Is it possible to get information about the city by mobile number. phone?

Question

Database

There is a base - https://www.rossvyaz.ru/activity/num_resurs/regist...
There we are interested in DEF-9x codes. That is, mob. numbers
The fact is that there are only regions ..
Is it possible to find out exactly the city itself?
