Narrative:

Air taxi X was in my airspace after departing bkl climbing to 6;000 ft. Mansfield approach called with a manual hand off on [air taxi Y] an inbound to bkl also with the callsign. This caused difficulty starting a track on the inbound; and communicating with both aircraft even after explaining to both pilots of the duplicate call signs. This has the potential to be a very dangerous situation. There is absolutely no reason a company should have the same call sign on 2 active flights at the same time; given the infinite number of possible flight numbers.
