A tribal gaming commission is the body a tribe uses to license and oversee gaming on its own lands, and how far its authority runs depends on the class of game. Under the Indian Gaming Regulatory Act (IGRA), the tribe alone governs class I, regulates class II under federal rules with National Indian Gaming Commission (NIGC) oversight, and may offer class III only under a compact with the state.
How IGRA sorts games into three classes
IGRA divides gaming into three classes, and every power a commission holds is defined class by class. The definitions come first because everything else hangs on them.
- Class I covers social games played for minimal prizes and traditional forms of Indian gaming played as part of tribal ceremonies or celebrations.
- Class II includes bingo, with or without electronic aids.
- Class III is every form of gaming outside classes I and II. NIGC rules place slot machines and their electronic facsimiles here, along with sports betting and parimutuel wagering on horse racing, dog racing or jai alai.
What the commission controls in each class
The commission's control is complete in class I, shared with federal rules in class II, and conditional on a state compact in class III.
Class I gaming sits within the exclusive jurisdiction of the tribe and outside IGRA's provisions altogether. There is no federal approval step and no state role.
Class II gaming stays under tribal jurisdiction but is subject to the federal statute's provisions. This is where most of a commission's licensing work happens. The tribe must issue a separate licence for each location where class II games are run, and it must license primary management officials and key employees with prompt notification to the NIGC.
Class II is also the route to greater independence. A tribe that has run class II gaming continuously for not less than three years, including at least one year after October 17, 1988, may petition for a certificate of self-regulation.
Class III gaming, which includes slots and sports betting, is lawful only when conducted under a Tribal-State compact in effect. Without one, the commission has nothing in class III to regulate.
Where the NIGC and state compacts sit
The NIGC sits above the commission for class II and class III, and the state sits beside it for class III only, on the terms the compact sets. This is the arrangement as federal law and NIGC rules read in October 2026.
Before class II or class III gaming can run, the tribe submits its gaming ordinance to the NIGC Chair for approval. That submission must include the tribe's procedures for background investigations on key employees and primary management officials, so the commission's own vetting process is reviewed at federal level.
A compact can reshape the commission's position in two concrete ways. It may provide for the allocation of criminal and civil jurisdiction between the state and the tribe, and it may let the state assess the tribe to cover regulation costs. Both are terms IGRA places inside the compact, so they vary from one tribe and state to the next.
| Class | What it covers | Tribal commission | NIGC | State |
|---|---|---|---|---|
| I | Minimal-prize social games, ceremonial games | Exclusive jurisdiction | No role under IGRA | No role |
| II | Bingo, including electronic aids | Licenses each location and key staff | Approves ordinance, receives licence notices | No role |
| III | Slots, sports betting, all other gaming | Regulates within the compact | Approves ordinance | Party to the compact |
Tribal gaming commission phone number: reaching the right office
There is no single national phone number, because regulation is organised tribe by tribe: each tribe adopts its own ordinance and issues its own licences. The office to contact is the commission of the tribe that operates the casino in question.
For a question about a specific venue, such as a licensing or conduct issue, start with that tribe's commission. For a question about whether a tribe's class II or class III ordinance has federal approval, the approving authority is the NIGC Chair. Where class III gaming is involved, the state's role, if any, depends on what that tribe's compact provides.
Questions and answers
What does a gaming commission do?
On tribal lands, the commission licenses and oversees gaming under the tribe's own ordinance. For class II it issues a licence for each gaming location and licenses key employees and primary management officials; for class III it works within the terms of the Tribal-State compact.
What agency investigates gambling on tribal lands?
Background investigations of key employees and primary management officials are run under the tribe's own procedures, which the NIGC reviews when it approves the gaming ordinance. Where a compact covers class III gaming, it may also allocate criminal and civil jurisdiction between the state and the tribe.
What qualifications do I need to work in tribal gaming?
Requirements are set by each tribe, but federal law shapes the senior roles: primary management officials and key employees need a tribal licence, and the tribe notifies the NIGC promptly when it issues one. Those licences follow the background-investigation procedures in the tribe's approved ordinance.
