The Bosnian Serb government has drawn up a list of 19,473 Serb soldiers who operated in the region of Srebrenica at the time of the massacre there in 1995.
Many victims found in mass graves have been reburied
The secret list, compiled since 2003, includes almost 900 people still thought to be working for the Bosnian Serb government, army or police.
It will be forwarded to the state prosecutor's office for review.
More than 7,000 Muslim men and boys died when Bosnian Serb troops overran the UN-protected enclave in 1995.
The disclosure is part of an ongoing process instigated by the international community to force the Bosnian Serb government to acknowledge and account for the war crimes committed at Srebrenica, the BBC's Matt Prodger says.
Not every single person on it was directly involved in the massacre, our correspondent says.
The list also steers clear of apportioning responsibility onto people involved in the massacre.
But it does include people previously identified as giving orders for the killings and the actual executioners.

Authorities have pledged to investigate the roles of the 892 people who are still understood to be holding official positions in the autonomous Bosnian Serb republic.
The list is also supposed to provide Bosnian prosecutors with a fuller picture of how the crimes were perpetrated.
The head of the Bosnian Serb army at the time, Ratko Mladic, and his civilian counterpart, Radovan Karadzic, have been charged with genocide over Srebrenica.
But they remain fugitives thought to be hiding in Bosnia or neighbouring Serbia and Montenegro.
The massacre in eastern Bosnia is considered the worst single atrocity in Europe since World War II.
