What Are the Requirements for Registering a Company in the U.S.? A Comprehensive Guide to Incorporation Procedures, Requirements, Company Registration Numbers, and Trademark Registration

Registering a company in the United States is far more complex than simply setting up an online store or filling out a form-and it’s certainly not as simple as hiring an agent and paying a fee. In practice, every step-including selecting the appropriate business entity type, choosing the state of registration, initiating tax compliance, and fulfilling ongoing annual reporting obligations-directly affects whether your company can operate lawfully, open a U.S. bank account, file taxes, or even apply for a trademark.

Beginning January 1, 2026, the U.S. Department of the Treasury will fully implement the Corporate Transparency Act (CTA). Under this law, all newly formed domestic and foreign-reporting companies must submit Beneficial Ownership Information (BOI) to the Financial Crimes Enforcement Network (FinCEN). Failure to file timely carries a penalty of $500 per day-a regulation that has already triggered reminder emails to numerous cross-border entrepreneurs just two months after their company formation.

Requirements for Registering a U.S. Company

U.S. citizenship or lawful permanent resident (green card) status is not mandatory to register a company in the United States. However, the following fundamental requirements must be met

1. At least one company officer (e.g., director, manager, or member) must be designated and must provide their full legal name, date of birth, residential address, and a valid government-issued identification document (e.g., passport or driver’s license);

2. A Registered Agent must be appointed. This agent must maintain a physical street address within the state of registration and be authorized to accept legal documents (e.g., service of process) on behalf of the company;

3. The company name must be unique within the chosen state and must include a legally recognized entity designator-such as “LLC,” “Inc.,” or “Corp.”;

4. A principal business address must be provided. This may differ from the Registered Agent’s address, but a P.O. Box is not acceptable;

5. The company’s management structure must be clearly defined-for example, an LLC may opt for member-managed or manager-managed governance, while a corporation must establish a board of directors.

Streamlined Steps to Form a U.S. Company

Using the Limited Liability Company (LLC)-the most common entity type in Delaware or Wyoming-as an example

1. Verify name availability via the Secretary of State’s official website (free search);

2. Prepare and file the Articles of Organization with the Secretary of State’s office (primarily online; filing fees range from $40 to $500, depending on the state);

3. Receive the Certificate of Formation (or Certificate of Organization), issued by the state;

4. Apply for a Federal Employer Identification Number (EIN) through the IRS website-free of charge, typically issued within 24 hours;

5. Open a U.S. business bank account (requires EIN, corporate formation documents, officer identification, and verifiable U.S.-based contact information);

6. Submit the BOI report to FinCEN (for companies formed on or after January 1, 2026, the filing must be completed within 30 calendar days of formation).

Key Practical Details in U.S. Company Registration

A Registered Agent cannot be a virtual mailbox provider or a non-U.S. address. Some states-including New York-further require the Registered Agent to sign a written consent form.

An LLC is not required to hold an initial meeting of members or managers; however, adopting an Operating Agreement is strongly recommended-especially for multi-member LLCs-to formally define roles, responsibilities, profit/loss allocation, and governance procedures.

All companies must file an Annual Report with their state of formation each year. Fees vary widely-from $0 to several hundred dollars-depending on the state. Late filings may result in penalties or administrative dissolution.

Even if the company conducts no business activity, any entity holding an EIN remains obligated to file zero-return tax forms (e.g., federal Form 1120 or state equivalents) as required by federal and state authorities. Failure to do so may negatively impact the company’s credit standing and regulatory compliance record.

Types of U.S. Company Identification Numbers

The United States does not issue a single, unified “company registration number.” Instead, three distinct identification numbers are used in practice

1. State File Number Assigned by the Secretary of State upon formation and printed on the Certificate of Formation; used for state-level administrative and legal purposes;

2. Employer Identification Number (EIN) Issued by the Internal Revenue Service (IRS); a nine-digit number formatted as XX-XXXXXXX; essential for opening a bank account, filing federal and state taxes, hiring employees, and other official transactions;

3. FinCEN BOI Confirmation Number A unique reference number automatically generated upon successful submission of the BOI report to FinCEN. It is confidential and intended solely for tracking and verifying the status of your BOI filing.

U.S. Trademark Registration Process (Brand Protection)

Trademark protection is a separate legal process administered exclusively by the United States Patent and Trademark Office (USPTO)-and is entirely independent of company formation

1. Conduct a comprehensive trademark search using the USPTO’s Trademark Electronic Search System (TESS) to assess potential conflicts with existing marks;

2. Accurately identify the relevant International Classes of goods/services (45 classes total); precise classification is critical to scope and enforceability;

3. File a trademark application-either under an “Intent-to-Use” (ITU) basis (for marks not yet in commerce) or a “Use-in-Commerce” basis (for marks already actively used in U.S. interstate or international trade);

4. Undergo examination by a USPTO examining attorney (average processing time 8-12 months; office actions may be issued requiring formal response);

5. Enter the 30-day publication period in the Official Gazette, during which third parties may file oppositions;

6. Upon successful registration, receive a U.S. Trademark Registration Number. The registration is valid for 10 years and requires submission of a Declaration of Use (Section 8) between the 5th and 6th years post-registration to maintain validity.

The above outlines the core principles and practical considerations for registering a company and protecting a brand in the United States. We hope this information proves helpful to you.
