Sometimes we cannot even identify which country the missed call is from (except of coursethe ones from our home country and a few others for which we know the international dialing code). Then how do we find it?
Centralized database
There is a centralizeddatabase which has the following details about almost every phone number in the world.
- Type of Number
- Country
- City / State / Exchange location
- Original Network Provider
1. Type of Number
This specifies whether the number is a Mobile number or a Landline/Fixed line referred as Geographic number. There is also a type of number called NonGeographic Number in countries like UK which is not linked to any specific location/city.
2. Country
It is the country the number belongs to.
3. City / State / Exchange location
This gives the city and exchange location information for a fixed line phone and the zone or state for a mobile number.
4. Original Network Provider
This is the actual telecom company providing the service like Airtel, BSNL, Verizon, T-Mobileetc. But network provider listed here may not be the present network/service provider because Number Portability is not taken into account.
How can you use this service?
+
Eg. +12532532533 or +447010752752
For fixed line phones, enter as follows:
+
Eg. +914422102210
where 91 is India’s country code, 44 area code for Chennai and 22102210 being the actualphone number. In India area codes are of varying length but the phone number together with the area code is always 10 digits for Indian numbers.
You can also use 00 instead of + .
