Well, There were postal delivery zones in the past and the postal department even used to make maps of these zones. The Delhi postal delivery zone map <https://drive.google.com/file/d/0B1RcWLku0ZOWWVBHMldrZWdfZEU/view?usp=sharing> had boundaries for delhi. I am not sure if other cities had them or how long the postal department was doing this, but it certainly can help with the boundaries for cities.
