Validate a [Postal Index Number][wiki] for India with a few regexes and zero false-positives. The regexes are available in `regex.txt`. There is one regex per area code (the first digit of the PIN, which goes from 1-8).
Validate a [Postal Index Number][wiki] for India with a few regexes and zero false-positives. The regexes are available in `regex.txt`. There is one regex per area code (the first digit of the PIN, which goes from 1-8). Available as a package for Ruby, Python, Node.js, and browsers.
## Why?
A simple `\d{6}` approach marks a lot of invalid pincodes as valid. Out of the 900000 possible combinations, only approximately `155600` are valid pincodes in India. A simple example is `111111` which is an invalid pincode, but any simple 6 digit-check will pass it as a valid one.
