Looking up a business in Connecticut? Here’s a hard truth most people miss: the real power of the Connecticut Business Entity Search isn’t just in finding a company—it’s in everything else the database quietly reveals. Whether you’re a journalist, investor, compliance officer, or just a curious citizen, knowing how to navigate this tool can give you an edge. This guide will show you exactly how.
What Is the Connecticut Business Entity Search?
The Connecticut Business Entity Search is a free online database maintained by the Connecticut Secretary of the State. It’s the official registry for all business entities operating in the state—from LLCs and corporations to nonprofits and trade names. You can access it here: Connecticut Online Business Search
But this isn’t just a registry. It’s a forensic tool. If you know how to look, you can find out who owns a company, whether it’s in good standing, how long it’s been around, and even if it’s had name changes or past legal filings.
Why the Connecticut Business Entity Search Database Matters
- Due Diligence: Whether you’re forming a partnership or investing, verifying a company’s legitimacy is non-negotiable.
- Investigative Research: Reporters, attorneys, and watchdogs use it to follow paper trails.
- Competitive Intelligence: Spot industry trends and identify regional players.
- Legal Compliance: Ensures your entity name isn’t already taken or too similar.
- Historical Verification: The filing and name history can help build a corporate timeline for litigation or research.
These use cases are not theoretical. In 2023, a local news organization used the Connecticut Businesses Entity Search to ascertain that a major contributor to a mayoral campaign funneled money through three different shell corporations of which all were registered to residential address and had shared agents.
How to Use the Connecticut Business Entity Search
1. Start with the Simple Search
On the homepage, you’ll find a basic search bar. You can enter:
- Business Name
- Business ALEI (a unique identifier assigned by the state)
- Filing Number
Want to be precise? Check the box labeled “Search on exact name”.
Example: If you enter “Evergreen Holdings” with the exact name box checked, you’ll get only that specific legal name—not “Evergreen Holdings LLC” or “Evergreen Investment Group”.
2. Advanced Search Features
Need more control? Use the Advanced Search tab. You can filter by:
- Business Status (e.g., Active, Dissolved)
- Entity Type (e.g., LLC, Corporation, Nonprofit)
- Date Formed
- Business Type/Sub-status
This is particularly useful for narrowing down industry sectors or tracking newly registered companies.
Tip: You can combine filters. For instance, search for all Active Nonprofits formed after 2020 that operate under a trade name.
Understanding the Connecticut Business Entity Search Results
Once your search yields results, the page will display a table listing:
- Business Name
- ALEI
- Status
- Type
- Date Formed
Clicking any business name reveals the full profile. And this is where things get interesting.
What You Can Learn from a Single Business Entry in the Connecticut Business Entity Search
Clicking through to a specific business opens a rich data panel with four major sections:
1. Business Details
Includes:
- Business Name & Status
- Place of Formation
- Business and Mailing Address
- NAICS Code and Sub-Code
- Date Formed
- Public Substatus
- Whether Annual Reports Are Required
- Last Report Filed
- Business ALEI
Pro Tip: The NAICS code reveals the industry. Cross-reference it with NAICS.com to understand the business sector.
2. Principal Details
Lists:
- Principal’s Name and Title
- Business Address
- Residential Address
This is particularly useful for identifying real decision-makers behind shell companies.
The principal’s home address may be redacted because of any number of issues regarding privacy; however, the business address can provide valuable information on its own. For example, if the business listed the principal’s name and the same address as multiple other businesses, there could be quite a few possibilities! This could uncover the possibility of a parent company or support for any number of franchise models.
3. Agent Details
Includes:
- Registered Agent Name
- Business Address
- Mailing Address
Registered agents typically operate through commercial services; however, in a small business, it could often be the owner themselves. Knowing the difference can be important when it comes to fraud and enforcing a contract.
4. Filing History
A timeline of legal filings, showing:
- Filing Date
- File ID
- Volume Type
- PDF Downloads
Tip: Click “View as PDF” to access official state filings. This might include incorporation documents, amendments, or reinstatement notices.
This function allows users to verify whether a company has submitted annual reports or failed to do so—a sign of dormancy or legal trouble.
5. Additional Tabs
- Name History: Any past business names used.
- Trade Names: DBAs (Doing Business As) the company has registered.
- Shares: For corporations, this section shows authorized shares.
You can download or print all this using the “Print Business Details” button.

Limitations of the Connecticut Business Entity Search You Should Know
While this tool is powerful, it has a few constraints:
- No real-time updates (filings can take days to process).
- No financial disclosures.
- No enforcement or licensing data—you’ll need to cross-reference with other state agencies.
- No bulk export or API support.
That said, these limits can be partially overcome with patience and creative research. For instance, combining Connecticut’s data with national platforms like EDGAR can provide deeper insight into registered corporations that also trade publicly.
For deeper research, consult the Connecticut Business Knowledge Base for official how-tos and support.
