Delaware’s free business entity search is famously limited, and most guides overstate what it shows. It will not tell you who a company’s registered agent is, whether it is in good standing, or if its franchise tax is paid. The actual tool is the ICIS General Information Name Search, where ICIS stands for Integrated Corporate Information System, run by the Delaware Division of Corporations at icis.corp.delaware.gov. The free results show an entity name and file number, nothing more.
The Delaware Division of Corporations sits under the Delaware Department of State, so “Secretary of State (SOS) search” and “Delaware SOS business entity search” all point to the same ICIS tool. This search matters more than any other state’s: the Division of Corporations reports more than 2.28 million registered entities as of its 2025 Annual Report, including over two-thirds of the Fortune 500.
What Is the Delaware Business Entity Search?
The Delaware business entity search is the free public name lookup run by the Delaware Division of Corporations through its ICIS General Information Name Search. The Division of Corporations is a statutory division of the Department of State, per 29 Del. C. § 8704, which is why “Secretary of State search” means the same tool. Use it for name availability, to find an entity’s file number, and as the first step of due diligence.
What Does the Free Delaware Entity Search Actually Show?
The free ICIS results list shows only the entity name and file number. Clicking through to the detail page adds formation date, entity kind, entity type, residency, and state. It shows nothing about the registered agent, no name, address, or contact detail. Status, good standing, franchise tax position, and filing history are paid-only, ordered through a status report or certificate.
Two labels confuse people. Entity kind is the legal form (Corporation, LLC, LP). Entity type is the classification within it (General, Bank, Non-Profit), per Delaware’s own detail-page fields. The formation date appears on the detail page only, while the file number appears in both the results list and the detail page.
| Data point | Free ICIS search | Paid status report or certificate | Source |
|---|---|---|---|
| Entity name | Yes | Yes | Delaware Division of Corporations, ICIS name search |
| File number | Yes | Yes | Delaware Division of Corporations, ICIS name search |
| Formation date, entity kind, entity type, residency, state | Detail page only | Yes | Delaware Division of Corporations, ICIS name search |
| Registered agent name and address | No | No (ordered separately) | Delaware Division of Corporations, ICIS name search |
| Current status and good standing | No | Yes | Delaware Division of Corporations, Services page |
| Franchise tax position and filing history | No | Yes (long form) | Delaware Division of Corporations, Services page |
The ICIS page itself warns that results include both active and inactive entities and are not an indication of current status, per the Delaware Division of Corporations ICIS name search.
How Do You Perform a Delaware Business Entity Search?
Go to the ICIS General Information Name Search at icis.corp.delaware.gov, or start at corp.delaware.gov and follow the entity search link. Enter an entity name or file number, review the name-and-file-number results list, then click an entity to open its detail page. The tool offers no filters by status, entity type, or filing date, no registered agent or officer search, and no download or print function.
Search tips: drop “LLC” or “Inc.” to widen results, try spelling variations, and use quotation marks for an exact match. The search is not fuzzy, per the Delaware Division of Corporations ICIS tool, so a near-miss spelling returns nothing.
Can You Search a Delaware Entity by File Number?
Yes. The file number is a 7-digit identifier assigned at formation, searchable directly in the ICIS name search. It is also required to enter the franchise tax and annual report flow, which prompts for the Business Entity File Number, per the Delaware Division of Corporations franchise tax portal. Use the file number as the stable identifier when several similar names appear in one results list.
How Do You Check Business Name Availability in Delaware?
Search the exact name and close variations in ICIS; no matching results means the name is likely available, which you then lock in through the Division’s name reservation. A Delaware name reservation costs $75.00 and holds the name for 120 days, per the Delaware Division of Corporations name reservation page. The name must be distinguishable from every entity already reserved or registered under Delaware law, per Delaware’s Business First Steps portal.
Availability in Delaware is not trademark clearance. A name can be free to register in Delaware and still infringe a federal trademark, so run a separate United States Patent and Trademark Office (USPTO) search before you commit.
Which Entity Types Appear in the Delaware Entity Search?
Only entities that file formation documents with the Division of Corporations appear in ICIS: corporations, LLCs, Limited Partnerships (LPs), Limited Liability Partnerships (LLPs), statutory trusts, and general partnerships that filed a Statement of Partnership Existence. A Delaware statutory trust is a filed trust entity used for investment funds and structured deals, and it appears because it files with the Division.
Sole proprietorships and informal general partnerships never file with the Division of Corporations, so they do not appear in ICIS at all; they register trade names at the county Prothonotary level. One more clarification: Delaware files a “Corporation,” and S-corporation status is a federal Internal Revenue Service (IRS) election that never shows in the search.
Delaware’s registry skews heavily toward LLCs, per the Division of Corporations 2025 Annual Report.
| Entity kind | Registered count (year-end 2025) | Source |
|---|---|---|
| LLCs | 1,653,329 | Delaware Division of Corporations, 2025 Annual Report |
| Corporations | 425,765 | Delaware Division of Corporations, 2025 Annual Report |
| LPs and LLPs | 177,520 | Delaware Division of Corporations, 2025 Annual Report |
| Statutory trusts | 31,114 | Delaware Division of Corporations, 2025 Annual Report |
| Total entities | 2,287,728 | Delaware Division of Corporations, 2025 Annual Report |
What Do Delaware Entity Statuses Mean?
The free search does not display status; you see it only through a paid status report or certificate of good standing. Delaware uses its own designations, not “Active” or “Inactive.” Good Standing means current on franchise tax and filings; the others signal escalating trouble.
| Status | What it signals | Source |
|---|---|---|
| Good Standing | Current on franchise tax and required filings | Delaware Division of Corporations, Services page |
| Cease Good Standing | Missed a requirement, usually franchise tax or annual report | Delaware Division of Corporations, Services page |
| Void (corporations) / Cancelled (LLCs, LPs) | Lost the right to conduct business | Delaware Division of Corporations, Services page |
| Forfeited | Lost authority, often a lapsed registered agent | Delaware Division of Corporations, Services page |
| Dissolved | Voluntarily wound up and filed to close | Delaware Division of Corporations, Services page |
| Merged / Converted | No longer exists independently | Delaware Division of Corporations, Services page |
How Do You Check If a Delaware LLC Is in Good Standing?
Order the paid status report (roughly $10 as of July 2026) or a certificate of good standing; the free ICIS search cannot confirm good standing, per the Delaware Division of Corporations Services page. Franchise tax and annual report status are exactly what knock an entity out of good standing, and they are visible only through the paid flow. The common causes of Cease Good Standing are unpaid franchise tax, a missing annual report, and no registered agent.
How Do You Request a Delaware Certificate of Good Standing?
Order a certificate of good standing online, by mail, or through a registered agent from the Division of Corporations. The short form costs roughly $50 and the long form with full filing history roughly $175, both as of July 2026 per the Delaware Division of Corporations fee schedule. Banks and lenders usually accept the short form; M&A due diligence and foreign qualification often require the long form.
How Do You Reinstate a Forfeited Delaware Entity?
File a certificate of revival (corporations) or certificate of revival or renewal (LLCs and LPs), then pay all back franchise taxes, penalties, and registered agent fees, per the Delaware Division of Corporations. Delaware charges a $200 penalty plus 1.5% monthly interest on unpaid LLC and LP annual tax. Corporations can be declared void after two-plus years of unpaid franchise tax, and a registered agent must be in place before revival.
How Do You Use the Delaware Entity Search for Due Diligence?
Confirm the exact legal name and file number in ICIS, pull the paid status report for standing and franchise tax, then order the long-form certificate for the full filing history. The real limitation: Delaware offers no search by registered agent, officer, or owner name, per the Delaware Division of Corporations ICIS tool. Ownership is private, so beneficial-owner diligence needs company records or other sources.
Why Does the Delaware Entity Search Return No Results for a Real Company?
ICIS matches on the exact characters you enter, so a real company can return nothing when your spelling or suffix differs. Drop “LLC” or “Inc.,” try name variations, and remember that a company may be registered under a different legal name than its brand. When the name will not resolve, search the 7-digit file number instead, which is the stable identifier per the Delaware Division of Corporations ICIS tool.
