Data coverage

What data is available on electricity & power in Thailand

Thailand business database

Firmographics

Legal name, registered address, NACE sub-sector, legal form, founding year and website. Every record is keyed to its Tax ID — the stable Thailand Department of Business Development (DBD) identifier that survives name changes and rebrands, making it the most reliable CRM deduplication key for Thailand data.

Points of interest

Each company is geocoded to GPS coordinates covering its registered seat and operating locations across Thailand, with a precision level on every point — useful for territory planning and proximity targeting.

Tax IDs

Records carry the Tax ID and, where applicable, the VAT registration number, with a flag for when the two coincide. These are the cleanest match keys for enriching lists and cross-referencing against the national tax authority and your CRM.

Group structure

InfobelPRO resolves the corporate hierarchy — parent, subsidiaries and the size of the worldwide corporate family — so sales and compliance teams can see who controls an entity before engaging or onboarding it.

Financials

Annual revenue in local currency, EUR and USD, employee headcount and founding year, with multi-year history where filed. Figures are sourced from Thailand Department of Business Development (DBD) filings and carry an Actual-or-Modeled reliability flag.
