Area Code 464 – Qitaihe, Heilongjiang

Overview of Area Code +86 464

The telephone country code +86 is assigned to the People's Republic of China under the ITU-T E.164 international numbering plan. Within the national numbering plan, the area code 464 is a geographic National Destination Code (NDC) that routes calls to the city of Qitaihe (七台河) in the eastern part of Heilongjiang Province, in the northeastern region of China. Qitaihe is a prefecture-level city known for its coal mining industry and is situated in the Wanda Mountains, bordering the cities of Jiamusi and Jixi.

Geographic Coverage and Administrative Jurisdiction

The 464 area code serves the entire administrative jurisdiction of Qitaihe City, including its three districts: Taoshan District, Xinxing District, and Qiezihe District, as well as the county-level city of Boli (勃利县). The code is used for all fixed-line (PSTN) telephone services within this region. It is important to note that this is a geographic code, meaning the number is tied to a physical location, and calls to these numbers are routed via the public switched telephone network (PSTN) to the local exchange in Qitaihe.

Dialing Formats and Caller Instructions

For callers within China, dialing a Qitaihe landline requires the trunk prefix 0 followed by the area code and the subscriber number. The local subscriber numbers in Qitaihe are typically 7 digits long, making the complete domestic dialing format: 0 464 XXX XXXX. For example, a local number might be 0 464 123 4567.

For international callers, the format is: +86 464 XXX XXXX (or 011 86 464 XXX XXXX when dialing from the United States or Canada). The leading '0' of the domestic trunk prefix is omitted when dialing from abroad. For instance, to call a Qitaihe landline from outside China, you would dial +86 464 123 4567.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for Qitaihe; the 464 code is the sole geographic area code for the city. However, as with many regions in China, the number of fixed-line subscribers is stable, and the 7-digit subscriber numbering provides sufficient capacity for the local population. It is also worth noting that mobile phone numbers in China are non-geographic and begin with prefixes such as 13x, 14x, 15x, 16x, 17x, 18x, and 19x, and are not affected by area codes. When dialing a Chinese mobile number, you simply dial +86 followed by the 11-digit mobile number, without any area code.

Practical Tips for Callers

• When calling from a landline in another Chinese city, always use the trunk prefix 0 before the area code (e.g., 0 464 ...).
• When calling from a mobile phone within China, the trunk prefix 0 is often optional, but it is safe to include it.
• International callers should replace the leading '0' with the country's international exit code and then dial 86 464 ...
• Ensure you have the correct 7-digit subscriber number; missing digits will result in a failed call.
