Missed Call From +66?
Unrecognized international numbers are a common pattern in Wangiri ("one ring") scams: the caller hangs up after one ring hoping you call back a premium-rate number. If you don't know anyone in Thailand, don't call back. If the call matters, the caller will try again or leave a message.
Frequently Asked Questions
Which country has calling code +66?
Thailand.
How do I call +66 from the US?
Dial 011 66 followed by the national number without its leading zero.
What does 0066 mean?
0066 is +66 written with the international prefix used in the UK, most of Europe and much of the world: 00 replaces the plus sign, so 0066 and +66 reach the same number in Thailand. From the US and Canada the prefix is 011, so the same code is written 011 66.
Is a call from +66 a scam?
Not necessarily, but treat unexpected international calls with caution. One-ring missed calls are the classic Wangiri callback scam: hoping you return the call to a premium-rate number. If you do not know anyone in Thailand, do not call back, and never share personal or payment details on calls you did not initiate.
