Last checked: October 2026
Sooner or later every online casino asks you to prove who you are. Most players run into it at the worst possible moment, right after a win, with a withdrawal waiting. Knowing what's coming, and getting it done early, is the simplest way to avoid a long delay or a voided win.
The industry calls this KYC, short for "know your customer." The details below come from the terms and help pages of 18 offshore casinos that take US players, checked in October 2026.
Why casinos ask
The casinos have a few reasons. They need to confirm your age and that you are who you say you are. They want to stop one person from opening several accounts to claim the same bonus again. And they need to know the card or wallet used to deposit belongs to you, so a stolen card can't be laundered into a "win." None of that is aimed at you personally, even when it feels that way.
When it happens
At nearly every casino we track, the documents are requested before your first withdrawal rather than when you sign up. You can usually play straight away and only hit verification when you try to cash out.
There are exceptions. BoVegas and Golden Lion require a verification phone call after your first deposit, and their terms say that if it isn't done, winnings can be voided and withdrawals cancelled. Golden Lion also asks players to renew their documents every six months.
What they ask for
Nearly every casino we track asks for a government photo ID, and the rest reserve the right to ask for documents. Beyond that, these are the documents you're most likely to need:
- A driver's license or passport, usually photos of the front and back, in color, with all four corners showing
- Proof of address dated within the last three months. A utility bill, bank statement or card statement is standard.
- Photos of the front and back of any card you deposited with. Casinos that ask for these usually let you cover the middle digits, and some let you cover the CVV.
- A selfie holding your ID. Vegas2Web requires it, and Sloto'Cash and several others ask for it in some cases.
- A signed form for card deposits. Bovada and Slots.lv use a Credit Card Verification Form for each card, and Bovada's help page says you need it before any withdrawal, even a Bitcoin one, if you deposited by card.
Some casinos can also ask where your money comes from, through bank statements or other proof of income. iNetBet, Kudos, Las Vegas USA, Vegas Casino Online, Miami Club, Red Stag, Sloto'Cash and Uptown Aces all reserve the right to ask.
Deadlines
Once a casino asks, the clock starts. Black Lotus, Jumba Bet, Lucky Creek and Mandarin Palace give you 14 days to send documents before the withdrawal is reversed back into your balance. iNetBet and Kudos give 10 working days, after which the account can be closed and the balance voided. Kudos wants documents within 24 hours on cashouts from free offers.
If you can't meet a deadline, tell support in writing before it passes. A message saying you're waiting on a utility bill is much better than silence.
How long it takes
The casinos' own estimates range from Sloto'Cash's "2 to 10 minutes" to up to five business days at Miami Club. Players report longer. Waits of a few days are common in recent reviews, and an independent test at the BoVegas and Golden Lion group in 2023 took up to 13 days. Verification usually happens only once, so after the first withdrawal later ones move faster.
What causes problems
Most verification trouble comes from a handful of mismatches:
- Name or address doesn't match. The name and address on your account, your ID and your proof of address should all be identical. A typo at signup can hold up a payout weeks later.
- Someone else's card. Depositing with a spouse's or parent's card is the classic mistake. Casinos require payment methods in your own name, and one Red Stag player reported a withdrawal refused for exactly this.
- A PO Box. A Miami Club player's verification stalled because the address on file was a PO Box, and Red Stag won't mail checks to one. Use your home address.
- Expired or unclear documents. Blurry photos, cropped edges or an expired license get sent back, and each round adds days.
- Edited documents. Don't alter a document in any way. Vegas2Web's terms specifically ban documents edited with AI tools.
- More than one account. Casinos match accounts by name, address, device and IP. Two accounts in one household can lead to winnings being voided, and player complaints at Golden Lion and Kudos describe exactly that.
How to make it painless
Sign up with your legal name and the address on your ID. Deposit with a card or wallet in your own name. Then upload your documents through the cashier as soon as you've made a first deposit, before you have a win waiting on it. Many casinos have a verification section in the cashier. At Sloto'Cash and Las Vegas USA it's under Withdraw, then Account Verification.
Take photos in good light on a flat surface, with the whole document in frame. Save copies of what you upload and of every message with support about verification.
Protecting your information
You're sending identity documents to a company outside the US, so be careful about how you do it. Upload through the casino's own secure cashier rather than by email when you can. Cover the card digits the casino says you can cover. Never send your Social Security number unless you understand exactly why it's needed. And if a message asking for documents arrives from an address that isn't the casino's, contact support through the casino's site before sending anything.
