A bone anchoring device includes an anchoring element having a shank for anchoring in a bone and a head, a receiving part configured to pivotably receive the head, and a pressure member for exerting pressure on the head to clamp the head in the receiving part, the pressure member defining a head receiving recess for pivotably holding at least a portion of the head therein and comprising a first surface configured to restrict removal of the head from the head receiving recess. The head includes a first position indication structure configured to engage a second position indication structure of the bone anchoring device when the shank assumes a first angular position relative to the receiving part. The first and second position indication structures disengage from one another when the shank is moved out of the first angular position to a different angular position.
