Can you know the specific location of the first few 8727 telephones in Beijing?

The first few digits of the phone number can't determine the region or specific location, because there will be many phone number segments starting with the same number in the same region or city. For example, in Beijing, the top digits of 8727 may be Haidian District, Xicheng District, Dongcheng District and Fengtai District. To know the specific location, you need to check the complete phone number and address information.
