This Arduino library encodes GPS coordinates into India Post's DigiPIN format (10-character code).

#include <DigiPIN.h>

void setup() {
  Serial.begin(9600);
  Serial.println(DigiPIN::getDigiPin(8.5434657, 76.9031381));
}

Clone this repository or download the ZIP.

Copy the DigiPIN folder into your Arduino/libraries/ folder.

Open Arduino IDE and run the example under File > Examples > DigiPIN > ConvertGPS.
