How do I look up a long-distance telephone area code?

Enter a city name or telephone area code to perform a bidirectional lookup. For example, entering a city name returns its corresponding long-distance telephone area code, while entering an area code such as “010” or “021” returns the corresponding city or area.

What is a long-distance telephone area code?

A long-distance telephone area code is a numeric code used by the mainland China landline telephone system to identify different areas. It is generally used when making domestic long-distance calls to landline numbers. Common area codes include Beijing 010, Shanghai 021, Guangzhou 020 and Shenzhen 0755.

What is the difference between telephone area codes and mobile numbers?

Long-distance telephone area codes are mainly used to identify areas for landline phones, while mobile numbers are identified through mobile network number ranges. They are different numbering systems. Telephone area codes are generally associated with cities or areas, while mobile numbers do not use city long-distance area codes as their primary identification method.

Reverse telephone area code lookup

If you only know a landline area code, you can use reverse lookup to find the corresponding city or area. For example, entering 010 can return Beijing, while entering 021 can return Shanghai.

When is reverse area code lookup useful?

• Determine the area associated with a landline area code.
• Check the area code of an unfamiliar landline number.
• Confirm the long-distance area code for a city.
• Look up the area code before making a domestic long-distance landline call.

Telephone area code lookup by province

In addition to searching by city name and area code, you can browse national long-distance telephone area codes by province. Select a province to view its related cities and telephone area codes. This is useful when you are unfamiliar with a city area code.

Quick national area code reference

Area codes organized by province allow you to find cities level by level from the administrative region without memorizing specific area codes. When checking the landline area codes of multiple cities, the province list can also help locate them quickly.

How many digits are telephone area codes?

Mainland China city long-distance telephone area codes do not all have the same length. Common formats include 3 and 4 digits. For example, Beijing 010 and Shanghai 021 use the common 3-digit format, while some cities use 4-digit area codes. Always use the complete area code when searching.

Why do some area codes start with 0?

Domestic long-distance telephone area codes generally start with 0. When making a domestic long-distance call to a landline, the appropriate area code is used according to domestic dialing rules. The actual dialing method may also depend on the telephone line and carrier rules.

Long-distance telephone area code data

The telephone area code data in this tool is organized based on mainland China administrative division information and currently uses the 2023 national administrative division data as its basis. Administrative divisions may change, so historical area names and current area names may differ.

Administrative division changes

Some areas may undergo administrative changes such as converting counties into districts, adjusting county-level cities or changing area names. Telephone area codes are generally relatively stable, so a change in administrative division name does not necessarily mean the telephone area code changes at the same time.

What is the difference between long-distance area code lookup and mobile number location lookup?

Long-distance telephone area code lookup mainly targets area codes for landline telephone numbers, while mobile number location lookup mainly uses mobile number ranges to identify the carrier and number-range location. The two lookup methods target different types of numbers and should not be confused.

Landline telephone area codes

Mainly used to identify the city or area associated with a landline, such as 010 and 021.

Mobile number location

Mainly matches the carrier and number-range location based on the mobile number range, which is different from a landline long-distance area code.
