VerifySOS is a 50-state business-verification tool for credit and underwriting in trucking and commercial finance. One search merges Secretary of State registration, FMCSA/USDOT authority, OFAC sanctions, UCC liens, ownership, and county DBA filings into a single PDF packet.

How do I look up a business across all 50 states?

Enter the company name and its 2-letter state code (or a USDOT number) on verifysos.com. It searches the Secretary of State and FMCSA SAFER side by side, screens OFAC, and generates a verification packet PDF.

How much does VerifySOS cost?

There is a free tier, a Starter plan at $14.99/month (about 250 searches), and a Pro plan at $25/month with unlimited searches plus API access, UCC, and DBA.

Does VerifySOS show business ownership and officers?

Yes. Where a state publishes officers, members, or managers in its free public records, VerifySOS pulls them into the packet, separate from the registered agent, which is not the owner.

Nassau County DBA search — how to look up a fictitious business name (NY)

A DBA (doing business as) or fictitious business name is not a legal entity. It’s a filing that ties a trade name to a real owner · a person, an LLC, a corporation, or a partnership. In Nassau County, NY, that filing lives in the county clerk’s records, separate from the Secretary of State’s entity database. For credit underwriters, that separation matters: you can look up an LLC in Albany’s database and get a clean bill of health, but if that LLC is operating under a DBA that was never filed, or under a DBA with a lapsed renewal, you have a compliance and identity risk that no SOS record will catch.

A DBA is a county-level filing, not state-level

New York State does not maintain a centralized registry of assumed names or DBAs. Instead, each county clerk holds the records for fictitious business names filed in that county. If a business is operating under a trade name in Nassau County · say, “Bob’s Plumbing Solutions” as the DBA for a sole proprietorship or an LLC · that filing has to exist in the Nassau County Clerk’s office.

This is a critical blind spot for underwriters who rely only on Secretary of State searches. You can confirm that “Bob’s Plumbing LLC” is registered and active in New York, but you have no way to know from the SOS database whether Bob is also operating under three other DBAs, or whether any of those DBAs are expired. That’s why a county DBA search is a separate step in business verification, not an optional one.

What a Nassau County DBA record shows

When you locate a fictitious business name filing in Nassau County, the record will show:

· The trade name (the DBA itself) · The actual owner’s name and address (the individual, LLC, or other entity behind the name) · The start date of the filing · The expiration date (if applicable) · Whether the filing has been renewed

The owner’s address on a DBA record is often a home address, a PO box, or a mail-drop, and that discrepancy alone can be a red flag. If an LLC registered to a New York City office is operating under a DBA with a residential address in Great Neck, that mismatch doesn’t prove fraud, but it is a detail worth questioning during underwriting.

A DBA is typically valid for a set period (in New York, ten years from the date of filing, though rules can vary), and if the owner does not renew it before expiration, the filing lapses. A lapsed DBA does not automatically shut down the business, but it means the business is now operating without an active fictitious-name registration in the county. That is a compliance gap that can create title and liability issues, especially if the business is seeking credit or a loan against equipment or receivables.

How to search Nassau County DBA filings

The Nassau County Clerk’s office maintains searchable records of fictitious business name filings. You can access these records through the county clerk’s online portal by searching for a DBA name, the owner’s name, or both. The process is straightforward: enter the trade name, select the search date range if needed, and review the results.

Many underwriters will print or download the DBA record as part of their file, especially if the business is operating under a name that differs from its registered entity name. Keeping a copy of the DBA filing alongside the Secretary of State record and the UCC search is standard practice in credit work.

If the search returns no results, that is itself important information. A business may be operating under a DBA name with no official filing in Nassau County, which is a violation of New York law and a signal to dig deeper. Ask the borrower whether they have a filed DBA; if they claim they do and you cannot find it, that is a verification gap that has to be resolved before credit approval.

When a DBA matters for underwriting

A DBA becomes material in credit decisions when the business is applying for a loan or line of credit under the trade name, or when the collateral (equipment, accounts receivable, inventory) is titled or billed under the DBA name. If a lender is taking a security interest in assets, those assets need to be titled or referenced clearly so the lien attaches. If the collateral is titled under a DBA name that does not exist in county records, the lien position may be vulnerable.

Likewise, if you are verifying the owner’s identity for compliance purposes (KYC, beneficial ownership, OFAC), a DBA filing gives you a trail from the trade name back to the real owner. That linkage is essential for OFAC screening and beneficial-ownership diligence. A person or entity operating under multiple DBAs across counties can be harder to trace, and that difficulty itself is a compliance cost.

For UCC searches, a DBA also plays a role. UCC filings are indexed by the debtor’s legal name (the LLC or corporation name, or the individual’s name). If collateral is held under a DBA, you may need to search under both the legal name and the DBA name to ensure no prior liens are hidden.

DBA vs. legal entity: do not confuse them

Many borrowers use “DBA” and “LLC” interchangeably, but they are not the same. An LLC is a legal entity registered with the Secretary of State and has its own tax ID (EIN) and legal liability shield. A DBA is a trade name that sits on top of an entity. A person can be an LLC and still operate under a DBA. A sole proprietor with no LLC at all can file a DBA.

For underwriting, this distinction is crucial. If you are checking credit on “Bob’s Plumbing Solutions LLC,” verify that the LLC exists at the SOS level in New York, then search for any active DBAs under Bob’s name or the LLC’s name in Nassau County and any other counties where the business operates. If you find a DBA, pull it. If you find none, ask why not, or note the gap. Do not assume the business is legitimate just because it has an LLC; verify the DBA layer too.

Bottom line

A Nassau County DBA search is a county-level step that sits outside the Secretary of State process and the FMCSA/USDOT universe. It is a separate verify you have to do if the business is operating under a trade name. The filing shows you who the real owner is and whether the DBA is current or expired. If you skip this step because the business has a clean SOS record, you are missing a compliance and title risk that can surface during loan servicing or in a dispute. For any business in Nassau County operating under a DBA, pull the record, confirm the owner, check the expiration date, and keep it in your file.
