I have been searching for free/paid (preferably free) sources for postal code shapefiles for India.

Does anyone know where I can find one?

This is probabaly not the answer you are looking for, but here it is:

You won't find them, since no one (not even the Postal Department) has Authentic Boundaries.

Pin codes in India are a way of indexing Post Offices. Multiple Post Offices can have one pin code, and one Post Office can deliver to Multiple Pincodes.

It's a Myth that there is such a thing as Pin Code boundaries, which form an mutually exclusive, and exhaustive polygon coverage of the country.

Some vendors offer this data for a price, but in my experience, that data is rubbish, and wrong in many areas that I have checked.

    It is really the same in the USA. We just fake Zip Code Polys. They are really actually quite meaningless. Nov 12, 2014 at 3:57
  • @usertwoseventwothreenine: True, but you do get this polygon data from authentic sources in the US, which is not the case in India. Nov 12, 2014 at 3:59

    I suppose Census counts as authentic. Interestingly in the USA many third parties sell the same rubbish data as well. Nov 12, 2014 at 4:00
  • The United States Census Provides Polygons for Zipcodes. check out www.boundaries-io.com

Postal boundaries for most Indian states are at http://postalgis.nic.in/view/

  • Unfortunately they don't appear to be accurate at all. I Checked the boundaries around Tier 3 Cities like Pune & Jodhpur. Apr 17, 2018 at 10:40

    This is worrying, given that the source is official. Do you think that errors are likely to be higher in urban areas where boundaries are more dense? Apr 18, 2018 at 11:08
  • They seem to be accurate in Mumbai & New Delhi; I think they just haven't got around to mapping the Tier-2/Tier-3/Rural areas yet. Apr 19, 2018 at 5:20
  • Thank You! Actually, I am trying to map PIN CODES to Legislative Constituencies. I guess the probability of error in that case will be lower the larger the constituency. Apr 20, 2018 at 6:14
  • Any idea about how can I download these shapefiles? I can't seem to find the link to download the shapefiles.
