+91 is the international calling code of India. Below is how a phone number with this code is written, at home and from abroad.
International format: +91 8XXXX XXXXX
National format: 08XXXX XXXXX
Inside India a number starts with the trunk prefix 0; drop it after +91.
Mobile number length: 10 digits after +91
From another country, dial + (or your exit code: 00 in most of the world, 011 from North America), then 91, then the national number without its trunk prefix.
+91 belongs to India.
Dial +91 and then the national number without the trunk prefix 0: 08XXXX XXXXX becomes +91 8XXXX XXXXX.
Not here, and not from the code: a code names the country, not the person. This site does not look up the owners of numbers.
