Map of the area codes

Telephone numbers in the People's Republic of China are administered according to the Chinese Telephone Code Plan. The structure of telephone numbers for landlines and mobile service is different. Landline telephone numbers have area codes, whereas mobile numbers do not. In major cities, landline numbers consist of a two-digit area code followed by an eight-digit local number. In other places, landline numbers consist of a three-digit area code followed by a seven- or eight-digit local number. Mobile phone numbers consist of eleven digits.

Landline calls within the same area do not require the area code. Calls to other areas require dialing the trunk prefix 0 and the area code.

Calling a mobile phone from a landline requires the addition of the "0" in front of the mobile phone number if they are not in the same area.[citation needed] Mobile to landline calls requires the "0" and the area code if the landline is not within the same place. Mobile to mobile calls does not require the "0" outside mainland China.

The special administrative regions of Hong Kong and Macau and the disputed territories controlled by the Republic of China (Taiwan) and India are not part of this numbering plan and use the country codes 852, 853, 886 and 91 respectively.

Mobile phones

In mainland China, mobile phone numbers have eleven digits in the format 1xx-XXXX-XXXX (except for 140–144, which are 13-digit IoT numbers), in which the first three digits (13x to 19x) designate the mobile phone service provider.

Before GSM, mobile phones had 6-digit (later upgraded to 7-digit) numbers starting with nine. They had the same numbering format as fixed-line telephones. Those numbers were eventually translated into 1390xx9xxx, where xx were local identifiers.

The oldest China Mobile GSM numbers were ten digits long and started with 139 in 1994, the second oldest 138 in 1997, and 137, 136, 135 in 1999. The oldest China Unicom numbers started with 130 in 1995, the second oldest at 131 in 1998. Keeping the same number over time is somewhat associated with the stability and reliability of the owner. The 5th to the seventh digit sometimes relates to age and location.

China's mobile telephone numbers were changed from ten digits to eleven digits, with 0 added after 13x, and thus the HLR code became four-digit long to expand the capacity of the seriously fully crowded numbering plan.

In 2006, 15x numbers were introduced. In late 2008, 18x and 14x (for data plans or IoT) were introduced. In late 2013, 17x were introduced. In 2017, 16x and 19x were introduced.

In December 2016, each cell phone number was required to be consigned to a real name in mainland China.[citation needed]

In November 2010, MIIT has started the trial mobile number portability service in Tianjin and Hainan, in 2012 the trial has extended to Jiangxi, Hubei and Yunan provinces. On 10 November 2019, all provinces started accepting MNP requests for all mobile carriers, except for technical difficulties, the MVNO phones, satellite phones and IoT phones.

As of 2016, all carriers are releasing USIM cards.

Mobile service carriers can be identified by the first three or four digits as follows:

  • For mobile phones:

1nn xxxx xxxx Calls to mobile phones within China

+86 1nn xxxx xxxx Calls to mobiles from outside China

Area 1 – Capital Operation Center

Emergency numbers

From within Mainland China, the following emergency numbers are used:

In most cities, the emergency numbers assist in Mandarin Chinese and English.

Starting from 2012 in Shenzhen, an implemented system upgrade to unify three emergency reporting services into one number, 110. A similar approach is being installed in more cities in China to make them more convenient.

Dialing 112, 911, and 999 (outside Beijing without area code 010) plays a recording message about the correct emergency numbers in Chinese and English twice: "For police, dial 110. To report a fire, dial 119. For ambulance, dial 120. To report a traffic accident, dial 122." on China Mobile and China Unicom phones, NO SERVICES will be redirected. The error messages "Number does not exist" will be played on China Telecom phones, and NO SERVICES will be redirected. However, some local report said that in sometimes, only within Beijing, China Unicom landlines and mobile phones call 010-112 may be successful as reporting service for call failures.

  • 100xx – Telecommunications Customer Service
