Narrative:
After checking in with approach; I heard and read back cleared to descend to 2;000 [feet]. The pilot flying also heard 2;000 [feet] and set 2;000 [feet] in the altitude alerter. Passing through approximately 5;500 feet; ATC said your assigned altitude is 6;000 [feet]. After the pilot flying was slow to react; I disengaged the autopilot and leveled the aircraft at 5;000 [feet] and started to climb back to 6;000 [feet]. ATC then assigned 5;000 [feet] and gave us vectors.both pilots hearing the wrong altitude; or the controller [made a] mistake of giving the wrong altitude. Passing through approximately 10;000 [feet]; I thought that 2;000 feet sounded a little low for our area. But I dismissed it because I was sure I heard it. Also 2;000 feet is usually the altitude given for the visual approach; so in that sense it sounded normal. At my first second thought; I should have asked the controller for the altitude again.
