Phone app number location

How the Phone app is able to handle from which city a call is coming ?

The phone app does not "handle" where a call is coming in from. What do you mean by "handle"?

As far as I understand, the phone app displays whatever information the "network" sends it.

Local database of phone prefixes I think.

In my Phone app "Recents" section, for some recents calls I can see :

The number
The city or country, and date

In that case, I don't know for sure but probably its just a simple area code look up.

I don't see a reference to a local database of phone prefixes.
I did some research. The Phone app seems to be named Dialer on AOSP :

The Android Telecom framework manages audio and video calls on an Android device.
Screen calls. The spam check need network verification.
But too much information there.

It look more interesting here in the spam section :

void reportSpamFromCallHistory(
      String number,
      String countryIso,
      int callType,
      ReportingLocation.Type from,
      ContactSource.Type contactSourceType);

An input to the discussion from someone more technical would be useful.

People looking at the source code use something better than the search field "Go to file" on Github ?
Don't know if it's a Google limitation but I can't use the search function in https://developer.android.com/
