Thai Phone Number Lookup (+66)

Unknown calls from Thailand

Thailand has been hit hard by organised "call-centre gangs" operating from across the border, and many Thais now hesitate before answering an unknown number. These callers impersonate police officers, courier companies, the Revenue Department or electricity authorities, often with convincing scripts and official-sounding hold music. SMS messages carrying links to fake LINE accounts or loan offers add to the pressure. The authorities and mobile operators have tightened SIM registration and blocked many fraudulent links, but suspicious contacts persist. Looking up a number before calling back helps people tell a genuine parcel driver or clinic from a scripted fraud.

Common phone scams in Thailand

Courier and police impersonation

A caller says a parcel in your name contains illegal items, then transfers you to a fake police officer who claims your bank account is under investigation. You are told to move money to a "safe" account for checking. Thai police never ask the public to transfer funds for verification.

Fake government refunds

Messages claiming to come from the Provincial Electricity Authority, Revenue Department or another agency announce a refund and ask you to add a LINE account. You are then guided to install an app that gives remote control of your phone and banking apps. Agencies do not issue refunds through personal LINE chats.

Investment and romance schemes

A friendly contact met on social media or a dating app introduces a trading platform with spectacular returns. Early profits on screen encourage larger deposits, but withdrawals are refused or require extra "fees". The platform is controlled by the scammers and the money cannot be recovered through it.

Report scam calls in Thailand

Call the police Anti Online Scam Operation Center hotline 1441 or file a report at thaipoliceonline.go.th; contact your bank immediately to freeze transfers; complain about telecom misuse to NBTC on 1200.

Stop unwanted calls

Thailand has no national do-not-call register. Block numbers on your phone and use your carrier's spam filtering.

Thailand number lookup FAQ

Who called me from +66?+

+66 is Thailand's country code. Numbers continuing with 6, 8 or 9 are mobiles; a 2 after the code indicates a Bangkok landline. If the caller claims to be police or a courier and mentions your bank account, hang up.

Why does an unknown call show a + sign and a foreign code?+

Scam networks often route calls through overseas or internet lines, and Thai operators may display a warning for international calls. If you are not expecting a call from abroad, treat an unexpected international number claiming to be a Thai agency with suspicion.

What should I do after transferring money to a scammer?+

Contact your bank straight away and call 1441 so police can attempt to freeze the receiving account. Then file a formal report online at thaipoliceonline.go.th. Speed matters, as funds are moved quickly.
