I have been trying since to get this but couldn't,
may be because I didn't know the exact keywords
to use while searching for it.

What I need is; How is the mobile network numbers
are formatted and their names.

Let me use MTN Nigeria ( a mobile network provider in Nigeria)
as example. I will use two of it's number for this example which are;

local = 0-803-5002249 international = +234-803-5002249

local = 0-706-0552680 international = +234-706-0552680

Now on these two numbers, they have "country mobile dial code"
which are "0" for local and "+234" for international.

They have the next 3digits numbers which are "803" and "706" respectively.

And the next 7digits numbers which are "5002249" and "0552680" respectively.

Now my questions are, The first set of numbers, what are they called?
( I called them "country mobile dial code" but am not sure), and what keyword will I use to be knowing the local part of that number for any
country from search engine? like USA is "1" and Nigeria is "0", if I want
to know local mobile dial code for other countries which keyword will I
use to search it?

Secondly, what is the name for the second part of the numbers?
( I thought it might be "Network Identification Number" but am not sure too) and what keyword will I use to be knowing them from search engine? like MTN Nigeria ( a Mobile Network Provider in Nigeria) has numbers like 803, 806, 801, 703 etc on that, what if I want to know that of USA AT&T or others?

Thirdly, do all the Mobile Network Providers in the world have the digits of their last set of number to be 7digits or is there any one longer or shorter than 7digits?

Please somebody help me with these for I have been searching for it but no success, and it might be that am using wrong keywords.

Thanks.
