How to Verify a Security Company's License (State-by-State, 2026)

In the United States, private security is regulated state by state. There is no single federal license for a security guard company — instead, roughly 41 states plus the District of Columbia each run their own licensing board, and a legitimate contract security firm must hold that state's company/agency license while, in most states, its officers hold individual guard registrations. Hiring an unlicensed provider isn't just risky; in many states it's a criminal act for the operator, and it can leave you — the client — exposed to negligence claims for putting an unqualified, uninsured operation on your property.

The good news: almost every licensing board publishes a free, public license-lookup tool. This guide shows you what to check, walks through the process, and gives you a state-by-state table with the licensing agency, the license names, the minimum insurance, and where to verify — for California and Illinois (our current markets) and the 20 largest US states we're expanding into.

Why licensing matters

A state license is the clearest single signal that a security provider is lawful and insured. Licensure bundles consumer protections that an unlicensed operator skips: background-checked ownership, mandatory liability insurance, minimum training standards, and a public disciplinary record you can inspect. Operating without a license is frequently a criminal offense — California makes unlicensed patrol operation a misdemeanor punishable by up to a $5,000 fine and a year in county jail, and most licensing states carry similar penalties.

The client-side risk is just as real. If you hire an unlicensed, uninsured company and one of its guards injures a visitor or uses excessive force, you can be pulled into the claim under theories of negligent hiring (you failed to vet the provider) and vicarious liability (the guard acted on your behalf). A valid license and a certificate of insurance are your first line of defense. This is exactly why our directory only lists licensed security companies, and why we built a dedicated license verification guide.

Two credentials: agency license vs. guard registration

Most states use a two-credential model, and both must be valid:

• The company/agency license authorizes the business to sell security services — California's Private Patrol Operator (PPO), Florida's Class "B" Security Agency, Illinois' Private Security Contractor Agency, New York's Watch, Guard or Patrol Agency, Texas' Class B Security Contractor.
• The individual registration authorizes a person to work as a guard — California's "guard card," Illinois' PERC card, Florida's Class "D," New Jersey's SORA registration, New York's Security Guard Registration.

A firm can hold a valid company license while deploying unregistered guards, or vice versa — so check at both levels. Note that a handful of states (Massachusetts, Michigan, Indiana, and Minnesota) license only the agency and do not issue a per-guard state credential; there, the agency license and its vetting is the credential to confirm. Armed officers always need an additional firearm permit on top of their guard registration — covered in our guide to armed vs. unarmed guards.

State-by-state: where to verify a license

Use the official .gov tool, never a third-party "verification" site. Direct verification links are in the Sources section at the end of this guide. Insurance/bond figures are the license minimums — a licensed firm should be able to prove at least this much.

For our two current markets:

• California: use the Department of Consumer Affairs license search (linked from BSIS), select license type "Private Patrol Operator," and confirm the status is current. Then check each officer's guard-card registration. Browse licensed security companies in Los Angeles and other California cities.
• Illinois: use the IDFPR license lookup — only active, non-expired licenses appear, so a "no result" can mean a lapsed license. See licensed security companies in Chicago.

How to verify a license, step by step

The mechanics are similar in every state:

1. Identify the licensing agency for the state where the work is performed (see the table above). If the state doesn't license companies, find the city license instead.
2. Open the official lookup tool — the state's own .gov site, not an aggregator.
3. Search by license number if you have it (fastest and least error-prone), otherwise the exact legal business name, and select the company/agency license type.
4. Confirm status, identity, and dates — the record should read Active/Current, match the legal name and address, and show a valid expiration date.
5. Check for discipline — suspensions, revocations, or public actions.
6. Verify the guards — confirm the officers assigned to you hold current individual registrations (and firearm permits if armed).
7. Confirm insurance — request a current certificate of insurance and match it against the state minimum in the table.

Reading a license record: what to check

When you pull up a record, four things matter — and several states have quirks worth knowing:

• Status must read Active or Current, not pending, inactive, suspended, revoked, or expired.
• Expiration date — some tools (Arizona's, for one) display "issued" even after a license has lapsed, so always read the date, not just the headline.
• Name and address match — the record should match the exact legal business name you're contracting with. In New York, agencies are searchable only by business name or unique ID, so have the legal name handy.
• Disciplinary history — look for suspensions, revocations, or public actions. In Illinois, only active licenses appear at all, so a "no result" is itself a red flag (it can mean the license lapsed).

The exceptions: no-license states, county models, and DC

A national guide has to account for the states that don't fit the standard model:

• States with no company license. Nine states license no security company at the state level: Colorado, Idaho, Kansas, Kentucky, Mississippi, Missouri, Nebraska, South Dakota, and Wyoming. Regulation there is municipal — Denver, St. Louis, Kansas City, and Louisville Metro each run their own schemes. Verify the city license and the firm's insurance directly.
• Pennsylvania's county model. Pennsylvania has no statewide company license; security and detective agencies are licensed county-by-county through the Courts of Common Pleas, and only armed personnel are state-regulated (via the State Police, Act 235). Treat PA like a local-licensing state for companies.
• Washington, D.C.'s split authority. DC divides the job: the Department of Licensing and Consumer Protection issues the business "Security Agency" license, while the Metropolitan Police Department's Security Officers Management Branch certifies individual officers (and the higher-authority Special Police Officers). Confirm both.

What's actually behind a license

A license is more than a certificate — it represents a set of requirements the company had to meet and must keep meeting. Understanding what sits behind the credential tells you why it matters. To hold a company license, most states require a background-checked owner and a qualified manager with documented industry experience (California, for example, requires the qualified manager to show years of guard and supervisory hours), minimum liability insurance or a surety bond, and adherence to training and record-keeping standards for the guards the company deploys. The license also creates accountability: a licensed firm has something to lose, because the board can suspend or revoke the license over misconduct, and that disciplinary history is public. An unlicensed operator has none of that structure — no vetted ownership, no guaranteed insurance floor, no training oversight, and no regulator you can complain to.

Verifying individual guards and armed permits

Confirming the company license is step one; in most states you should also confirm the people. Ask the provider for the guard registration numbers of the officers who will actually work your site, and check them on the same board's lookup — a valid company license doesn't guarantee every guard on the roster is currently registered and trained. In the states that license individuals (California's guard card, Illinois' PERC, Florida's Class D, New York's Security Guard Registration, New Jersey's SORA), the guard's status should read active and unexpired. If any officer will be armed, verify the separate firearm credential too — California's Exposed Firearm Permit, Florida's Class G, Illinois' Firearm Control Card, and so on — because armed authority is a distinct permit with its own training and expiration. Our armed vs. unarmed guide lists the armed credential for each major state.

What to do if a company can't prove a license

A legitimate provider answers "what's your license number?" without hesitation and is happy for you to verify it. Treat any of the following as a reason to walk away:

• Refusal or reluctance to give a license number, or "we're in the process of renewing."
• A number that doesn't match the legal business name on the state lookup.
• A record showing expired, suspended, or revoked status.
• Claiming a general business license or an LLC registration counts as a security license — it doesn't.
• Operating in a two-credential state while deploying unregistered guards.

If you're hiring in one of the no-license states (Colorado, Missouri, and the others), the absence of a state license is expected — but confirm the relevant city permit and, everywhere, get a current certificate of insurance. When in doubt, start from a vetted shortlist: every company in our directory of licensed security companies is listed against its state credential.

The four ways providers fake legitimacy

Simply asking "are you licensed?" isn't enough, because the ways a provider looks legitimate without being legitimate are specific and predictable. Watch for these four:

• The expired-but-displayed license. A framed certificate or a number on a proposal proves the company was licensed, not that it is now. Licenses lapse, get suspended, and get revoked — always check the live status and expiration date on the state lookup, not the paper.
• The borrowed number. An unlicensed operator cites a real license number that belongs to a different, legitimate company. This is why you match the license number to the exact legal business name and address on the record — a number that doesn't tie to the entity you're contracting with is a fraud signal.
• The licensed shell with unlicensed guards. The company holds a valid agency license but deploys officers who aren't individually registered or trained — cheaper for them, illegal, and your liability. In two-credential states, verify the guards, not just the company.
• The subcontracting blind spot. A licensed prime contractor wins your business, then quietly subcontracts your posts to a cheaper, sometimes unlicensed firm — so the guards on your site work for a company you never vetted. Ask directly whether any posts will be subcontracted, and require that any subcontractor be licensed and insured to the same standard, in writing.

Verifying a multi-state or national provider

Licensing is per-state, so a company operating across state lines needs a valid license in each state where it deploys guards — a California PPO does not authorize work in Texas or New York. When you're hiring a national or regional provider for multiple locations, verify the credential in every state that matters to you, not just the company's headquarters state. There's no true nationwide reciprocity; a legitimate multi-state firm holds a stack of state licenses and can produce each one. Ask specifically: "Which entity and license number covers the guards at my site's state?" A company that can't answer that cleanly for each location is either not properly licensed there or is subcontracting — in which case you need to verify the subcontractor too.

Credentials beyond the license

A state license is the baseline — legally required — but several additional credentials, while not licenses, signal a serious operator:

• Industry certifications — ASIS International's Certified Protection Professional (CPP) and related credentials indicate professional security-management competence at the company level.
• Federal registrations — a firm doing government work will have a SAM.gov registration and may hold facility clearances; relevant if your needs touch federal contracts.
• Insurance and bonding above the state minimum — a company carrying $1M–$2M when the state floor is a $5,000 bond is telling you something about how it operates.
• Training accreditation — membership in or accreditation by recognized industry bodies, and documented in-house training beyond the state minimum.

None of these replace the state license, but together they help you distinguish a professional firm from one that merely clears the legal bar.

How often to re-verify — and deeper due diligence

Licenses expire (typically every one to three years) and can be suspended between renewals, so verification isn't a one-time step. Re-check the license at renewal time, before signing a new contract, and if you ever have reason to doubt a provider's standing. For a larger engagement, go beyond the license: look for lawsuits or regulatory actions, check independent reviews for patterns (not one-off complaints), confirm the certificate of insurance is current, and ask for references you can call. The state lookup tells you a company is legally allowed to operate; this wider due diligence tells you whether it operates well. Our guide to hiring a security company walks through the full vetting process.
