Thats a list of 3 companys in a building that have acquired other companys. ICOA acquired Idock-USA and Auth Direct back in 2004 of course they are going to have the same address http://www.alacrastore.com/mergers-acquisitions/ICOA_Inc-2512620 The other 2 are an energy group and investigative group, not that strange that 3 businesses would share the same address
