Every Secretary of State in the country maintains a searchable UCC index, and every one of them is accessible without payment. The tools exist. The question is whether you are using them before someone else does.
Five resources that provide genuine utility for a lien search on your own business, with practical guidance on what each does well and where each has limits.
1. Your State Secretary of State’s UCC Search Portal
This is the authoritative source. Whatever appears in your state’s filing office database is the legal record — and whatever does not appear there has not been officially filed, regardless of what a creditor claims. Most states provide online search access at no cost. California’s portal at the Secretary of State’s Business Programs Division, Illinois’s UCC search index, Oregon’s filing system, and South Carolina’s electronic retrieval tool are among the states with well-functioning interfaces. The National Association of Secretaries of State maintains a directory of all fifty state filing offices, organized by state, which serves as a reliable starting point for any jurisdiction.
The search is conducted by debtor name. For businesses, this means your exact legal business name as it appears in your formation documents. A search under a trade name or abbreviation may miss filings made under your formal legal name, and vice versa. Run the search multiple ways.
2. Nav Business Credit Reports
Nav aggregates data from multiple commercial credit bureaus and presents UCC filing information alongside your business credit scores. It is not a substitute for a Secretary of State search — it is a lagging indicator, not the authoritative record — but it is useful for a quick overview of what commercial lenders are likely seeing when they evaluate your business. The free tier provides a summary; the paid tiers provide more detail on the underlying filing records.
The most valuable use of Nav for UCC purposes is identifying filings that may have been made in a state other than your primary operating state. Because Article 9 determines filing location based on the debtor’s state of organization, not the state where business is conducted, a filing in Delaware or Wyoming may not surface in a search of your home state’s records.
3. Dun and Bradstreet’s Business Credit File
Dun and Bradstreet includes UCC lien information in its business credit file, which is separate from the Secretary of State’s records and operates on a different timeline. D&B retains lien data for up to eleven years from the date of inactivity — meaning a filing that has lapsed from the state’s active records may still appear as a historical item on a D&B report. This distinction matters when you are trying to understand why a lender is hesitant despite a clean Secretary of State search.
D&B offers a free basic report through its website. Requesting the report for your own business is a legitimate and common business practice, and it reveals the commercial credit profile that lenders see.
The D&B record and the Secretary of State record are two different systems maintained by two different organizations. Correcting one does not correct the other. Each requires a separate process.
4. PACER for Bankruptcy-Related UCC Searches
The Public Access to Court Electronic Records system is not a UCC search tool in the traditional sense, but it surfaces UCC-related disputes, secured creditor filings in bankruptcy proceedings, and adversary proceedings involving the validity of financing statements. If you are trying to understand whether a lien has been challenged or terminated through a court proceeding, PACER provides access to the underlying case documents. The cost is modest per page viewed, and many searches return no relevant results — but for businesses that have been through bankruptcy proceedings or creditor disputes, the record there can be informative.
5. Commercial Lien Search Services (CSC Global, CT Corporation)
Corporate service companies such as CSC Global and CT Corporation offer paid UCC search services that are comprehensive, jurisdictionally thorough, and formatted for professional use. These are not free. But for a business that is preparing for a sale, a significant financing transaction, or a legal dispute involving a UCC filing, the cost of a professional search report is small relative to the cost of discovering a missed lien during due diligence.
What these services do that state portals do not is search across multiple jurisdictions simultaneously, apply name variation logic, and produce certified results that carry legal weight in transactions. A lender or buyer who relies on a self-conducted search for a transaction of any significance is taking a risk that these services are designed to eliminate.
Running a lien search on your own business costs nothing except time, and it should happen before you apply for any financing, before you put your business on the market, and before you execute any transaction that requires clear title to your assets. What you find there belongs to you to address. A first call costs nothing and assumes nothing.
