Area Code 207 – Tuyen Quang province

Geographic Overview

The +84 207 area code is the National Destination Code (NDC) assigned to the landline telephone network of Tuyen Quang province, a mountainous administrative region in northeastern Vietnam. Tuyen Quang shares borders with Ha Giang, Cao Bang, Bac Kan, Thai Nguyen, and Phu Tho provinces. The province is known for its scenic landscapes, including the Na Hang Nature Reserve, and its administrative center is the city of Tuyen Quang. This area code covers all fixed-line subscribers within the province, including both urban and rural districts.

Dialing Formats

When calling a fixed-line number in Tuyen Quang from within Vietnam, you must use the trunk prefix 0 followed by the area code 207 and the subscriber number. For example, to call a landline in Tuyen Quang, you would dial: 0207 XXX XXXX. The subscriber number is typically 6 to 7 digits long, making the total national significant number (NSN) length 9 to 10 digits (excluding the trunk prefix).

For international callers, the format is: +84 207 XXX XXXX (drop the leading '0' of the trunk prefix). For instance, from the United States, you would dial: 011 84 207 XXX XXXX.

Caller Instructions

Local callers within Tuyen Quang: If you are calling from another fixed-line number within the same area code, you may be able to dial only the subscriber number without the area code, depending on your local exchange. However, for clarity and consistency, it is recommended to always use the full national format 0207 XXX XXXX.

Callers from other provinces in Vietnam: Dial 0207 followed by the subscriber number. Do not omit the trunk prefix '0'.

International callers: Dial your country's exit code (e.g., 00 from many European countries, 011 from the US/Canada), then Vietnam's country code 84, then the area code 207 without the leading '0', and finally the subscriber number.

Regulatory and Technical Notes

The 207 area code is part of Vietnam's national numbering plan, managed by the Vietnam Telecommunications Authority (VNTA) under the Ministry of Information and Communications. It is a geographic code, meaning it is tied to the physical location of the fixed-line service. As of recent years, there have been no overlay plans for this area code, so the 10-digit dialing format (including trunk prefix) is standard for all calls within Vietnam. Fixed-line numbers in Tuyen Quang are primarily served by VNPT (Vietnam Posts and Telecommunications Group), but other licensed fixed-line operators may also provide services in the region.

When dialing from a mobile phone within Vietnam, you must include the area code even if you are physically located in Tuyen Quang, as mobile numbers are non-geographic and require the full national number.
