Chinese area code decoded: A thorough guide to China’s telephone area codes
What is a Chinese area code?
Chinese area code structure: how it fits into the broader dialing system
Common Chinese area codes for major cities
- Beijing: 010 (domestic) → +86 10 (international)
- Shanghai: 021 (domestic) → +86 21 (international)
- Guangzhou: 020 (domestic) → +86 20 (international)
- Shenzhen: 755 (domestic) → +86 755 (international)
- Chongqing: 023 (domestic) → +86 23 (international)
- Chengdu: 028 (domestic) → +86 28 (international)
- Tianjin: 022 (domestic) → +86 22 (international)
- Wuhan: 027 (domestic) → +86 27 (international)
- Nanjing: 025 (domestic) → +86 25 (international)
- Hangzhou: 0571 (domestic) → +86 571 (international)
- Xi’an: 029 (domestic) → +86 29 (international)
- Qingdao: 0532 (domestic) → +86 532 (international)
- Qingdao region note: some surrounding areas use 0533, 0536 for specific districts; domestic calls show the appropriate 0-prefixed code (e.g., 0532) before the subscriber number.
These examples illustrate a general pattern: larger cities often use 2- or 3-digit codes (after removing the 0 for international calls), while some provincial capitals and regional centres employ slightly longer codes. The exact digits can vary, especially in prefecture-level cities or rapidly expanding metro areas where new exchanges have been introduced. Always verify the correct area code for a specific district if you are dialling a number that is not clearly tied to a major city.

How to find the correct Chinese area code
Finding the right Chinese area code is straightforward with several trusted methods. Use a combination of official sources, reputable telephone directories, and modern online tools to verify the precise code for any given location. Here are some practical approaches:
- Official telecoms operator resources: The major Chinese operators publish area code information for regional exchanges and customer service pages.
- National or municipal government portals: These sites often provide up-to-date information on administrative divisions and contact numbers.
- Telephone directories and business directories: Printed or digital directories commonly list city codes alongside numbers.
- Online dialling tools and maps: Reputable websites allow you to input a city or district and retrieve the correct area code, including any changes due to administrative adjustments.
When in doubt, confirm the area code by calling a local friend or business partner and asking for the exact digits in the format they use locally. A quick cross-check helps prevent misdialled calls and ensures reliability, especially if you are contacting a new region or a newly converted area.

Practical tips for travellers and businesses
- Always confirm whether you should include or omit the leading 0 when dialling from outside China. The international format is your friend: +86 followed by the area code without the leading 0, then the subscriber number.
- Store numbers in your contacts with both international and domestic formats if possible. This makes it easy to dial correctly no matter where you are calling from.
- Be aware of urban growth: rapidly expanding cities may have updated codes or newly assigned area codes for new districts. When in doubt, verify the exact digits before saving a contact or placing an urgent call.
- For business dialling, consider including the city name alongside the number in your contact records. This helps avoid confusion when dealing with multiple city codes in the same region.
- Remember that some prefecture-level cities use longer area codes that include additional digits for district-level exchanges. If you are uncertain, a quick online search or a phone call to a local assistance line can clarify.

Dialling etiquette and localisation considerations
In addition to correct digits, consider adopting a degree of localisation when presenting Chinese numbers to local partners. Having a correctly formatted number with appropriate spacing (for example, 010-6123 4567 for Beijing) can speed up connection and reduce errors in business communications. Some contacts may also provide alternative numbers for mobile, secondary lines, or VOIP connections. When you encounter multiple numbers, prioritise the landline prefix that aligns with the city’s area code to ensure the most reliable dialling path.
Bringing it all together: mastering the Chinese area code landscape
Checklist for quick reference
- Identify the correct area code for the city or district you wish to contact.
- Remember the domestic long-distance dialling convention: dial 0 before the area code when calling within China.
- When calling from outside China, dial the country code +86, drop the leading 0, and use the remaining area code digits plus the subscriber number.
- Verify codes for new districts or administrative changes that may affect the area code you use.
- Keep a bilingual note of numbers where possible to aid international correspondence and domestic calls.
