OPREC Customer Accounting Records

Customer accounting records on OPREC are organised alphabetically and divided into 60 databases. Only one user at a time is allowed update access to a database although others can have view access.

An OPREC record consists of three basic screens

  • the first holds details of the customer, partner and appointee
  • the second provides details of the overpayment
  • the third is the recovery screen.

A record can be accessed in several ways. The easiest way to open a record is to enter the Child Benefit Number. A trace can also be made on the NINO, and other traces can be performed using the customer name or overpayment reference number.

Note: when tracing on the name the customers date of birth, surname, initial or forename is required.

A search can also be made using partner details if these have been previously input into the system.

Record Retention
