Data Sources

New Hampshire uses a single live integration against the New Hampshire Department of State, QuickStart Business Register (quickstart.sos.nh.gov). The register is the official record for every domestic and foreign for-profit and nonprofit corporation, limited liability company, limited partnership, limited liability partnership, professional limited liability company, professional association, trade name, and trademark filed in New Hampshire.
Live-only. The New Hampshire Department of State does not publish a free open-data feed or bulk CSV export. Per-snapshot XML extracts are available only via a paid authenticated subscription. Every lookup resolves live against the QuickStart register. There is no non-authoritative fast path.
Each entity record published by the register includes: legal name, NH Business ID, business type, current status, management style (LLC), citizenship of formation, business creation date, home-jurisdiction formation date, principal and mailing addresses, annual-report years, NAICS principal-purpose rows, the full list of officers and directors with titles and business addresses, and the registered agent with office and mailing addresses.

The NH Business ID has no fixed length and no leading zeros. Observed values as of May 2026 range from roughly 100000 to 999000, but the register does not impose a minimum digit count. Pass the number as-is.
