Ethiopian Airlines said in a statement on Monday that two devices the cockpit voice recorder and the digital flight data recorder were recovered from the crash site.
A digital flight data recorder, known as a "black box," records details from an aircraft's sensors. Data from a cockpit voice recorder also offers further clues.
The plane crashed six minutes after takeoff from Addis Ababa for the Kenyan capital of Nairobi on Sunday morning.
In response both China and Indonesia have grounded all Boeing 737 Max 8 planes, the model involved in the crash, in response.
Many of those on board the plane when it crashed were aid workers. Those identified so far come from more than 24 different countries.
The plane was a Boeing 737 Max 8, the same model which had a fatal crash in Indonesia in October.
A 737 Max 8 operated by Lion Air flight crashed into the sea and killed everyone on board.
Both the cockpit voice recorder and the digital flight data recorder were recovered from the crash, and investigations into that crash have yet to reach a final conclusion.
A statement on the Civil Aviation Administration of China (CAAC)'s website said that the decision was partly based on similarities between the Ethiopian Airlines crash and the Lion Air crash.
