VN — Vietnam

Vietnam is a Southeast Asian country on the eastern Indochinese Peninsula with a long coastline along the South China Sea. Hanoi is the capital, while Ho Chi Minh City (Saigon) is the largest city and economic center. Vietnam is one of the fastest-growing economies in Asia and a major manufacturing and tech hub. The Vietnamese Đồng (VND) uses the ₫ symbol and operates with very large numbers — a coffee might cost 50,000₫. For developers, the VN country code maps to the vi-VN locale for Vietnamese. The .vn domain and +84 calling code serve Vietnam. Vietnamese uses the Latin alphabet with extensive diacritical marks (six tones marked by diacritics), requiring full Unicode support. The VND has no subdivision and everyday prices are in thousands or millions, requiring proper large-number formatting. Vietnam's tech ecosystem is booming, with companies like VNG and VinGroup's tech divisions. Mobile payments via MoMo, ZaloPay, and VietQR are widely adopted. Vietnam's young, tech-savvy population and manufacturing-to-tech transition make it one of Asia's most important emerging digital markets.
