Area Code 219 – Ha Giang province

Overview of Area Code 219 (Ha Giang Province, Vietnam)

Area code 219 is the National Destination Code (NDC) assigned to the landline telephone network of Ha Giang province, a mountainous administrative region in the Northeast of Vietnam. This code is part of the Vietnamese national numbering plan, which follows ITU-T E.164 recommendations. When dialing a fixed-line subscriber in Ha Giang from within Vietnam, the trunk prefix 0 is used before the area code, resulting in the national significant number format 0 219 XXX XXXX. From abroad, callers must replace the leading zero with Vietnam's country code +84, yielding the international format +84 219 XXX XXXX.

Geographic Coverage and Administrative Jurisdiction

Ha Giang province shares its northern border with China and is known for its rugged terrain and ethnic diversity. The area code 219 serves the entire province, including its capital city, Ha Giang City, and all districts such as Dong Van, Meo Vac, Yen Minh, Quan Ba, and Vi Xuyen. The province is a popular destination for tourism, particularly the Dong Van Karst Plateau Geopark, which attracts both domestic and international visitors.

Dialing Procedures and Number Format

Local calls within Ha Giang (i.e., between two subscribers in the same province) can be made using the subscriber number alone, without the area code, if the local network supports this. However, for calls from other provinces or mobile networks, the full national format 0 219 XXX XXXX is required. The subscriber number length is typically 7 digits, but some older lines may have fewer digits; always verify the complete number with the subscriber or service provider.

Overlay and Numbering Considerations

Currently, there is no overlay code for Ha Giang; area code 219 is exclusively used for fixed-line services in the province. Mobile numbers in Vietnam are assigned separate non-geographic prefixes (e.g., 03x, 05x, 07x, 08x, 09x) and are not affected by this area code. If you are calling a Vietnamese mobile number, you must use the mobile prefix and not the geographic area code.

Instructions for Callers

• Domestic callers (from other provinces): Dial 0 219 XXX XXXX.
• International callers: Dial your country's exit code, then 84 219 XXX XXXX (omit the leading zero). For example, from the US/Canada, dial 011 84 219 XXX XXXX; from the UK, dial 00 84 219 XXX XXXX.
• Local callers within Ha Giang: Some networks allow dialing only the 7-digit subscriber number, but using the full national format is always safe.

Always confirm the exact number of digits with the party you are calling, as the Vietnamese numbering plan may undergo changes. For the most current information, consult official sources from the Vietnam Telecommunications Authority.
