Received a call or message from +66?
A call or text from +66 (or 0066) originates from Thailand.
If you don't know anyone in Thailand, 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 +66 number unless you have an account in Thailand.
- Spoofed numbers: The caller ID can be faked. A call showing +66 may not actually originate from Thailand.
If you do know someone in Thailand and want to call them back, see the dialing instructions below.
