Documents For Verification
Requests for address and payment verifications are frequently enabled on gambling sites for player identity checks, to ensure the player retrieving the winnings is the same person who gamble. Proof of payment method ownership is an essential step.

Casino users encounter verification in several forms, primarily via document uploads. Four common document categories are proof of identity, proof of address, proof of payment method, and selfie or liveness check REF4 /REF. Each document serves a distinct purpose in validating the player's eligibility to withdraw winnings.
What Verification is Asking For
Casino verification documents serve to prove the customer is who they claim to be, live where they claim, and own the payout method they have provided. In practice, these are:
- Proof of identity: Documentary proof that the player's name, date of birth, and photograph match the account details. This is usually a photo ID.
- Proof of address: Documentary proof that the provided address matches, such as a recent utility bill or bank statement.
- Proof of payment method: A document that proves ownership of the payment method, such as a photograph showing the name embossed REF3,4,5,6,7,8 /REF.
Why the Payment Method Matters
The provided payout method must be accessible to the player. It cannot be a partner's, for instance, as the funds need to be retrievable by the player themselves.
For bank cards, this can be a card photo with the customer's name and partial card details REF7 /REF. For bank transfers, a bank statement or online banking screenshot showing the customer's name and account number may be required REF11 /REF. For digital wallets, a screenshot showing the customer's name and email address used on the casino account is typically needed REF12,13 /REF.
What the Documents Usually Look Like
- Identity: An acceptable photo ID such as a passport, government-issued ID card, or driver's license REF5,9 /REF.
- Address: A recent utility bill, bank statement, or government-issued letter or document that includes the full address and is dated within the last 90 days REF6,10 /REF.
- Payment method: A bank card photo showing the customer's name, a bank statement showing the customer's name and account number, or a screenshot of a digital wallet account showing the customer's name and email address REF11,12,13 /REF.
Where Source-of-Funds Enters. Certain accounts may result in a request for a source-of-funds document, such as:
- A payslip
- A recent bank statement
- Recent tax returns [Additional sources such as proof of sale, business accounts, or winnings from other gambling may be accepted by some operators REF14 /REF.
Not all accounts require proof of source. The threshold for clearing this additional check depends on factors that are not publicly disclosed. The Friction Point. Verification can introduce friction, as it requires submitting sensitive personal documents and may involve multiple document types, including a selfie or liveness check REF8,12 /REF.
Minor discrepancies, such as abbreviations in the name, can trigger a second round of verification. It's best to use the exact name and address provided at signup, and to ensure the documents are unexpired and clearly legible. To avoid delays, submit the documents as requested, without any adjustments or enhancements made from the actual original. The Bottom Line: The Four Kinds of Check.
- Identity You are the person you say you are
- Address Your address is correct and current
- Payment Method You own the means of receiving the payout
- Source of Funds (where required) The next paid deposits are from proceeds
Given the multiple verification points, it's crucial to understand what each document is intended to prove and to ensure there are no discrepancies between the documents and the account information. Submission of the wrong type of document does create friction, especially with partial obscured card numbers, non-recent documents or not showing the full address. Delaying the player's payout by the need for re-submission hampers the gambling experience: a right way and a wrong way to do it.
