A Home Office spokeswoman said, "The Criminal Records Bureau will go live in March for organisations with current access to police checks."
The system's reliance on data from the Police National Computer (PNC) has led to postponements for the bureau, which was scheduled to go live in July 2001.
The Commons home affairs select committee last year found that up to two-thirds of PNC data contained errors. It received evidence that the error rate varied between forces from 15% to 65%.
The bureau has received the go-ahead despite ongoing work to improve PNC data.
The spokeswoman said, "We are aware of concerns with the PNC data but we are still working to rectify them."
The bureau, which was developed by ITservices firm Capita, is designed to let employers check potential job applicants by providing wider access to criminal record information.
