in either customer’s address details
  • ‘Foreign Office’ or ‘Home Office’ in either customer’s work details
  • any mention of ‘Army,’ ‘Navy,’ ‘MOD,’ or ‘HMF’ in either customer’s work details.

A NAFFI worker may have the following on the tax credits computer or the system containing Child Benefit information in either customer’s work details, ‘NAFFI’.
