Answer 2

Indiana is not a country.

The country code for the United States, plus Canada and 18 island nations and territories in or near the Caribbean, is +1.

The country code for India is +91. The country code for Indonesia is +62.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
