History
China has expanded numbering capacity mainly through additional mobile and service ranges. Official notifications added the 190, 193 and 196 mobile ranges in 2020. The country uses one official standard time, UTC+8.
Area-code coverage follows telephone numbering areas, not necessarily the administrative limits implied by a city name. A mobile prefix does not reliably identify the current operator after portability.
Nearby Area Codes
“Nearby” means related entries in this country directory, not a guarantee of a shared physical border.
