To check if a business has insurance, ask for a certificate of insurance, then call the insurance carrier listed on it to confirm the policy is active, the coverage types and limits are what the certificate claims, and the dates cover your project. A certificate on its own is a snapshot that can be outdated, altered, or issued under a policy that covers no one in practice. Independent databases run by state regulators, licensing boards, and federal agencies let you verify what the business tells you without taking their word for it.
Ask for a Certificate of Insurance
The standard proof-of-insurance document in the United States is the ACORD 25 form, a one-page certificate summarizing a company’s active policies. Any legitimate business will produce one on request before work starts. Vague answers or stalling about “not having it handy” is one of the clearest early warning signs.
Read the certificate carefully. The fields that matter:
- The insurance carrier name, meaning the company actually underwriting the policy, not the agent or broker who sold it.
- The policy number, which you’ll use to verify directly with the carrier.
- Effective and expiration dates covering the entire period of your project.
- Coverage types. General liability at minimum. Depending on the work, you may also need workers’ compensation, commercial auto, or professional liability listed.
- Per-occurrence and aggregate limits. Commercial general liability policies commonly carry $1,000,000 per occurrence and $2,000,000 aggregate. Lower limits may be inadequate for projects with significant injury or property damage risk.
- The certificate holder field, which should show your name or your company’s name, confirming the certificate was issued specifically for you.
Before you run any independent search, collect a few identifiers from the business. Companies often operate under a trade name different from the legal name on file with the state. The U.S. Small Business Administration notes that these “Doing Business As” names must be registered separately from the legal entity.1U.S. Small Business Administration. Register Your Business Ask for the legal name, the Federal Employer Identification Number (the nine-digit number assigned to every business entity), and any professional license numbers. Searching by legal name or FEIN is far more reliable than searching by trade name.
Call the Carrier to Confirm the Policy
A certificate is only as trustworthy as the person handing it to you. Fraudulent and altered certificates are a well-documented problem in commercial insurance, and verification takes about five minutes. Call the insurance company or agent listed in the “Producer” field, but look up the phone number independently rather than dialing the number printed on the document. Ask the carrier to confirm the policy number, the named insured, the coverage types, the limits, and the current status.
Signs a certificate may have been altered include handwritten changes to coverage limits, white-out marks over dates or policy numbers, and a carrier name you can’t find in any state licensing database. If anything looks off, ask the insurance company to send a fresh certificate directly to you rather than through the contractor. A real carrier will do this routinely.
Check State Workers’ Compensation Databases
Most states run a public database through their workers’ compensation board or industrial commission where you can look up whether a business carries active coverage. These portals let you search by company name or federal employer identification number and show the current carrier, policy number, and effective dates. This is the most reliable way to verify workers’ compensation because the data comes from regulatory filings rather than from the business owner.
A result showing “active” means the business is in compliance with the state’s requirement to cover workplace injuries. You may also see that a business has been granted an exemption, which generally means the owner has no employees and has filed paperwork certifying that fact. Exemption rules vary by state and some apply only to specific industries or corporate structures.
Watch for what the industry calls a “ghost policy.” This is a minimum-premium workers’ compensation policy that satisfies the paperwork requirement for bidding on jobs but covers no one in practice. If a contractor working under a ghost policy is injured on your property, there are no benefits to pay their medical bills or lost wages, and that liability can shift to you as the property owner.
To spot one, look at the covered employee count or payroll basis on the certificate. A policy listing zero employees or showing only excluded owners with a minimal premium is likely a ghost policy. That doesn’t necessarily mean the contractor is dishonest; many sole proprietors legitimately have no employees. It does mean you have no workers’ compensation protection if that person gets hurt on the job. Penalties for operating without required coverage vary by state and can include daily fines, stop-work orders, and criminal charges for repeat violations.
Check the Professional Licensing Board
Contractors, healthcare providers, real estate professionals, and other licensed occupations are monitored by state licensing boards that often track insurance and bonding alongside the license itself. Searching by license number or business name will show whether the entity has met the financial responsibility requirements for its license category. An active license is a meaningful signal, though not a substitute for checking the actual insurance details.
For construction work, that usually means verifying both liability insurance and a surety bond. The bond is a financial guarantee from a third-party company that the contractor will follow applicable regulations and complete the contracted work. If the contractor abandons a project or violates building codes, the bond provides a source of recovery. Contractors operating without required bonds or insurance face license suspension or revocation.
One gap in licensing board data: most boards track general liability and bonding but not professional liability coverage, also called errors and omissions insurance. General liability covers physical injuries and property damage. Professional liability covers financial losses caused by the professional’s mistakes, such as an architect’s design error, an accountant’s tax miscalculation, or a consultant’s flawed recommendation. If you’re hiring someone for their professional judgment rather than physical labor, ask specifically for proof of professional liability coverage. The licensing board won’t tell you whether it exists.
Check Federal Motor Carrier Records for Movers and Freight
If you’re hiring a moving company, freight carrier, or any business that transports goods commercially, the Federal Motor Carrier Safety Administration maintains a publicly searchable database called SAFER (Safety and Fitness Electronic Records).2Federal Motor Carrier Safety Administration. SAFER Web Search by the carrier’s USDOT number or MC number, both of which any legitimate carrier should provide without hesitation.
The Licensing and Insurance section of a carrier’s SAFER profile shows the type and amount of public liability and cargo insurance on file with the federal government.3Federal Motor Carrier Safety Administration. How Can I Check the Status of My Operating Authority Federal law requires motor carriers to maintain minimum insurance as a condition of their operating authority, and a registration remains in effect only as long as the carrier satisfies those requirements.4Office of the Law Revision Counsel. 49 USC 13906 – Security of Motor Carriers, Motor Private Carriers, Brokers, and Freight Forwarders For non-hazardous general freight carried in vehicles weighing over 10,000 pounds, the minimum is $750,000 in public liability coverage, and carriers hauling hazardous materials face substantially higher minimums.5Federal Motor Carrier Safety Administration. Insurance Filing Requirements
A carrier whose insurance filing has lapsed will show inactive or revoked operating authority. FMCSA updates these records frequently, so a current search gives a near-real-time picture of the carrier’s compliance. If a moving company can’t provide a USDOT number or their SAFER profile shows revoked authority, they are operating illegally.
Also check whether the carrier’s policy includes an MCS-90 endorsement. Federal regulations require this attachment on motor carrier liability policies, and it guarantees that the insurer will pay public liability claims even if the underlying policy language would otherwise exclude them.6Federal Motor Carrier Safety Administration. Form MCS-90 – Endorsement for Motor Carrier Policies of Insurance for Public Liability Its presence is a strong indicator the carrier is properly insured for interstate operations.
Confirm the Insurer Is Licensed and Financially Sound
Confirming that a policy exists is only half the equation. The insurer behind it needs to be financially capable of paying claims. An insurance company that is technically licensed but teetering on insolvency won’t help you when a six-figure claim comes in.
Two tools help. The National Association of Insurance Commissioners runs a public search where you can look up any insurance company and see every state where it’s licensed to operate, along with the lines of insurance it’s authorized to sell.7NAIC. Consumer Insurance Search Results – CIS If the carrier listed on the certificate doesn’t appear in the NAIC database or isn’t licensed in your state, the policy may be unenforceable regardless of what the certificate says.
Second, A.M. Best assigns financial strength ratings to insurance companies based on their ability to meet ongoing obligations. The scale runs from A++ (superior) down through lower grades. Look for carriers rated A- or better. A rating of B+ or below suggests the company may struggle to pay large or complex claims, and anything in the C range or lower should give you serious pause. Ratings are searchable for free on A.M. Best’s site. If a contractor’s carrier is unrated or carries a low financial strength grade, that policy is worth less than the paper it’s printed on.
Ask to Be Named as an Additional Insured
This is the step most people skip, and it matters more than any of the verification methods above if something actually goes wrong. A certificate proves the business has coverage. Being named as an additional insured on that coverage gives you the right to file a claim under the contractor’s policy if you’re sued because of their work. Without that status, you’re a certificate holder: you know the policy exists, but you can’t use it.
Say a contractor’s employee is injured on your property and sues you for unsafe conditions. If you’re an additional insured on the contractor’s general liability policy, that policy responds to defend you and pay any judgment up to its limits. If you’re only a certificate holder, you’re defending yourself with your own insurance or your own money.
Ask the contractor’s agent to confirm the endorsement in writing and send you a copy. The endorsement commonly used is the CG 20 10 form, which adds you as an insured for liability arising from the contractor’s ongoing operations. Some policies use blanket additional insured language that automatically extends coverage to anyone required by written contract, while others use a scheduled endorsement that applies only if you’re specifically named. Either approach works, but get written confirmation from the carrier. The words on the certificate alone don’t create these rights.
What’s at Stake if You Skip Verification
If an uninsured worker is injured on your property, many states treat you as the de facto employer for workers’ compensation purposes, making you responsible for medical bills and lost wages. Your homeowner’s insurance, the policy most people assume would step in, often excludes injuries to workers and contractors, particularly those without their own coverage. And if the contractor’s work injures a neighbor or a pedestrian, you can be named in the lawsuit as the property owner who hired the uninsured party, with defense costs and any settlement coming from your personal assets. A five-minute verification call is cheap insurance against all of it.
