Reading a +84 number

• •Mobile if the digits after +84 start with 1, 3, 5, 7, 8 or 9 (+84 91X XXX XXX).
• •Landlines start with an area code, for example +84 210 XXXX XXX for Phu Tho province.
• •Premium rate if it starts with 19 after +84: never call these back.
• •Local time: 1:01 AM in Hanoi right now, an unusual hour for a genuine call.

• •Don't call back a number you don't recognize. One-ring scams hang up after a ring or two so you return the call, which can add a per-minute charge on top of an international rate.
• •Caller ID can be faked. The code shown is not proof of where the caller really is.
• •Real callers leave a message. If it matters, they'll text, email or leave a voicemail. Otherwise, block the number.
