High-profile celebrities such as Wayne Rooney, Sienna Miller, Sir Paul McCartney and Delia Smith have so far emerged as being potential victims of alleged voicemail interception by the newspapers.
However, The Independent claims that the full list of up to 600 names that prosecutors believe may be involved in phone hacking criminal cases could be revealed "within weeks".
The list is expected to feature more well known public figures allegedly targeted by the News of the World, including politicians, actors, popstars and murder victims.
The move - the biggest single announcement of alleged targets of voicemail interception so far - could place new pressure on Rupert Murdoch's media empire, particularly if there are more names on the list from Hollywood.
So far, prosectors have indicated that Brad Pitt and Angelina Jolie are on the charge sheet, but there could be numerous other US stars that have been targeted.
Murdoch's US-based News Corporation is currently in the process of separating its publishing business, which includes British newspapers such as The Times and The Sun, from its more profitable film and TV assets.
The move is part of attempts to assure investors over News Corp's corporate governance and structure, but the confirmation of more high-profile alleged hacking victims, particularly if they are US stars, could seriously shake confidence in the firm.
Detectives are understood to have already contacted the majority of "likely" victims of hacking, and many have already launched civil cases against the now defunct News of the World.
Police have also been contacting victims as part of their generic phone hacking cases against several former News of the World staff, including Rebekah Brooks, Andy Coulson, Stuart Kuttner, Greg Miskiw, Ian Edmondson, Neville Thurlbeck and James Weatherup.
The Independent says that the full list of names (excluding those who request theirs not be disclosed) will be announced after the police finish their investigation process. It is thought that up to 400 people not previously known to be victims could be identified.
