Delaware’s free business entity search is deliberately minimal, and most guides overstate it. The 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. It will not tell you whether a company is in good standing or whether its franchise tax is paid. Those answers cost extra.
The Division of Corporations sits under the Delaware Department of State, so “Secretary of State (SOS) search,” “DE SOS business search,” and “Delaware SOS business entity search” all point to the same ICIS tool. This search matters more than any other state’s. Delaware reports 2,287,728 registered entities in 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 is a statutory division of the Department of State under 29 Del. C. § 8704, which is why “SOS search” and “DE SOS business search” mean the same tool.
Delaware recorded 2,287,728 registered entities in its 2025 Annual Report, per the Division of Corporations stats page. That supersedes the “more than one million business entities” copy still published on the Division’s own homepage, which has sat unchanged since 2016 while the real count more than doubled. Use the exact 2.28 million figure.
What Does the Free Delaware Entity Search Actually Show?
The free results list shows the entity name and file number only. The detail page adds formation date, entity kind, entity type, residency, state, and the registered agent’s name, address, and phone number. Status, good standing, and franchise tax position are paid-only. The table below shows the split.
| 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, address, phone number | Detail page only | Yes | 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 |
One correction worth flagging: the free detail page does show the registered agent. The ICIS disclaimer states the free data “consists of the entity name, file number, incorporation/formation date, registered agent name, address, phone number and residency,” per the Delaware Division of Corporations ICIS name search. The same page warns that results include both active and inactive entities and are not an indication of current status.
What Is the Difference Between Entity Kind and Entity Type in Delaware?
Entity kind is the legal form, and entity type is the classification within it. Kind means Corporation, Limited Liability Company (LLC), or Limited Partnership (LP). Type means the category inside that form, such as General, Bank, or Non-Profit, per Delaware’s own detail-page field labels. A worked example: kind “Corporation,” type “General.”
Two field-location facts help you read a result. The formation date appears on the detail page only. The file number appears in both the results list and the detail page. One boundary clarification ties to the distinction: an S-corporation is a federal Internal Revenue Service (IRS) tax election, not an entity kind, which is why it never appears in the 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, type, or filing date, no officer search, and no download or print function.
Search tips help you find a stubborn record. 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 filing flow, which prompts for the Business Entity File Number, per the Delaware Division of Corporations Services page.
If you do not have the file number, search by name first and read it off the results list. Use it as the stable identifier when several similar names cluster in one result set.
How Do You Check Delaware Business Name Availability?
Search the exact name and close variations in ICIS. No matching results means the name is likely available, which you then lock in through a 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.
Availability in Delaware is not trademark clearance. A name can be free to register in Delaware and still infringe a federal mark, so run a separate United States Patent and Trademark Office (USPTO) search before you commit. For a fast first pass, Commenda’s company name checker screens name availability before you file.
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, LPs, Limited Liability Partnerships (LLPs), statutory trusts, and general partnerships that filed a Statement of Partnership Existence. A Delaware statutory trust appears because it files with the Division.
Sole proprietorships and informal general partnerships never file with the Division, so they do not appear at all. They register trade names at the county Prothonotary, a separate filing system from the state Division of Corporations, which is why ICIS never shows them. The registry skews heavily toward LLCs.
| 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 |
How Do You Look Up the Registered Agent for a Delaware Company?
The free ICIS detail page shows the registered agent’s name, address, phone number, and residency. The Division’s own on-page disclaimer lists this among the data provided free of charge, per the Delaware Division of Corporations ICIS name search. Older guides claiming the free search hides the agent are wrong.
What the search will not do is run in reverse. Delaware offers no search by registered agent name, officer name, or owner name. The contrast with other registers is sharp. The United Kingdom’s Companies House lists company officers for free, while Delaware publishes the registered agent but no officers, directors, or shareholders.
What Do Delaware Entity Statuses Mean?
The free search never displays status; you see it only through a paid status report or certificate of good standing. Delaware uses its own designations rather than plain “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 |
Unpaid franchise tax and a missing annual report are the dominant reasons an entity leaves Good Standing. A lapsed registered agent sits behind most Forfeited statuses.
How Do You Check If a Delaware Company Is in Good Standing?
Order a paid status report (about $10 as of October 2026) or a certificate of good standing from the Division of Corporations. The free ICIS search cannot confirm 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 both are visible only through the paid flow.
Keeping an entity in Good Standing is a calendar problem. Commenda’s compliance calendar tracks Delaware franchise tax and annual report deadlines so standing never lapses by surprise.
How Do You Order 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 October 2026 per the Delaware Division of Corporations fee schedule.
Which form you need depends on the recipient. Banks and lenders usually accept the short form. Mergers and acquisitions (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 a 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.
One condition blocks everything else. With no registered agent in place, revival cannot proceed at all. The agent must exist before you file the 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 free search is step one, not the whole story, because its active-and-inactive results are not proof of standing.
The hard limits matter for diligence. Delaware offers no search by registered agent, officer, or owner name, and ownership never touches a state filing. Beneficial-owner diligence needs company records or other sources. Delaware publishes far less than the UK’s Companies House, Germany’s Handelsregister, or India’s Ministry of Corporate Affairs (MCA) filings.
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. It is the stable identifier, per the Delaware Division of Corporations ICIS tool.
