📍 Geographic Location of Dazhou, Sichuan
Geographic Overview
The +86 818 area code is a geographic National Destination Code (NDC) assigned to Dazhou, a prefecture-level city in the northeastern part of Sichuan Province, China. Dazhou is a significant regional hub with a population exceeding 5 million, comprising several districts and counties, including Tongchuan District, Dachuan District, Xuanhan County, Kaijiang County, and Qu County. The area code covers the entire administrative jurisdiction of Dazhou, including urban and rural areas.
Dialing Formats
For domestic callers within China, the local dialing format is 0818-XXXXXXX (where X denotes the 7-digit local subscriber number). When calling from outside China, the international format is +86 818 XXXXXXX (or 0086 818 XXXXXXX when using the international prefix). Note that the leading '0' of the domestic trunk prefix is omitted in international dialing.
Calling Instructions
- Local callers (within Dazhou): If you are physically located within the Dazhou area code region, you may dial the 7-digit local number directly without the area code. However, due to the implementation of 10-digit dialing in many Chinese cities, always verify with your local service provider. In most cases, local calls within the same area code do not require the area code.
- Domestic long-distance callers (from other parts of China): Dial 0818 followed by the 7-digit subscriber number. For example, to reach a landline in Dazhou, you would dial 0818-XXXXXXX.
- International callers (from outside China): Dial your country's international access code (e.g., 011 in the US, 00 in most European countries), then China's country code 86, then the area code 818 (without the leading 0), and finally the 7-digit local number. For example, from the US, you would dial: 011 86 818 XXXXXXX.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 national numbering plan updates, Dazhou does not have an overlay code; 818 remains the sole geographic area code for the region. The subscriber numbers are 7 digits long, and the total length of a national significant number (NSN) is 11 digits (including the leading 0 for domestic dialing). This structure is consistent across China's geographic area codes, which typically have 7 or 8-digit local numbers. For international callers, the NSN is 10 digits (818 + 7-digit number) when preceded by +86.
Practical Examples
Suppose a local number in Dazhou is 2345678. To call this number from abroad, you would dial +86 818 2345678. If you are in Beijing and wish to call this number, you would dial 0818 2345678. Always ensure you have the correct number of digits; missing a digit may result in a failed call or misrouting.
