Digital Habits and Channels in Vietnam
Vietnam has high smartphone use, and Zalo is the leading local messaging app, used alongside Facebook and Messenger; Zalo Official Accounts are a common way for businesses to send updates. Advertising SMS must follow Decree 91/2020 on spam, which requires consent, sender identification and restricted sending hours, and branded sender names (brandname SMS) are registered with the operators.
Bank transfers by VietQR, MoMo and ZaloPay are widely used, and cash on delivery remains common. Tet (Lunar New Year) is the biggest commercial period, followed by the 11.11 and 12.12 online sales and Mid-Autumn Festival. Vietnam's Personal Data Protection Law took effect on 1 January 2026.
Vietnam's economy has grown fast through electronics manufacturing (Samsung is the largest foreign investor), textiles, footwear, coffee, rice and seafood. VAT is 10%, temporarily reduced to 8% on many goods. Zalo is the main local messaging app, and MoMo and bank QR codes are used for payments.
