Hello,
It is not an acronym, hence does not have an official full form. India is the name of the country derived from the River Indus, known as Sindhu in Sanskrit. In history, the region was called "India" by Greeks and other ancient civilizations surrounding the river.
For more historical background and origins of names, see related educational resources or encyclopedias. If you were looking for a more creative or unofficial abbreviation for "India," let me know!
