US Company Search 2026: How to Check a US Company

In 2026, a US Company Search is an important step for overseas entrepreneurs, investors, and businesses that plan to work with a US company. It can help you confirm whether a company is properly registered, check its basic business information, and reduce potential risks before a transaction or partnership.

Unlike countries with one national company registry, the US generally manages business registrations at the state level. Therefore, you usually need to know the state where the company was formed before starting a US Company Search.

This guide explains the main ways to search US company information, what to check, and what to keep in mind when using public records.

Why Do a US Company Search?

A US Company Search can help you understand a company’s basic registration and public information. This is especially useful before starting a business relationship.

1. Verify Company Registration

First, you can check whether a company has an official registration record and whether its current status is active. This can help you avoid dealing with a company that does not exist or has provided incorrect information.

2. Check Company Background

A state business record may show the company’s legal name, entity type, registration date, registered agent, address, status, and filing history. However, the information available varies from state to state.

3. Support Investment and Business Decisions

Before investing in, acquiring, or working with a US company, checking its public records can provide useful background information. In addition, a US Company Search can help you identify possible differences between the information provided by a company and its public records.

For larger investments or acquisitions, however, a basic search should be combined with proper legal and financial due diligence.

4. Confirm the Company’s Identity

Some businesses may have similar names. Therefore, you should compare the legal name, registration number, state, address, and other available details to make sure you are checking the correct company.

Main Ways to Search US Company Information

1. Search State Government Websites

The most direct way to conduct a US Company Search is through the official business entity database of the relevant state.

Most states provide an online search system. Depending on the state, you may search by company name, entity number, registered agent, or other information. For example, Georgia’s official system allows searches by business name, control number, registered agent, and officer name.

Below are the main official business search websites for all 50 states:

These are government-operated search portals or official government business-record pages. For example, Delaware’s system provides basic entity information such as the entity name, file number, formation date, and registered agent. Wyoming also allows users to search registered entities by entity name or filing ID.

2. Use Federal Business Records

In addition to state databases, you can use federal records when appropriate.

The US Securities and Exchange Commission (SEC) provides the EDGAR system, which contains public filings from companies required to report to the SEC. These records can be useful when checking publicly traded companies.

However, EDGAR is not a complete database of all US companies. Many private LLCs and small businesses will not have detailed records there.

3. Check Business Credit Reports

Some commercial information providers offer company credit reports and business background information. These reports may include payment history, credit information, and other business data.

Because some services charge fees, they are generally more suitable when you need a deeper review.

4. Check the Company Website

You can also visit the company’s official website or contact its representatives. This may help you confirm its address, contact details, services, and business background.

However, information provided directly by a company should still be compared with official records when it is important.

What Should You Check in a US Company Search?

1. Confirm the Registration State

Each state has its own business registration system. Therefore, you should first confirm where the company was formed.

If a company operates in several states, it may also have registrations in other states. In that case, you may need to check more than one database.

2. Check When the Information Was Updated

Different state systems may have different update schedules. Therefore, check the filing date and current business status before relying on the result.

For important transactions, you may also consider obtaining certified copies or official certificates.

3. Enter the Correct Company Name or Number

A small spelling difference can lead to incorrect search results. Therefore, use the company’s legal name whenever possible.

If you know the entity or registration number, use it as well. It can make the US Company Search more accurate.

4. Be Careful With Third-Party Platforms

Some third-party platforms charge for company searches or detailed reports. While they can be useful, their information may not always be current.

Therefore, it is better to verify important information through the official state database first.

5. Check More Than Basic Registration Data

A company registration record is only one part of business due diligence. Depending on your purpose, you may also need to check credit reports, court records, intellectual property records, or SEC filings.

For overseas entrepreneurs, checking US company records can sometimes be difficult because each state has its own registration system. If you are also preparing to establish a US company, Ingstart provides US company registration, compliance, and tax-related services, which can help simplify the process and ongoing management.

US Company Search: Common Questions

How Can I Find a US Company’s Registration Number?

You can usually search for the company by its legal name through the relevant state database. Once you find the correct company, its entity or registration number is generally shown in the record.

How Can I Check Whether a US Company Is Legitimate?

A US Company Search can help you confirm whether a company has an official registration record and check its current status.

However, registration alone does not prove that a company is financially stable or trustworthy. For important business decisions, additional due diligence is recommended.

Is US Company Search Free?

Basic registration information is often available for free through state government websites. However, some states may charge fees for certified documents or copies.

Commercial credit reports and other detailed services may also require payment.

Can I Search for a Company Without Knowing Its State?

It can be difficult because there is no single public database covering all state-registered US companies.

If you do not know the state, you can first check the company’s legal name, address, website, or other available information to identify its likely state of formation.

How Can I Check for Legal or Financial Problems?

A basic company record may not show every legal or financial issue. Therefore, for a more complete review, you may need to check court records, bankruptcy information, credit reports, regulatory filings, or other public records.

Conclusion: Complete a US Company Search Carefully

A US Company Search is a useful first step when checking an American business. By reviewing state registration records and, when necessary, federal filings, credit reports, and other public information, you can better understand a company’s background before starting a business relationship. Most importantly, do not rely on a single source when a transaction involves significant business or financial risk. Combining official records with appropriate due diligence can help you make a safer and more informed decision.
