How to Check Information of a U.S. Registered Company - A Complete Guide

In today’s increasingly globalized world, more and more entrepreneurs and investors are turning their attention to overseas markets-particularly the United States, the world's largest economy. Whether it’s for business expansion, finding partners, or making investments, understanding the real background of a U.S. company is crucial. But do you know how to efficiently and accurately obtain this information? This article will walk you through the entire process and combine recent developments to help you master this essential skill.

1. Why Check U.S. Company Registration Information?

Before entering into any international business cooperation, conducting due diligence is a vital step. The U.S. maintains a highly transparent commercial environment with well-established systems for company registration and public disclosure. By accessing legitimate channels, you can evaluate a target company’s operational status, creditworthiness, and potential legal risks.

For example, in July 2025, a Chinese cross-border e-commerce company discovered through public records that its American supplier was facing multiple unresolved lawsuits. Based on this information, the company decided to delay the contract signing, thereby avoiding significant financial risk. This case demonstrates that mastering proper research methods not only improves decision-making but also helps mitigate risks effectively.

1. State Government Websites - The Primary Source

In the U.S., companies are registered at the state level. Therefore, your first step should be visiting the official website of the relevant state’s corporate affairs department. For instance, Delaware is one of the most popular states for incorporation due to its favorable business laws and mature judicial system. California and New York also host large numbers of registered businesses.

Take Delaware as an example Its Division of Corporations offers an online search tool at https//www.icis.corporations.delaware.gov/https//www.icis.corporations.delaware.gov/. Simply enter a company name to view key details such as registration status, formation date, and registered agent information.

2. Federal Tax ID EIN Verification

The Employer Identification Number EIN is a critical identifier used by U.S. companies for tax reporting. While the IRS does not publicly disclose all EINs, you can legally verify whether a company holds a valid EIN by requesting a W-9 form, which includes either the EIN or a Social Security number.

3. Business Credit Reporting Platforms - DB, ZoomInfo, etc.

Besides public sources, third-party business intelligence platforms like Dun Bradstreet DB and ZoomInfo offer valuable insights. DB has long been known for providing business credit ratings, payment history, and supply chain relationships. ZoomInfo, renowned for its powerful data collection capabilities, launched an enhanced business verification service in early 2025, helping companies assess potential partners more accurately.

These platforms usually require paid subscriptions, but they are a worthwhile investment for enterprises engaged in long-term international operations.

4. SEC EDGAR Database - For Publicly Traded Companies

If you're researching a publicly listed company in the U.S., the best source is the Securities and Exchange Commission SEC. Its EDGAR database https//www.sec.gov/edgarhttps//www.sec.gov/edgar allows free access to filings such as annual reports Form 10-K, quarterly reports Form 10-Q, and material event disclosures Form 8-K.
