Use only evisa.gov.vn for an official Vietnamese e-visa and save the approved PDF offline. Vietnam now also asks foreign air passengers arriving through major international airports to submit the separate, free Pre-arrival Information form at prearrival.immigration.gov.vn and retain its QR code. Cash in Vietnamese đồng remains essential for small restaurants, markets and transport, while foreign cards work more reliably at larger businesses. Ordinary VietQR codes usually require a compatible bank or wallet, so MoMo is not a practical short-stay tourist recommendation. Book airport rides inside Grab or Green SM, verify the plate and ignore people claiming to be app representatives in the arrivals hall. Administrative boundaries changed in 2025, so older and newer versions of an address can coexist. Save the Vietnamese venue name and map pin. Weather and flood risk vary sharply by region; follow official warnings before road, rail, boat or hiking plans. Call 112 for national rescue, 113 for police, 114 for fire and 115 for an ambulance. Emergency operators may speak only Vietnamese.
An optional international wallet that can fund and scan supported Vietnamese merchant QR codes without a local bank account.
An optional travel card and currency account for eligible customers, useful for card spending and exchange rather than VietQR.
