Received a call or message from +84?
A call or text from +84 (or 0084) originates from Vietnam.
If you don't know anyone in Vietnam, be cautious. Common patterns with unfamiliar international numbers:
- One-ring scams (Wangiri): The caller rings once and hangs up, hoping you'll call back a premium-rate number. Don't return calls to numbers you don't recognize.
- SMS phishing: Messages claiming to be from banks, delivery services, or government agencies. Legitimate organizations won't contact you from a +84 number unless you have an account in Vietnam.
- Spoofed numbers: The caller ID can be faked. A call showing +84 may not actually originate from Vietnam.
If you do know someone in Vietnam and want to call them back, see the dialing instructions below.
