Yes, you can use a passport at a casino. U.S. casinos accept a valid passport as government-issued photo identification, and it satisfies every ID check you’re likely to encounter, from age verification at the door to the paperwork that comes with a large jackpot. A foreign passport works too, though it brings its own tax consequences if you win.
When You Actually Need to Show It
Walking onto a gaming floor often doesn’t require an ID check, though security can ask at any point, particularly if you look young. The moments that force the issue are the ones tied to money and records.
- Cashing out chips or vouchers at the cage, especially for larger amounts.
- Hitting a reportable jackpot. Starting in 2026, slot machine, bingo, and keno winnings of $2,000 or more trigger a W-2G tax form, and the casino can’t complete it without verifying who you are.
- Signing up for a player’s loyalty card, which asks for your name, date of birth, and sometimes a Social Security number.
- Any cash transaction over $10,000, which federal anti-money-laundering rules require the casino to record and report.
You can wander the floor without pulling out ID. The moment real money changes hands, your passport becomes essential.
Age Verification at the Door
Every casino in the country has to confirm you meet the minimum gambling age before letting you play. The age varies by state: most set it at 21, some allow 18, particularly at tribal casinos. If you’re near the cutoff, expect to be asked at the door and again at the tables or machines. A passport clears this check without issue because it carries both your photo and your date of birth.
Using someone else’s ID or a fake one to get around age rules is a criminal offense in every state. Casinos train staff to spot forgeries and often run IDs through electronic scanners that flag altered or expired documents.
Other IDs That Work
A passport isn’t the only option, and for most domestic gamblers it isn’t the most convenient one. Casinos accept several forms of government-issued photo ID:
- A current driver’s license from a U.S. state, territory, or Canadian province. This is the document most people actually use.
- A state-issued non-driver identification card.
- Military identification, including cards issued to active-duty service members and dependents.
- The U.S. passport card, the wallet-sized version issued by the State Department. It works the same as the passport book for domestic ID purposes.
A handful of states have started approving mobile driver’s licenses stored on a phone, but adoption is limited. Until your state’s gaming commission formally authorizes digital IDs, bring a physical document.
Expired or Damaged Passports
An expired passport creates problems. Casinos verify that ID is currently valid, and an expired document doesn’t meet that standard at most venues. The same goes for a cracked or delaminated passport where the photo or printed information is hard to read. If your passport is close to expiring, renew it or carry a backup before you visit.
The $10,000 Cash Threshold
Federal law requires casinos to file a Currency Transaction Report for any cash transaction over $10,000, whether buying chips, cashing out, or a combination that adds up to more than $10,000 in a single day.1eCFR. 31 CFR 1021.311 – Filing Obligations To complete the report, the casino must collect your name, address, Social Security number, and a government-issued ID number.2Financial Crimes Enforcement Network. Notice to Customers: A CTR Reference Guide Your passport handles the ID portion.
Casinos also file separate suspicious-activity reports for transactions of $5,000 or more that look unusual.3Financial Crimes Enforcement Network. Suspicious Activity Reporting Guidance for Casinos Breaking up transactions into smaller pieces to stay under $10,000 is a federal crime called structuring, carrying up to five years in prison and fines up to $250,000.2Financial Crimes Enforcement Network.

Jackpots and the W-2G
When you win above a reporting threshold, the casino has to issue a W-2G form to you and the IRS. For 2026, the threshold for slot machines, bingo, and keno is $2,000, up from a $1,200 figure that had stood for decades, and it will now adjust annually for inflation.4Internal Revenue Service. Instructions for Forms W-2G and 5754 Poker tournament proceeds and certain other winnings trigger reporting at $5,000 when the payout is at least 300 times the wager.5Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source
To complete the W-2G, the casino needs two forms of identification, at least one with a photo.4Internal Revenue Service. Instructions for Forms W-2G and 5754 A passport covers the photo requirement, and a signed W-9 can serve as the second piece. Without valid ID, the casino cannot pay the jackpot.
If You’re Traveling on a Foreign Passport
Winning money on a foreign passport changes the tax picture. Nonresident aliens face a flat 30% federal withholding rate on gambling winnings, higher than the 24% rate that applies to U.S. persons.6Internal Revenue Service. Publication 515 (2026), Withholding of Tax on Nonresident Aliens and Foreign Entities
Two exceptions matter. Winnings from blackjack, baccarat, craps, roulette, and the big-6 wheel are exempt from withholding for nonresident aliens, and no form is required to claim that exemption on those games.6Internal Revenue Service. Publication 515 (2026), Withholding of Tax on Nonresident Aliens and Foreign Entities Separately, if your home country has a tax treaty with the U.S. covering gambling income, you can claim a reduced rate or full exemption by filing Form W-8BEN with the casino before you collect.7Internal Revenue Service. Instructions for Form W-8BEN
For slot machines and other games where the exemption doesn’t apply automatically, the casino will withhold 30% unless you submit a completed W-8BEN claiming treaty benefits at the time of payment. Bring your passport and your home country’s taxpayer identification number. Reducing the withholding upfront is far simpler than filing for a refund later.
What Happens If You Forget It
You might still get through the front door. Past that, the lack of ID becomes a wall. The casino can’t legally pay a reportable jackpot, process a large cash-out, or enroll you in a rewards program without verifying who you are. In the worst version of this problem, you hit a life-changing jackpot and watch the casino hold your payout until you produce valid identification.
ID checks also enforce self-exclusion and banned-patron lists, so if you’ve placed yourself on a state’s self-exclusion registry the casino will flag your document and act accordingly.
Carry your passport, driver’s license, or another valid government-issued photo ID every time you visit, even if you’re only planning small bets. Jackpots don’t announce themselves in advance.
