Delaware company search helps users find public business records connected with companies registered in Delaware. A Delaware business registration search can provide useful details such as an entity’s legal name, file number, entity type, formation date, status, and registered agent information. These records can help verify whether a company is registered with the Delaware Division of Corporations and identify basic filing information. Searching by company name or file number can make it easier to locate the correct business record and review available registration details.
Delaware company search provides a practical way to check business registration records and identify companies listed with the state. A Delaware business lookup may show information related to domestic corporations, LLCs, partnerships, and other registered entities. Users can search for a business name, compare entity details, and review publicly available filing information. A company registration search can be useful for checking business status, confirming an entity name, or locating basic state records before reviewing more detailed information from official Delaware sources.
How to Search a Delaware Business Registration
A Delaware business registration search can help identify an entity recorded with the Delaware Division of Corporations. The state’s online search allows users to look up a business by its entity name or file number. Search results can include both active and inactive entities, so the result itself should not be treated as proof of current status. The free record provides basic details such as the entity name, file number, formation or incorporation date, entity kind, type, residency, and registered-agent information where available.

- Official Delaware Entity Search: The Delaware Division of Corporations Entity Search page can be used to search public records for businesses and other legal entities registered in Delaware.
- Search by Entity Name: Enter the business’s legal entity name to search for its Delaware registration record. Using the exact spelling can help narrow the search results.
- Search by File Number: If you know the Delaware file number, you can use it to locate a specific business record. The file number is an identifier assigned to the entity’s Delaware state record.
- Review Matching Entities: The search may return multiple matching entities. For businesses with similar names, compare the entity name and file number to identify the correct record.
- Check Basic Registration Details: The selected record may show basic information such as the entity name, file number, formation or incorporation date, entity type or kind, and residency.
- Registered Agent Information: Where available, the search record may display the registered agent’s name, address, and telephone number.
- Active or Inactive Records: The free entity search can return both active and inactive entities. A search result by itself should not be treated as confirmation of the entity’s current status or good standing.
- Different From an EIN: Do not confuse a Delaware file number with an EIN. A file number identifies the entity’s Delaware state record, while an EIN is a federal tax identification number issued by the IRS.
Entity Registration Process
The Delaware entity registration process involves several steps that can apply at different stages of starting a business. A typical process begins with selecting a business name and choosing an entity structure, such as an LLC or corporation. The legal entity is then formed by filing the required formation document with the Delaware Division of Corporations. This creates the state entity record and establishes the company as a Delaware business entity.

- Choose a Legal Structure — First, select the appropriate legal structure for the business, such as an LLC, corporation, partnership, or another applicable entity type.
- Choose a Business Name — Select the proposed business name before starting the entity formation process. The name should meet Delaware’s applicable requirements.
- Start Entity Formation — The new business entity formation process can be started through Delaware One Stop.
- Complete Entity Forms — Provide the required information and complete the applicable entity formation forms.
- Submit Formation Documents — Submit the completed formation paperwork to the Delaware Division of Corporations. The One Stop page explains available options for preparing and submitting the documents.
- Delaware Legal Entity Formation — Once the filing process is completed, the entity becomes part of Delaware’s official legal business entity records.
- Registered Agent Requirement — Delaware legal entities must meet applicable registered agent and Delaware address requirements.
- Foreign Business Option — If a business was already formed in another state and wants to operate in Delaware, a separate foreign qualification process may apply.
- After Formation — After forming the entity, businesses operating in Delaware may need to complete business licensing, tax registration, EIN, and other applicable state or local requirements.
Business Registration Online Through One Stop
Delaware business registration online can involve several steps depending on the type of business and its activities in the state. Delaware One Stop serves as the state’s registration and licensing portal for businesses. A new business may use the portal to determine the appropriate registration path, while an existing Delaware entity may use it for business licensing and related registrations. Out-of-state businesses operating in Delaware may have separate registration requirements based on their activities and presence in the state.

Delaware LLC Registration Search
A Delaware LLC search can help users find basic registration information for a limited liability company recorded with the Delaware Division of Corporations. An LLC appears in Delaware entity records under its registered legal name, along with a state-assigned file number and other basic record details. The record may show the LLC’s formation date, entity type or kind, residency, and registered-agent information where available. A Delaware LLC lookup can help distinguish a particular LLC from businesses with similar names and provide basic information related to its LLC registration.
- Delaware Entity Name Search:
- https://icis.corp.delaware.gov/ecorp/EntitySearch/NameSearch.aspx
Search an LLC by Legal Name
An LLC can be searched by entering its legal name in the Delaware entity search. The name should match the business name recorded in the state database. Search results can contain multiple entities with similar names, so checking the complete legal name and file number can help identify the relevant LLC entity. A business may use a trade name or brand that differs from its legal entity name, so the registered legal name is the more relevant term for a Delaware company registration search.
Search by File Number
A Delaware LLC can also be located using its file number. This number is assigned to the entity’s state record and can identify a specific LLC more precisely than a name search. If the file number is known, entering it into the official Delaware search can help locate the corresponding record. The result may show the LLC’s legal name, formation date, entity type, and other basic information recorded by the state.
What a LLC Lookup Does Not Establish
A basic Delaware LLC lookup does not establish ownership, membership interests, manager information, EIN or federal tax details, complete filing history, or good standing. The free entity search can return both active and inactive entities, so the result itself should not be treated as confirmation of current status. Detailed status information or certified records may require separate services from the Delaware Division of Corporations.
Corporate Registration Search
A Delaware corporate registration search can help users find basic information about a corporation recorded by the Delaware Division of Corporations. A corporation appears in the state’s entity records under its legal corporate name and is assigned a corporate file number. A basic Delaware corporation search may show details such as the corporation’s entity type, incorporation date, residency, and registered-agent information where available. These details can help identify a particular corporation and distinguish it from entities with similar names. The corporate records filings is maintained by the state and reflects information recorded with the Division of Corporations.
Search a Corporation
A corporation registration record can be located by searching the corporation’s legal name or Delaware file number. Searching by name can return one or more matching entities, so users should compare the legal name and file number before selecting a record. The incorporation date indicates when the corporation was formed or incorporated in Delaware. The corporate file number serves as the state identifier for that entity’s record.
Review Corporate Registration Details
The search result may provide the corporation’s legal name, file number, incorporation date, entity type or kind, residency, and registered-agent information. The registered agent is the party recorded to receive certain legal notices and official communications for the entity. The basic search can contain both active and inactive entities. As a result, the search result alone does not establish the corporation’s current status or good standing. More detailed status information or certified records may require separate services from the Delaware Division of Corporations.
What Is a Business Registration Number?
A Delaware business registration number commonly refers to the identifying number associated with a business record maintained by the Delaware Division of Corporations. Delaware officially uses the term file number for this identifier. Each entity record has a unique file number that can be used to locate the business in the state’s entity search. People may use terms such as Company registration number Delaware, Business registration number Delaware, or registration number when referring to this state identifier.
Is a File Number the Same as a Business Registration Number?
The terms can be used interchangeably in general business searches, but Delaware file number is the official terminology used by the Delaware Division of Corporations.
- Official Delaware term: File number
- Common term: Business registration number
- Another common term: Company registration number Delaware
- Purpose: Identifies the entity’s Delaware state record
- Search use: Can be used to locate an entity in the Delaware Entity Search
- Assigned by: Delaware Division of Corporations
Is a File Number the Same as an EIN?
No. A Delaware file number and an EIN identify a business for different purposes.
- Delaware file number: Identifies an entity record maintained by the Delaware Division of Corporations.
- EIN: Federal Employer Identification Number issued by the IRS.
- FEIN: Another commonly used term for a federal EIN.
- File number: Used for Delaware entity records and state corporate filings.
- EIN/FEIN: Used for federal tax and other federal business purposes.
- Issuer: Delaware assigns the file number; the IRS issues the EIN.
Where Can You Find the Number?
The Delaware file number can be found through the state’s Business Entity Search.
- Search using the entity name.
- Review the matching entity record.
- Locate the file number in the record details.
- If the file number is already known, it can be used to locate the entity record.
- The file number is separate from the company’s EIN or FEIN.
Company Registration Cost and Fees
The Delaware company registration cost depends on the type of business entity, filing requirements, licenses, and ongoing state obligations. A new LLC or corporation may have an initial formation filing fee, while other expenses can apply for name reservation, business licensing, annual taxes, certificates, trade names, and industry-specific licenses. Reviewing each cost separately gives a clearer picture of the total Delaware business registration fees.
Business Registration Search vs. Business License Registration
The terms Delaware business registration and Delaware business license registration can refer to two different state processes. A business may first need to form or register its legal entity with the Delaware Division of Corporations. It may then need to register for a Delaware business license through the Division of Revenue if it conducts trade or business in the state. Delaware One Stop connects businesses with the applicable registration and licensing processes, but an entity record and a business license are not the same thing.
