# india-pincode-regex Validate a [Postal Index Number][wiki] for India with a regex. The regexes are available in `regex.txt`. There are 2 regexes. The first validates PINs starting from 1-4, and the second validates the ones starting from 5-8. The reason for the split is to keep the regex size small. Currently they are both at 16K each. ## Source The source for the data is the ["All India Pincode Directory"](https://data.gov.in/resources/all-india-pincode-directory) dataset on data.gov.in. ## Usage The `regex.txt` file is 32KB in size, so you can easily use it wherever you want, including browsers. ## License Licensed under the [MIT License](https://nemo.mit-license.org/).
