Unfortunately, for whatever reason, many online casinos (Bovada included) have a page that only summarizes the Bonus Terms & Conditions while a separate page lists them in full. The full page, which we will link again for your convenience.
Lists other Bonus Terms as well as more complete versions of the summarized terms above. 1.) The withdrawal of winnings is subject to Bovada verification procedures. This can include but is not limited to providing proof of address and government-issued identification. If we are satisfied that you have complied with the Terms, all Anti Money Laundering and fraud-screening requirements, and all rules relating to the Games and any related bonuses
This section is actually several terms wrapped up into one. Many online casinos would list some of these separately, but we will go ahead and unpack this whole thing as if they were listed individually.
Almost all online casinos will have some sort of verification procedures, and where Bovada says, "This can include...providing proof of address and government-issued identification…" almost all casinos will require both of these things upon making a withdrawal. Some casinos require you to send this information for multiple withdrawals, though most online casinos will only require it for your first withdrawal as long as you have done the subsequent withdrawals fairly recently.
