What triggers a document request

The four triggers

1. A withdrawal above a threshold. The threshold is almost never published and this is the most common trigger by a wide margin.
2. A change in pattern. A quiet account that deposits heavily and withdraws immediately reads as something to check, regardless of who is behind it.
3. A route mismatch. Depositing by one method and withdrawing to another is a standard flag everywhere in this industry.
4. Routine sampling. Compliance requirements unrelated to the individual account, which cannot be avoided by behaving differently.

Three of the four are partly controllable

Completing verification voluntarily before the first withdrawal moves the process from an urgent moment to an unhurried one. Withdrawing to the same asset and network the deposit arrived on removes the mismatch flag. Keeping a first withdrawal modest avoids the threshold, at the cost of making a second one later.

What is usually asked for

An identity document, a proof of address dated inside a recent window, and sometimes evidence of the source of funds where the amounts are large. The third is the one that takes time to satisfy, and it is worth knowing in advance that it exists rather than discovering it with a balance waiting.

What this means for choosing a site

The registration form is the least important part. The verification policy and the withdrawal clause are where the consequences live, and both are published before an account is opened.

More on how any of this works

The rest of how any of this works is below, each page built around one question rather than around a template. The reasoning behind the order of every list here is on the method page, the twelve entries are in the casino index, and the arithmetic that all of it rests on is in the learn section.
