I don't know many details about the problem, but I might suspect there's also a "perfect is the enemy of good" issue here; there are serious consequences for getting a 911 call precisely wrong, so it's better to be approximately correct and let humans do the work of narrowing-down. With a pizza delivery, if they drive up to 1234 Somewhere Lane and knock on the door asking for 1236 Somewhere Lane, someone's going to point out the problem (and if not, the cost is relatively low), so it's okay to be precisely incorrect.
