๐ป๐ณQuick Facts
Understanding Vietnam's +84 Country Code
+84 is the country code for Vietnam. Any number starting with +84 or 0084 is Vietnamese: mobiles look like +84 9X XXX XXXX (9 digits after 84) and landlines like +84 24 XXXX XXXX for Hanoi or +84 28 XXXX XXXX for Ho Chi Minh City. Vietnam, with a population of over 101 million people, is one of Southeast Asia's fastest-growing economies.
With major cities like Ho Chi Minh City (Saigon, about 14 million since its 2025 merger with Binh Duong and Ba Ria-Vung Tau), Hanoi (the capital, 8+ million), and Da Nang (emerging tech hub), Vietnam has a rapidly modernizing telecommunications sector with near-universal mobile coverage.
Important: When dialing Vietnam, always drop the leading 0 from Vietnamese numbers. Mobile numbers like 096-XXX-XXXX become +84-96-XXX-XXXX internationally.

Ho Chi Minh City (Saigon) - Vietnam's largest city and economic powerhouse, home to about 14 million people and the iconic Bitexco Financial Tower.
๐ฑHow to Dial Vietnam
๐๏ธVietnamese Area Codes
Vietnamese landlines use area codes for different cities: Hanoi is 024 (+84 24) and Ho Chi Minh City is 028 (+84 28). Area codes changed in 2017 - make sure you have updated numbers. When Vietnam merged its 63 provinces into 34 in July 2025, no numbers were cut off: merged provinces keep using their old area codes side by side until the Ministry of Science and Technology announces otherwise, so the codes below still connect.
๐กVietnamese Mobile Carriers
Vietnam has over 130 million mobile subscriptions. Three major carriers (Viettel, Vinaphone, Mobifone) control ~95% of the market. Smaller networks include Gmobile (059, 099), iTel (087) and Wintel (055). Because subscribers can keep their number when they switch networks, the prefix shows the original carrier, not always the current one.
๐Vietnam's Digital Landscape
Zalo Dominance
Unlike most countries, Vietnam uses Zalo (local app) as the primary messaging platform with nearly 80 million monthly users. It's essential for business and personal communication.
Tech Hub Growth
Vietnam is emerging as a major tech outsourcing destination. Da Nang and HCMC host growing startup ecosystems with companies like VNG, Tiki, and FPT.
Vietnamese Diaspora
Around 6 million Vietnamese live abroad, with the largest communities in the USA (about 2.3 million), France, Australia, and Canada. International calling is essential.
Mobile-First Economy
More than 90% of Vietnam's mobile internet subscribers use smartphones. Mobile payments through MoMo, ZaloPay, and VNPay are rapidly replacing cash transactions.
๐ฌCommunication in Vietnam
Zalo is King (Not WhatsApp!)
Unlike most of Asia, Zalo dominates Vietnam with nearly 80 million monthly users. WhatsApp is far less common. If you're calling Vietnamese contacts, ask for their Zalo ID - it's the local standard for messaging and voice/video calls.
๐Best Time to Call Vietnam
Vietnam uses Indochina Time (ICT), which is UTC+7 year-round. Vietnam does not observe daylight saving time, so the gap changes when your clock does: the times below are for US and UK winter time; subtract one hour from the gap during daylight saving or British Summer Time.
Best calling times from US East Coast: 7-10 PM EST (7-10 AM Vietnam) or 6-9 AM EST (6-9 PM Vietnam) - catch people at start or end of their day.
