Database overview
Distributions across all 2,554 energy companies in Switzerland — registry-sourced from Zefix and refreshed daily.
These distributions are computed from the full Swiss energy companies database, not the sample above.
Data coverage
Legal name, registered address, NACE sub-sector, legal form, founding year and website. Every record is keyed to its CHE Number — the stable Zefix identifier that survives name changes and rebrands, making it the most reliable CRM deduplication key for Switzerland data.
Each company is geocoded to GPS coordinates covering its registered seat and operating locations across Switzerland, with a precision level on every point — useful for territory planning and proximity targeting.
Records carry the CHE Number 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.
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.
Annual revenue in local currency, EUR and USD, employee headcount and founding year, with multi-year history where filed. Figures are sourced from Zefix filings and carry an Actual-or-Modeled reliability flag.
