How to Verify a Basketball Sportsbook's License in Your State

By Nina Castillo · Updated

About This Guide

Step-by-step guide to checking whether a basketball betting app holds a valid state license before you deposit a dollar.

Before you deposit a single dollar on a basketball betting app, the single most important thing you can do is confirm that the sportsbook actually holds a valid license in your state — not just a logo that looks official, but a real, verifiable authorization from a state gaming authority. We've signed up for and cashed out from dozens of apps, and we can tell you that skipping this step is where bettors get burned.

Why does a state license matter so much?

Sites operating without a US state license are illegal for US players and offer no regulatory recourse if a withdrawal is denied or an account is closed. That's the core issue: if an unlicensed operator decides to ghost you after you've built up a balance, you have nowhere to turn. No state regulator, no consumer protection, nothing. Compare that to a licensed book in, say, New Jersey — where sports betting is legal and live online, regulated by the NJ Division of Gaming Enforcement (DGE) — where you can file a formal complaint and expect a real investigation. To understand which states have legal frameworks in place, see our full breakdown at Basketball Betting Legality by State: What US Bettors Need to Know.

How do you actually check a sportsbook's license?

The right move is to go straight to your state regulator's official website and look up the current list of approved operators yourself. For example, New Jersey bettors can check the NJ DGE directly at nj.gov/oag/ge. Do not rely on an operator's self-reported claims — any site can slap a badge on its footer saying "licensed and regulated." The only source you should trust is the regulator's own published list. Here's a quick step-by-step process we follow every time we evaluate a new app:

  1. Identify your state's gaming regulator (e.g., NJ DGE, Pennsylvania Gaming Control Board, Michigan Gaming Control Board, New York State Gaming Commission, Colorado Division of Gaming, Arizona Department of Gaming, Tennessee Sports Wagering Advisory Council).
  2. Navigate to that regulator's official government website — look for a .gov domain.
  3. Find the section listing approved or licensed sports betting operators.
  4. Search for the sportsbook's legal entity name, not just its brand name.
  5. If the operator does not appear on the list, treat it as unlicensed regardless of what its website claims.

What are the red flags that suggest a sportsbook isn't properly licensed?

If a site accepts players from states where no legal framework exists — like Texas, California, or Florida, which do not have fully operational statewide legal online sports betting as of early 2025 — that's a significant warning sign. Similarly, if the app doesn't use geolocation to confirm you're physically inside a legal state before accepting a wager, something is off. Licensed books are legally required to run those location checks.

Does the license verification process differ for college basketball bets?

The licensing check is the same regardless of whether you're betting NBA or NCAA games, but college basketball does carry some additional state-specific rules worth knowing — certain states restrict prop bets on college players, for instance. Check out Can You Legally Bet on College Basketball (NCAA) in the US? for the specifics before you place your first bracket bet.

Once you've verified the license, what's next?

After you've confirmed the sportsbook is properly licensed in your state, the account creation process is fairly straightforward across all major operators. We walk through every field and verification step in our guide at How to Create a Sportsbook Account for Basketball Betting. Keep a government-issued ID and proof of address handy — licensed books are required to run KYC (know your customer) checks before processing any withdrawal, so getting those documents ready upfront saves headaches later.

Legality and bonus eligibility both vary by state, so always confirm your state's current status before registering or claiming any promotion. 21+ only. Gambling problem? Call 1-800-GAMBLER.
