To verify a shelf corporation, pull its record yourself from the business search of the state where it was formed, confirm the formation date and an unbroken run of good standing, search the UCC index for liens, and get the seller’s identity, authority and promises in writing before any money moves. AgedCorporations.com’s checklist below takes each step in order and ends with the official business search for all 50 states.
Confirm the entity exists and its exact formation date
Start with the state, not the seller. Every state runs a public business search, and the table at the end of this page links the official one for each. Search by the exact legal name and, if the seller has given it, the file or filing number, which is the one identifier that never changes.
Delaware’s search shows, free of charge, the entity name, file number, incorporation or formation date and registered agent, and the Division of Corporations says its results include both active and inactive entities, so a name appearing in the results “is not an indication of the current status of an entity.”3 Other states work the same way. Florida’s Sunbiz search covers corporations, LLCs and limited partnerships, California’s bizfile search covers entities registered with the Secretary of State, and Nevada’s Secretary of State links its entity search from its business pages.101112
Check four things against the seller’s listing:
- The exact name. A near match is a different entity, with its own date and its own history.
- The entity type. A corporation and an LLC are sold and transferred differently, as transfer mechanics explains.
- The state of formation. An entity formed in one state and registered in another has two records; the formation date is on the home state’s record.
- The formation date. It must match the listing to the day. If it does not, stop.
Confirm continuous good standing (no dissolution, no reinstatement gap)
Good standing today is not the same as good standing every year since formation. Wyoming’s business search puts it plainly: the statement that a company is in good standing “simply notifies the public that all paperwork or fees required to form or maintain registration has been filed with the Secretary of State and is current.”4 It describes the present, not the past.
To see the past, open the entity’s filing history and read every line. You are looking for three things.
Every periodic filing, in every year. Count the annual reports, annual lists or biennial statements from formation to today. A missing year is a gap. In New York, a corporation or LLC that misses its biennial statement is shown as past due on the Department of State’s records and on any certificate of status it obtains.6
Any administrative dissolution, revocation or forfeiture. States end entities that stop filing or paying. Texas, for example, sends a notice of intent to forfeit the right to conduct business in the state when an entity does not meet its franchise tax filing requirements.13
Any reinstatement. Wyoming’s fee schedule has separate reinstatement filings for an entity dissolved for unpaid tax and for one dissolved for having no registered agent, and a reinstatement filing shows up in the history.5 An entity formed years ago, dissolved, and later reinstated is not continuously aged. Its record carries a break that any lender who reads it will notice, and a seller who describes it as seasoned without mentioning the break has told you something about how it does business.
Then order a certificate of good standing yourself, or insist that the seller deliver one dated within 30 days of closing. Wyoming issues them online at no cost; Delaware issues a certificate of status on request.53
Check for prior EIN, UCC filings, judgments and liens
A clean shelf entity, in the sense set out in what is a shelf corporation, has no federal tax account, no secured creditors and no court record. Each of those needs its own check, because the state business search shows none of them.
Prior EIN. None of the state searches shows whether an entity has an EIN, and the IRS does not publish them. Its guidance for a business that cannot find its own number is to check its bank, license applications and past returns, or to call the Business and Specialty Tax Line and request Letter 147C, “EIN Previously Assigned.”1 So the verification is contractual: the seller states in writing whether an EIN was ever issued. If one was, the entity already has a federal tax history. The IRS says a new EIN is needed, in general, when an entity’s ownership or structure changes, but its list of events requiring a new number for a corporation does not include a sale of shares, so a corporation sold by share transfer generally keeps its account.12 For an LLC the answer turns on how it is taxed and should be confirmed with the IRS or a tax adviser. Where the account is kept, the buyer must report the new responsible party, a step covered in transfer mechanics. The IRS also says nominees are not authorized to apply for an EIN, so an EIN obtained by a stand-in is a problem the buyer would inherit.1
UCC filings. A lender that takes a security interest in a business’s assets usually files a UCC financing statement with the state. The California Secretary of State describes its office as the central filing office for certain financing statements and other lien documents, and says filing serves to perfect a security interest in named collateral and establish priority.7 Colorado’s UCC page offers a public search by debtor name.8 Search the entity’s exact name, and its prior names if it has changed them, in the UCC index of the state of formation. A clean entity returns nothing.
Tax liens. The IRS files “a public document, the Notice of Federal Tax Lien, to alert creditors that the government has a legal right to your property.”9 Ask the seller to represent that no federal or state tax lien exists, and search the state and county records where a lien against the entity would be filed.
Judgments and lawsuits. Search the state court and federal court indexes for the entity’s name. An entity that never operated should have no court history. Any case, even a closed one, means the entity did something at some point, and the buyer needs to know what.
Identify the seller and their authority to sell
You are buying from whoever owns the shares or the membership interest today, and only that owner can transfer them. Before paying, get:
- the seller’s full legal name, state of formation and file number, and check that record too;
- the name and title of the person who will sign for the seller;
- a statement of who owns the entity’s shares or membership interest, and a copy of the stock ledger or membership record that shows it;
- confirmation that no one else, such as a lender or a former partner, holds a claim on those shares or interests.
A seller that refuses to identify itself before payment is a red flag on its own, discussed further on red flags. The closing documents need a real signature from a real owner, and anything less leaves you unable to prove you bought the entity at all.
Also ask what the seller has said about the entity. In 2024 the Michigan Attorney General alleged that a seller’s website marketed shelf companies as a means to deceive consumers and win favorable consideration in bids and equipment leasing; without any adjudicated finding, the seller agreed in an Assurance of Voluntary Compliance to stop selling Michigan entities and to remove website language promoting illegal or deceptive uses.15 A buyer whose seller markets entities that way should expect lenders and agencies to look harder at every entity from that source. The enforcement tracker follows this matter and others like it.
Demand the paper (articles, minute book, stock ledger, certificate of good standing dated within 30 days)
A properly kept shelf entity comes with its records. The delivery list should include:
- Articles. A copy of the articles of incorporation or articles of organization, stamped as filed, and every amendment since.
- Minute book. Bylaws or an operating agreement, the organizational minutes or consents, and any later resolutions.
- Stock ledger or membership record. For a corporation, the share register showing every issuance and transfer; for an LLC, the record of each membership interest.
- Share certificates or an uncertificated share statement, if the corporation issued any.
- Every annual report or list filed since formation, matching the state’s filing history.
- Certificate of good standing dated within 30 days of closing.
- Resignations of the current officers, directors or managers, effective at closing.
- Registered agent details and whether the agent’s fee is paid through the closing date.
Every document should match the state record. A minute book showing a name the state never recorded, or a filing the state does not show, is a discrepancy to resolve before paying. Florida’s amendment instructions note that the original incorporators cannot be amended, so the incorporator on the filed articles will not be the buyer, and that is expected.14
Get indemnity in writing
Every check above can miss something, which is why the purchase agreement has to carry the risk back to the seller. The seller should represent and warrant, at a minimum, that:
- the entity has never conducted business, opened a bank account, hired, contracted or held property;
- no EIN has been issued, or, if one has, its full history is disclosed;
- there are no debts, liens, judgments, tax liabilities or pending claims;
- every state filing has been made and every state fee paid through closing;
- the seller owns the shares or interest outright and has authority to sell.
The indemnity clause then makes the seller pay for any loss if a representation proves false, including arrears and penalties owed to the state for years before the sale. An indemnity is only as good as the party behind it, which is one more reason to know exactly who the seller is. The annual fees by state page shows what unpaid state charges can grow into, and how to buy a shelf corporation sets out the rest of the purchase agreement.
A 50-state SoS search table
Each link below opens the official business entity search for that state. Search the exact name, then open the entity’s detail page for its formation date, status and filing history. Some searches show the filing history free of charge, while others, such as Delaware, charge for status information and copies of filed documents.3
Questions readers ask
How do I check a shelf corporation's formation date?
Search the entity by its exact name or file number on the business search of the state where it was formed, using the official site listed in the table on this page. The state record shows the formation or incorporation date and the filing history. Do not rely on a certificate or screenshot the seller supplies; pull the record yourself and compare it with the seller's listing.
Can I find out whether an entity already has an EIN?
Not from a public search, because neither the states nor the IRS publish EINs. Ask the seller to state in writing whether an EIN was ever issued and to hand over any IRS notice if one was. After closing, an authorized person can ask the IRS for Letter 147C, which confirms a previously assigned EIN.
Is a certificate of good standing enough?
It is necessary but not sufficient. A certificate shows that required filings and fees were current on the day it was issued. It does not show whether the entity was dissolved and reinstated in the past, whether it has an EIN, or whether a lender has filed against it. Pair it with the full filing history and a UCC search.
What if the seller will not say who they are?
Walk away. The seller has to sign the stock transfer or assignment and the resignations, so its legal name and the name of the person signing will appear on the closing documents anyway. A seller who will not identify itself before payment is asking you to pay someone you cannot hold to its promises.
