How to do a Delaware business entity search
There are two ways you can search for a business entity in Delaware:
- With the entity name
- With the entity file number
Let’s look at how each of these search methods work.
Search with entity name
To do a search by business name, you will need to know the exact business name or some keywords or phrases used in the business name.
Step 1: Access the DE Division of Corporation website
The first step is to access the State of Delaware Department of State (Division of Corporations) business entity search tool to retrieve information about a business, corporation, entity or organization registered in Delaware.

Step 2: Search for the business entity name
To search for a business entity or corporation, you should enter the actual company name or a word or phrase included in the company name.
In our example, we typed the word “Apple” and here are the results that we get:

Step 3: Select the business entity matching your search
The search results will provide you with a list of matching company names along with their associated file number.
Select the company that you were looking for by clicking on the company name appearing with a hyperlink.

Step 4: Business entity details
When you click on the company name, you will be brought to the “Entity Details” page where you will have access to free information made available by the State of Delaware.
On the Entity Details page, you will see the following information:
- File number (business entity file number)
- Entity name (business entity name)

Search with file number
You can also do a search with a business entity’s file number.
If you have a business entity’s file number, you can accelerate your search by targeting the specific company that you are looking for.
Considering that each registered corporation or business entity will have its own unique file number, when you do a file number search, you will get one result on the search results page.
Step 1: Access the DE Division of Corporation website
To do a file number search, the first step is identical to a business entity name search.
Access the Delaware business search tool.
Step 2: Enter a business entity file number
Enter the business file number in the “File Number” field.

Step 3: Select the business entity matching your search
Click on the company available on the search results page.
There should only be one entity matching your file number search.

Step 4: Consult the Entity Details page
Then click on the company’s name appearing on the search result that is presented in a hyperlink format.
This will lead you to the “Entity Details” page.
