Three stages, three different parties
Stage one is the operator's own review. The operator's fraud checkers, AML team and audit duty review the payout request. By the time a payout reaches the operator's checking queue, the operator has already approved the original deposit: after all, the deposit celebrated a wager, and a win from playing at that casino can only be paid out of the original money deposited to the operator. But a first withdrawal does indeed mean the anti-money-laundering check, moved to the payout because it wants information the player only has at that stage, such as bank account details or utility bills. So stage one is often where a request will hang.
Stage two is the payment provider. This is a money-mover, nothing to do with a bank at all. The operator posts the cleared payout instructions, not yet the payment itself — and if the provider has its own security checks, those come in now. Some kind of notice will go to you, the player, the one who is ready to receive the money; but the operator will have already sent a message to the movement service, independent of that. If you can view the payout route and the operator claims it is already sent, the operator may mean stage two, not stage three. Check the operator's own message to you, not just what they say behind the scenes to you.
Only when the money-mover has cleared its own check is it ready for stage three. That is not an operator's bank: the operator's bank is used for deposits, for movement between the operator and the payment provider, and for cashflow backing — but that not the bit that sends your money. At stage three, the movement service has cleared the payout for posting, and posts it to your own bank in the US. But that posting happens in the bank schedule, not an operator's or provider's. Even though you want your money right now, publicly owned banks do not put payouts before holidays or weekends: they post on their normal runs, with their own calendars. Some offer an express posting no matter how weekday the posting date is, but that is not a guarantee that even the processing time can speed up. So the speed of your bank is dependent on the schedule of a bank, not an operator or a payout network.
What the cancel button does
The cancel function is there for players, not for operators. It puts that money back in play. It means that if you press cancel on a payout, you put the pulsing, cleared, unposted amount into your playable balance. At that point, you can wager the balance again before pressing the withdrawal button. After all, if you can leave it, it means it did not post to your bank: banks in the US cannot cancel or reverse a posting, only the institutions that post one. So cancel returns the request to the playable balance, where you can leave it or wager again.
That's why the cancel function is a safeguard for you, not an advantage for the operator. It means waiting for payouts goes wrong much less often than it would if there were no function at all. But it has to be available for just that reason, not as a feature for operators to ask you to use. The New Jersey Division of Gaming Enforcement published a Director's Advisory Bulletin on this in January 2021, concluding that current New Jersey rules prohibit an operator from soliciting or rewarding a "rescission" or a "cancellation" of a player's withdrawal request. This is not about players; this is about an operator's staff or an operator's systems asking or suggesting that you cancel a request, or rewarding you with something when you do. The Bulletin does not remove the cancel function; it just stops any operator from incentivising its use.
In particular, if you are playing in New Jersey, then that rule is in your favor. Even if you are a New Jersey player, the prohibition on paying rewards for cancelling or rescinding does not apply in a state that is not New Jersey. That is because New Jersey regulates its licenses, not the licenses of other states, and other state regulators set their own rules. Cancel is for you, not for the operator, and that is for your safety and protection, not the operator's profits.
The rule binds the licensees of the state that wrote it. It doesn't bind any other state's licensees — which is why you should always check your payouts against a known schedule, especially if the payout is taking longer than you expect. But whether New Jersey holds payout requests against you or not, you can always make sure that you check a state's advice or any advice from a regulator. Find out what the regulator has advised, and what you are entitled to. Operators are welcome to offer a customer-side cancel, refund or delay, but they are never entitled to ask you for them.
Why the first payout is the slow one
You won't have these troubles with a second withdrawal, or a fifth one. That's because the first withdrawal is the one that does all the checks that were not done at sign-up — and putting them at the first payout, not at sign-up, is not a design flaw. It's a security feature for you, the player, as a lot of them need information you generally do not have at the first contact you made.
A lot of the checks that take so long are the checks that you are over 21, a resident in the seven-licensing-state area and able to prove it, and in possession of the name and address the operator's systems have on file. This is not about the operator checking you; this is about the casino operator checking that you know and can access the bank in question. You might not know your mother's maiden name, so that is a common one. You will certainly know the name and address of the account, and be able to fetch the bank statement — but this isn't one of the documents you pick up casually, and the operator is generally entitled to be sure you can access it.
The checks are about identity at a casino level: proving you are who the system thinks you are. They are also about anti-money-laundering checks. Those are not the same. One is about you connecting your bank account to a gaming site; the other is about a gaming site looking into its own money-movement channels, and payment flows coming through your newly connected account. It could be a problem for you, or a problem across the operator's whole US payflow. While AML checks are about this for the operator, the operator is acting for you, the player, and the operator counts on you to help it along. In fact, the operator cannot complete the checks without you. So you might feel dragged through a twilight patch when you see the document requests — in fact, this is a trip that is sorted for you.
The operator should not ask you for the documents at the payout stage if they were not there at the sign-up. If you weren't asked for the ones that you know about, such as drivers' licenses, and you get asked later, it spells a problem. Hold on to that request, and ask why the documents were not there at the first contact. Either you did not provide the statements when you first registered, or the operator did not ask for them — and either scenario looks like things set to repeat in the next payout. The regulator should publish the amounts a gaming operator must check, and if a gaming operator asks you for documents it did not ask for at sign-up, they are worth recording and calling out.
What sits in the terms, not in the timeline
We have established that an unposted payout is still moving through a chain. The operator's system will not let you cash out with an open wagering requirement, so check that you are down to zero. Get the balance check by going to the zero. This does not depend on the payout time line in the states that regulate casinos; this is in the operator's terms.
If your playground is one of the seven states that licenses casinos, then you are a regulated party. Since you are a regulated party, the state regulator's timeline and terms apply. They apply to casinos licensed by that state. If you are in a licensing state, check the regulator's rules on payouts and the operator's terms. If there is a regulator's reply but no operator's, then the operator's terms are the thing in your state.
So each withdrawal goes on three legs. Stage one is the operator's work, stage two is the payment provider's. The third stage you know: that is when your own bank posts the money. If the operator says a money movement is not posted, but is still with a payment provider, then ask for the payment provider's document. If the provider never got the payout, then chase that up with the operator. If the provider did get it, and holds it with a delay, ask why. And if the provider got it and posted it, and you never saw it, then ask your bank. They have your bank details, and they have a posting trail: and they are the only ones on the hook, from the operator's payout to your checking account.
