The order matters less than the timing. Identity and address are often asked once and never again; source of funds arrives later, usually when the totals passing through an account cross a threshold the operator does not publish. A payout that has sat pending for days while nothing was requested is worth a question to support, because a check waiting on a document nobody asked for is the commonest cause of a stall.
Proof of address is the second, and the document that satisfies it is dated. A council letter, a bank statement or a utility bill from the last three months carries a name and an address on the same page, which is the whole point of it; a bill from last year does not. Screenshots of online banking usually pass where they show the bank's name, the account holder and the address together, and fail where a balance is all they show.
An answer that will not come has consequences worth knowing in advance. An account that cannot satisfy a source of funds request is usually frozen rather than closed, with the balance held until it can, and the deposits already made are normally returnable to their origin. That is the reason to deposit from an account in the same name from the start: every check further down the line reads more easily for a paper trail that began in the right place.
- A frozen account, and what it means for the balance
- Proof of address dated within three months
- Online banking screenshots, and what they must show
- Source of funds asks for paper, not an explanation
- Salary, pension and a house sale as ordinary answers
- Pending payouts where nothing was requested
