There weren't "countless" border crossings between East and West. The checkpoints Alpha, Bravo and Charlie were the designated checkpoints for use by allied forces personnel (there were others which only West Berlin citizens could use).
Alpha and Bravo are less famous because Alpha was the main crossing for the "inner German border" dividing East and West Germany proper, while Bravo was in the south-west of Berlin. Alpha and Bravo were used for transiting between West Germany and West Berlin (crossing East German territory but nothing to do with East Berlin). So these crossing points were rather mundane compared to Charlie which was in the heart of the city and was used to transit between East and West Berlin.

The last known escape at a crossing point was actually at this checkpoint on the 18th August 1989. 2 persons hid inside the trunk of an Allied vehicle.
There was also specific crossing points where only West Germans could cross over.
Bahnhof FriedrichstraΓe could be used by all, other than Allied personel.
Allied personel were only allowed to use Checkpoint Charlie.
When not staying overnight, you were required to use the same crossing when leaving.
