About Thailand Phone Numbers
Thailand uses the international dialling code +66. When dialling a number from abroad, prefix it with this country code after dropping the local trunk prefix (usually a leading zero).
Example format: a typical Thailand mobile number looks like +66812345678.
Our free lookup tool identifies the caller name and operator when available. It does not expose private information such as addresses or national IDs — our goal is to help you quickly decide whether to answer or return an unknown call.
Developer API
The browser tool signs every Thailand lookup request automatically with a short-lived token and anti-replay signature. For direct integrations, first call /api/client-token, then send the token, timestamp, fingerprint and signature with your lookup request.
GET /api/lookup-international?dialCode=66&countryIso=TH&number=812345678&token=...&ts=...&fp=...&sig=...You can also use an E.164 number when building server tools, but shared country codes like +1 should include countryIso to avoid United States/Canada ambiguity.
