India PIN Code Lookup: Post Offices, District and State for a PIN Code

postalpincode/pincode-lookup

Looks up an Indian six-digit PIN code and returns every post office that uses it: office name, branch type (head, sub or branch office), whether the office does delivery, and its circle, division, region, district and state. Useful for validating a PIN code and filling a district and state from it on an address form. A PIN code that does not exist returns a validation error rather than an empty list. Data collected by the publisher from India Post and possibly not fully current; passed through unmodified and served by Eden Engine; not an official India Post product.
