Overview of Area Code +84 256
Area code 256 is the National Destination Code (NDC) assigned to the province of Binh Dinh in the Socialist Republic of Vietnam. Under the ITU-T E.164 international numbering plan, the full country calling code for Vietnam is +84, so numbers in Binh Dinh are dialed internationally as +84 256 XXX XXXX. Domestically, callers within Vietnam use the trunk prefix 0 before the area code, resulting in the format 0 256 XXX XXXX for calls from other provinces or mobile networks.
Geographic Coverage and Administrative Jurisdiction
Binh Dinh is a coastal province located in the South Central Coast region of Vietnam. Its capital and largest city is Quy Nhon, a major economic and cultural hub. The area code covers all landline telephone exchanges within the province, including districts such as An Nhon, Hoai Nhon, Phu My, and Tuy Phuoc. These are fixed-line services provided by the incumbent operator VNPT and other licensed PSTN carriers.
Dialing Formats and Caller Instructions
- International callers (outside Vietnam): Dial your international access prefix (e.g., 00 or +), then 84, then 256, followed by the 7-digit local subscriber number. Example: +84 256 123 4567.
- Domestic callers from another province or mobile phone: Dial 0, then 256, then the 7-digit number. Example: 0 256 123 4567.
- Local callers within Binh Dinh: In most cases, you can dial the 7-digit subscriber number directly without the area code. However, some multi-exchange areas may require the full 10-digit format (including the trunk prefix) depending on local dialing procedures.
Numbering Structure and Overlays
Subscriber numbers in Binh Dinh are 7 digits long, making the complete domestic format 0-256-XXX-XXXX (10 digits including the trunk prefix). As of the latest ITU-T recommendations, no overlay codes have been introduced for this area; the 256 code remains the sole geographic identifier for Binh Dinh. The province's numbering resources are administered by the Vietnam Telecommunications Authority (VNTA) under the Ministry of Information and Communications.
Practical Considerations
When calling from abroad, be mindful of time zone differences (Vietnam is UTC+7). Also, note that while mobile numbers in Vietnam use separate non-geographic prefixes (e.g., 090, 091, 096), landline numbers under 256 are fixed to the Binh Dinh geography. For VoIP services, the same dialing rules apply, but ensure your provider supports international dialing to Vietnam.
