Data coverage
United States business database
Legal name, registered address, NACE sub-sector, legal form, founding year and website. Every record is keyed to its Registration number — the stable SEC EDGAR identifier that survives name changes and rebrands, making it the most reliable CRM deduplication key for United States data.
Each company is geocoded to GPS coordinates covering its registered seat and operating locations across United States, with a precision level on every point — useful for territory planning and proximity targeting.
Records carry the Registration 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 SEC EDGAR filings and carry an Actual-or-Modeled reliability flag.
