A Delaware business entity search lets you confirm whether a company name is available before you file, and look up the official record of an existing Delaware corporation, LLC, or LP. Delaware is home to well over a million registered entities, including most of the S&P 500, so its records are among the most consulted in the country.
This guide walks through the official Delaware Division of Corporations search step by step, explains what each status label means, covers Delaware's real quirks (including a data-mining rule most guides ignore), and adds a section for non-US founders forming from abroad. If you are checking a name for a company you plan to start, this page is your starting point.
Key Delaware business search terms
Before you search, it helps to know the vocabulary Delaware uses. These terms appear throughout the official portal and on any record you pull.
| Term | What it means in Delaware |
|---|---|
| Entity / File Number | A 7-digit number Delaware assigns to every registered entity. It is the most reliable way to identify a company, since names can be similar. |
| EIN vs. File Number | The File Number is Delaware's internal ID. The EIN (Employer Identification Number) is a separate 9-digit federal tax ID issued by the IRS , the two are unrelated. |
| Certificate of Formation | The founding document for a Delaware LLC, filed with the Division of Corporations. Corporations file a Certificate of Incorporation instead. |
| Registered Agent | A person or company with a physical Delaware address who receives legal and state mail on the entity's behalf. Every Delaware entity must have one. |
| Active / Good Standing | The entity exists and has met its state obligations, including the Annual Franchise Tax. |
| Annual Franchise Tax | A flat $300 fee Delaware LLCs pay every June 1. Delaware LLCs do not file an annual report , paying the tax is the entire obligation. |
| Certificate of Good Standing | An official document confirming the entity is current on its obligations. Often required by banks, investors, and other states. |
| Name Availability | Whether your desired name is distinguishable from every existing Delaware entity. If not, the filing is rejected. |
| Name Reservation | Holding an available name for up to 120 days for a small fee, before you file. |
| Entity Lookup | The general act of searching the Division of Corporations database by name or file number. |
What is the Delaware business entity search tool?
The official tool is the Delaware Division of Corporations General Information Name Search, hosted by the Delaware Secretary of State:
https://icis.corp.delaware.gov/eCorp/EntitySearch/NameSearch.aspx
It is free to use and requires no account. You can search by Entity Name or by File Number. The free results show three things: the entity's name, its file number, and its current status. That is enough to confirm a name is taken or that a company is active.
What the free search does not show is the full record , registered agent details, formation date, certified standing, and copies of filed documents. Those require a paid order placed through the Division of Corporations (or a service provider). Delaware deliberately keeps the free tier lean, partly for privacy and partly to keep its commercial document business intact.
When to use a Delaware business entity search
-
Checking name availability before filing a new LLC or corporation, so your Certificate of Formation is not rejected.
-
Verifying a company's status , confirming a vendor, partner, or supplier is active and in good standing.
-
Finding an entity's file number when you need it for a filing, an order, or due diligence.
-
Due diligence before signing a contract, investing, or acquiring a business.
-
Confirming a competitor or similar name exists, to gauge how distinguishable your own name will be.
-
Locating the formation record of a company you already own but whose details you have lost.
Step-by-step: how to search the Delaware database
Step 1 , Open the official portal
Go to icis.corp.delaware.gov/eCorp/EntitySearch/NameSearch.aspx. You will land directly on the General Information Name Search page. No login is needed. Always start at the .gov address rather than a third-party copy, so you know the data is current and authoritative.
Step 2 , Choose your search method
You have two options. Search by Entity Name when you are checking availability or looking up a company by its trade name. Search by File Number when you already know the 7-digit ID and want an exact match. File-number search is faster and avoids the ambiguity of similar names.
Step 3 , Enter your terms with Delaware's matching rules in mind
Delaware's name search matches on the words you enter. Try the distinctive part of the name first ("Bastion") rather than the full legal string including "LLC." Entity designators (LLC, Inc., L.P.) and common words can be searched, but the most useful results come from the unique core of the name. If you get too many results, add a second word to narrow it.
Step 4 , Read the results
The free results list returns the entity name, the file number, and the status. Scan for an exact or near-exact match to your intended name. If a similar name already exists and is active, Delaware may consider yours not "distinguishable," which can block your filing. The file number lets you identify the precise record if several names look alike.
Step 5 , Order full details or documents (optional)
To see the registered agent, formation date, certified good-standing status, or copies of filed documents, place a paid order through the Division of Corporations. This is the step that converts a quick free check into a certified record you can hand to a bank or investor.
Delaware entity status definitions
| Status | What it tells you |
|---|---|
| Active / Good Standing | The entity is properly registered and current on its Franchise Tax and obligations. Safe to transact with. |
| Cancelled | The entity has been formally dissolved or its registration ended. It no longer legally exists in Delaware. |
| Ceased Good Standing / Delinquent | The entity exists but has fallen behind , typically an unpaid Annual Franchise Tax. It can usually be restored by paying what is owed plus penalties. |
| Void | A more serious lapse, often from prolonged non-payment. The entity's standing has been forfeited and must be revived to do business. |
| Pending / Filed | A newly submitted filing that is processing or recently completed. |
Delaware-specific quirks and tips
Delaware behaves differently from most states in ways that matter when you search and when you form.
-
No annual report for LLCs. This is the single most misunderstood Delaware fact. Delaware LLCs do not file an annual report. They simply pay a flat $300 Annual Franchise Tax due every June 1. (Corporations are the ones that file annual reports.) Miss the deadline and you owe a $200 late penalty plus 1.5% monthly interest , so the obligation is small but unforgiving.
-
The free search is intentionally limited. Name, file number, and status only. Anything certified or detailed is a paid order , budget for it if you need proof of good standing.
-
Delaware prohibits data-mining. The Division of Corporations explicitly forbids excessive automated or scripted searches against its database. Run your lookups by hand; do not point a scraper at the portal, or your access can be cut off. Few competitor guides mention this, but it is a real rule.
-
7-digit file numbers. Unlike the alphanumeric IDs some states use, Delaware assigns a clean 7-digit file number to every entity , handy for unambiguous lookups.
-
Member privacy. Delaware does not list LLC members or managers in the public record. The owners of a Delaware LLC are not visible through the entity search, which is part of why founders value Delaware for privacy.
-
No state income tax for out-of-state activity. A Delaware LLC that does not operate inside Delaware owes no Delaware state income tax , only the $300 franchise tax.
-
The prestige trade-off. Delaware is the investor and venture-capital standard, backed by the Court of Chancery, the most respected business court in the US. That credibility is real, but the $300/year franchise tax is higher than Wyoming's, and arguably overkill for a solo founder who is not raising money.
What to do if the name is available , or already taken
If the name is available, you have two moves. You can reserve it for up to 120 days for a small state fee, which holds it while you prepare your paperwork. Or you can move straight to filing your Certificate of Formation (state filing fee $110) and lock the name in by registering the entity itself.
If the name is taken, you still have options. Tweak the name so it is distinguishable from the existing entity (add or change a distinctive word , not just "LLC"). Check whether the conflicting entity is cancelled or void, in which case the name may free up. Consider a different entity designator, or operate under a DBA. And remember: a clear Delaware entity search is not a trademark clearance , for brand protection, search the USPTO separately.
Delaware business entity search for non-US founders
You do not need to be a US citizen, US resident, or hold any particular visa to form a Delaware LLC, and you never need to visit the United States to do it. Founders of any nationality can own a Delaware company outright.
The entity search works identically for you , it is a public, browser-based tool with no US login required. The practical difference for non-residents comes after the search, at formation: you will need a US registered agent (a Delaware requirement no foreign founder can satisfy alone), and you will need an EIN from the IRS without an SSN, which involves filing Form SS-4 and receiving the IRS CP-575 confirmation letter. Both are routine, but both are where international founders most often get stuck.
That is exactly what Bastion handles. We confirm your name is clear, file the Certificate of Formation, secure your EIN with the CP-575 letter even if you have no SSN, provide your registered agent and a US mailing address with mail scanning, draft your operating agreement, and help you open a US bank account , all remotely.
