Mangalore, Sep. 06: All mobile numbers used in our country start with +91. Have you ever wondered why it starts with 91? There are reasons for that.
Calling from a number with +91 can indicate that you are from India. In fact, +91 is the country code of India. The International Telecommunication Union (ITU), an affiliate of the United Nations, assigns this code to every country in the world.
The International Telecommunication Union divides the world into nine zones. These 9 zones include South, Central, West and Middle East Asia.
The calling codes of all the countries in these 9 zones start with +9. For example, India has +91, Pakistan +92. The International Telecommunication Union considers population, communities and many other factors before assigning a country code to a country.
Therefore, the Indian government occasionally makes announcements that it is better not to answer phone calls from unknown numbers. They may be fraudulent calls.
