plus 84 country code Page 521

+84 is the country code for Vietnam. From Australia, dial +84, drop any leading 0 from the local number, then the rest—e.g., +84 28 xxx xxxx for Ho Chi Minh City, or +84 9x xxx xxxx for mobiles. On a landline, use 0011 84 instead of the + if your phone refuses to play nice. Texts and apps like WhatsApp are happy with +84 too. If an unknown +84 rings at 3am, it’s either your mate in Hanoi or a scammer with delusions of grandeur—act accordingly.
