How to Investigate a Company With Public Records
By The National Press Association editorial team · Last reviewed:
Start with the company's exact legal name. If it is public, search SEC EDGAR for its filings. If it is private, check the secretary of state's incorporation records. Then look for liens in state and federal records, and property deeds at the county level. Confirm each finding with a second, independent source.
Key takeaways
- Get the exact legal name first, and use the SEC's CIK number to pin down a public filer.
- EDGAR covers public companies. Most private companies do not file with the SEC.
- For private companies, start with the secretary of state's incorporation records.
- A missing or lapsed lien record does not prove a debt is gone.
- Public does not mean online, easy or free. Confirm everything with a second source.
Where do you start when you investigate a company?
Start with the exact legal name of the company. Write it down before you search anything else.
The SEC gives each filer a unique number called a CIK. A CIK narrows your results to the exact filer, so it helps when several companies have similar names [1].
Next, decide whether the company is public or private. That choice sets your path. A privately held corporation is not required to give information to the SEC, so EDGAR will not cover most private companies [2].
Build a short plan before you dig. List what you want to find:
- Every legal name, brand name and address you can confirm.
- The CIK, if the company files with the SEC. [1]
- The state of incorporation [1].
- The registered agent, if the company has one [2].
- Any liens, property and licenses tied to each name.
Plan for time and cost, too. A public record is not always online, easy to get or free [3].
How do you search a public company on EDGAR?
EDGAR is the SEC's database. It gives the public free access to corporate information. You can study a public company's finances and operations through the filings it makes with the SEC. [4]
To look up a company, type its name or ticker symbol into the search bar at the top of the SEC.gov home page [4].
The company's page shows key details. These include its name, address, telephone number, state of incorporation, CIK number, SIC code and fiscal year end [1]. Copy them into your notes.
The state of incorporation tells you which state to check next, because a state's secretary of state usually handles incorporation records [1]. [2]
Which EDGAR search should you use?
EDGAR has more than one search, and they work differently. Only EDGAR Full-Text Search indexes the text content of filings [5].
Other searches, including Company Search, index only filing header metadata [5]. A name that appears only in the body of a filing will not turn up in Company Search [5].
Use Company Search when you know the filer. Use Full-Text Search when you are chasing a name or a phrase through the text of filings [5].
Why check for amendments?
On EDGAR, a form type with "/A" added, such as 10-K/A, marks an amendment to the original filing [4].
Check whether the filing you are reading has been amended. If the two versions differ, note both and say which one you used [4].
How do you test what the company says?
The Reporters Committee advises you to compare a company's press releases with the reports on file with the SEC. [2]
Put the two side by side. Mark each place where they differ, then ask the company about each one [2].

What if the company is private?
Move to state records. A state's secretary of state is usually responsible for incorporation records [2].
A company can be incorporated in one state and do most of its business in another. That is not unusual by itself [2].
Access to full incorporation documents differs by state. In some states you may need to make a formal request, pay a fee or visit the secretary of state's office [2].
If you file formal requests often, keep a clear record of who you are and what you cover. You can see how a press credential can document your work. It does not give you any legal right to records.
Write down the registered agent if you find one. That is anyone or any business the corporation designates to receive its legal papers when it is sued [2]. Treat the agent as one more name to search.

How do you follow ownership and shell companies?
The Reporters Committee primer discusses incorporation records, registered agents and subsidiary lists in SEC filings [2]. It is worth keeping open as you work.
The same primer notes that a subsidiary list is sometimes not clearly labeled in the file name. You may have to find it among the unlabeled exhibits [2].
Shell companies need careful wording. Some have been abused in money laundering and tax avoidance schemes, but shell companies also have legitimate uses [2].
Out-of-state incorporation works the same way. It is not by itself a red flag [2].
Treat both as leads, not conclusions. Report what the records show, and do not say what they do not.
What do lien records show?
A lien is a claim tied to property. Two kinds matter most here: filings by lenders and sellers, and federal tax liens.
What is a UCC-1 filing?
When one business sells something to another on credit, a UCC filing is typically filed at the secretary of state's office [2]. That means one state office may hold both incorporation and lien filings.
The North Dakota Secretary of State calls the UCC-1, the initial financing statement, the first and most frequent public notice filing for liens [6].
Read a UCC-1 as a notice, not as proof of debt. Financing statements are not signed or enforceable documents. They only give notice that a security interest may exist [6].
North Dakota says a UCC-1 filing is effective for five years from the date of filing [6]. After five years it is considered lapsed and invalid if no continuation was filed [6].
So an absent or lapsed record does not show current debt [6]. The five-year figure comes from North Dakota. Check your state's law before you rely on it.
What is a federal tax lien?
The IRS files a public document, the Notice of Federal Tax Lien, to alert creditors that the government has a legal right to a taxpayer's property [7].
The IRS says the lien attaches to all business property and to all rights to business property, including accounts receivable [7].
A withdrawal removes the public notice, but the taxpayer is still liable for the amount due [7]. A missing notice does not mean the debt was paid [7].
What do property records show?
Deeds and titles to property are typically filed at the county level [3]. Start with the county where the company has an office or operates.
Property records are often online, but not always. A trip to the county registry may be required [3]. Call the office before you drive.
Information about property ownership may also come from local tax assessors' offices [3]. That information concerns who owns the property, not necessarily who lives there if it is rented [3].
Do not assume the search will be free or fast. Public records are not necessarily available online, easy to obtain or free [3].
When you pull a record, note the office, the date and the exact name you searched. That log helps you and your editor retrace each step.
What other records can fill gaps?
Business licenses can help. The Reporters Committee primer says a license is generally a public record and can be obtained from the issuing body [2].
Expect limits. Complaints and investigative materials held by state licensing boards are likely to be confidential [2]. Ask the board what it can release, and do not count on seeing a complaint file.
Bankruptcy filings can add detail. The same primer says bankruptcy court filings are available on PACER, the federal courts' electronic records system, for a fee [2].
What is a step-by-step checklist?
- Get the exact legal name. List every variant, brand name and address you can confirm.
- Decide whether the company is public or private. Most private companies do not file with the SEC. [2]
- If it is public, search EDGAR by name or ticker. Record the CIK, state of incorporation and fiscal year end [4]. [1]
- Use Full-Text Search to find the company's name inside other filings [5].
- Check each filing for an "/A" amendment [4].
- Compare press releases with the reports on file with the SEC. [2]
- Check the secretary of state for incorporation records [2].
- Search for UCC filings and federal tax liens. Read each as a notice, not a verdict [6]. [7]
- Check county records for deeds and titles. Confirm by phone whether they are online [3].
- Confirm each key finding with a second, independent source [3].
What are the limits before you publish?
Records tell you what was filed. They do not always tell you what is true today. Keep these limits in view:
- EDGAR will not cover most private companies [2].
- A lapsed or absent UCC record does not show current debt [6].
- A withdrawn tax lien notice does not mean the debt was paid [7].
- A shell company or an out-of-state incorporation is not proof of wrongdoing [2].
- Some records need a request, a fee or a visit [2]. [3]
Always try to confirm what you find with a second, independent source [3]. If a story makes a serious claim about a named person or company, talk to an editor or a lawyer before you publish.

Frequently asked questions
Where do I start when investigating a company with public records?
Start with the company's exact legal name and a short plan listing names, addresses, state of incorporation and registered agent. Then decide whether it is public or private. Public companies file with the SEC on EDGAR. For private companies, state incorporation records are a place to start.
Does EDGAR cover private companies?
Mostly no. The Reporters Committee says a privately held corporation is not required to give information to the SEC. For a private company, start with the secretary of state in the state where it incorporated, then check lien, property and licensing records.
What is the difference between EDGAR Company Search and Full-Text Search?
The SEC says only Full-Text Search indexes the text content of filings. Company Search and other EDGAR searches index only header metadata. Use Company Search when you know the filer, and Full-Text Search to find a name or phrase inside filings.
What is a UCC-1 filing and what does it tell a reporter?
A UCC-1 is an initial financing statement. It is a public notice that a security interest may exist. It is not a signed or enforceable document, so read it as a lead. North Dakota says it is effective for five years unless continued. Check your state's rules.
If I find no tax lien, does that mean the company paid its taxes?
No. The IRS says a withdrawal removes the public Notice of Federal Tax Lien, but the taxpayer is still liable for the amount due. A missing notice is not proof the debt was paid. Treat it as a gap and look for other records.
Are property records always online and free?
No. Harvard Law School Library's guide says public does not necessarily mean available online, easy to obtain or free. Deeds and titles are typically filed at the county level, and a trip to the county registry may be required.
