Secretary of State Business Filings: What Data Is Available?
When a business entity is formed in any US state, the formation documents become public record maintained by the Secretary of State (or equivalent agency). This data is freely accessible, but what exactly is included — and how easy it is to access — varies significantly from state to state.
Standard Fields Across All States
Regardless of which state you are looking at, you can expect every formation filing to include the entity name (the legal name registered with the state), entity type (LLC, corporation, limited partnership, etc.), formation date, filing number (a unique identifier assigned by the state), and status (active, inactive, dissolved). These core fields are universal because they are required for the state to maintain its business registry.
Registered Agent Information
Every state requires a registered agent — a person or company designated to receive legal documents on behalf of the business. The registered agent's name and physical address (PO boxes are not allowed in most states) are part of the public filing. This is one of the most valuable fields for lead generation because it provides a contactable physical address and often reveals whether the business used a formation service.
Organizer and Principal Information
This is where states diverge significantly. Some states require the names and addresses of organizers (the people who filed the formation documents) and members or managers of the LLC. Texas includes organizer information in its Certificate of Formation. Florida lists the authorized representative. New York requires LLCs to publish formation in local newspapers, which generates additional public data.
Delaware, by contrast, is famously privacy-friendly. Delaware LLC filings do not require disclosure of member or manager names — only the registered agent. This makes Delaware formation data less useful for direct outreach, though the registered agent information still has value.
What Is NOT in the Filing
Formation filings generally do not include phone numbers, email addresses, revenue figures, number of employees, or industry classification. The filing tells you a business was formed, what it is called, and where its registered agent is located. Everything beyond that — owner contact details, business category, estimated revenue — requires enrichment from other data sources like LinkedIn, Google Maps, or commercial databases.
Accessing the Data
Each state provides access differently. Florida offers free bulk CSV downloads through Sunbiz — the most accessible format for anyone doing lead generation at scale. New York publishes formation data on its Open Data portal with a public API. Texas provides an online search but no official bulk export, requiring more effort to collect data systematically.
States like California and Delaware present technical challenges. California's bizfileonline portal is a modern React application with rate limiting that makes automated access difficult. Delaware's ICIS system uses legacy ASP.NET technology with ViewState tokens that complicate programmatic scraping.
Data Freshness
How quickly new filings appear in the public database also varies. Some states update their online systems in near real-time — a filing approved at 2pm appears in search results by 3pm. Others batch-process filings overnight, meaning today's approvals show up tomorrow morning. A few states lag by several days, particularly when processing volumes spike.
For lead generation purposes, data freshness is critical. A lead that is 24 hours old converts at dramatically higher rates than one that is seven days old. This is why services that monitor state databases continuously and deliver same-day or next-day data have a significant advantage over weekly or monthly batch providers.
