Narrative:
I was being relieved off of departure radar north (drn) when aircraft X departed flashing 'dm' (departure message) in the data block. I hurried to finish the relief briefing so I could troubleshoot. When I did; I found aircraft Y inbound to atl. [Airline company] had two aircraft with the same call sign in the air at the same time. We advised our aircraft X he was now going to be aircraft xa and I made the change in eram.I advised the supervisor and asked if he wanted to take care of it or if I should; he said; 'go ahead'. I don't believe he took any action.please share this information with whoever you see fit. [Airline company] should be asked to advise their dispatchers to take greater caution when flight numbers involve different aircraft; especially at their hubs. In this case; it wasn't a huge problem; it created confusion and additional workload; but it is nonetheless unacceptable.
