Data source and methodology
SiamDir.net provides a structured directory to help users discover Thai company registration and business information more easily.
Data source
The company and business information presented on SiamDir.net is based on public data from data.go.th, Thailand’s government open data platform. SiamDir.net does not replace the official source and does not represent the government agency that publishes the data.
Update schedule
Our data is updated monthly. The availability and freshness of a record may therefore vary depending on when the source data was published or made available for processing.
How information is organized
To make the directory easier to browse, we organize available records using information such as:
- Company name and registered company number.
- Registration date and business status, when available.
- Industry categories and business groups.
- Province, district, and subdistrict.
- Directors, financial highlights, shareholders, rankings, and related records when provided by the source data.
Data quality and limitations
We process and structure the source data for search and browsing. Some records may be incomplete, unavailable in one language, subject to later corrections, or presented differently from the latest official record. SiamDir.net cannot guarantee that every record is complete, current, or error-free.
Permitted use and disclaimer
The information is provided for search, research, and general business reference. It should not be used as legal, financial, or official evidence. For decisions that require authoritative information, please verify the details with the relevant government agency or the original data source.
