KYC is the step many players meet only when they try to withdraw, which is why it feels like an obstacle. In reality it is a standard legal requirement, and once it is done it rarely needs repeating. Knowing which documents casinos accept, what makes them reject an upload and when deeper checks such as source of funds appear lets you clear verification in one go. This guide explains the whole process, from the first upload to enhanced checks on larger accounts.
What is KYC at an online casino?
KYC stands for Know Your Customer. It is the process a casino uses to confirm that you are who you say you are, that you are old enough to gamble, that you live in a country it can accept, and that the money you play with is yours.
The duty comes from anti-money laundering law and from the casino's licence conditions. A casino that pays out without these checks risks fines or losing its licence, so legit operators apply them to everyone.
Which documents do casinos ask for?
Requirements vary slightly by licence, but most casinos ask for the same core set. Upload all of them at once if the casino allows it.
Names must match across all documents and your account. If you changed your surname, a marriage certificate or similar document may also be needed to link the two names.
- Proof of identity: passport, national ID card or driving licence, valid and not expired, with all four corners visible.
- Proof of address: a utility bill, bank statement or official letter showing your name and address, usually dated within the last 3 months.
- Proof of payment method: a photo of your card with the middle digits covered (first 6 and last 4 visible), or a screenshot of your e-wallet account showing your name.
- Selfie: some casinos ask for a photo of you holding your ID, or a short live check in the app.
- Source of funds: for larger deposits or wins, documents showing where your money comes from.
When does a casino run KYC?
Timing depends on the regulator. UKGC-licensed casinos must verify your identity and age before you can deposit or play. Many MGA and Curacao casinos let you play first and verify at the first withdrawal or when you reach a deposit threshold.
Even casinos that do not ask at registration can request documents at any time under their terms. That is why verifying early saves time: the check then happens while nothing is waiting, instead of while your first payout sits in pending.
Casinos also run automated checks in the background, matching your details against electronic databases, sanctions lists and self-exclusion registers. In many cases this electronic check passes without you uploading anything, and documents are only requested when it cannot confirm your details.
How do you complete KYC step by step?
The process takes about 10 minutes of your time if your documents are ready.
Keep the approval message or a screenshot of the verified status. If a later withdrawal is held for verification reasons, it is useful proof that your documents were already accepted.
- Open your account settings and find the Verification or Documents section.
- Make sure your name, date of birth and address in the account match your documents exactly.
- Photograph or scan each document in colour, flat, well lit and with all edges visible.
- Upload each file to the correct category (identity, address, payment).
- Wait for the status to change to approved, usually within 24-72 hours.
- If a document is rejected, read the reason and upload a corrected version rather than the same file again.
Why do casinos reject KYC documents?
Most rejections are about quality or mismatches, not suspicion. A blurry photo, a cropped edge, or a bill dated four months ago will be sent back.
Mismatches are the other big cause. If you registered with a shortened name, an old address or a typo in your date of birth, the documents will not match the account. Ask support to correct the account details first, since changing them yourself is often blocked after registration.
Screenshots of bills from a phone app are sometimes refused, while a downloaded PDF statement usually passes. Mobile phone bills and documents in your partner's name are commonly not accepted.
Expired documents are another frequent cause. An ID card that ran out last month will be rejected even if everything else matches, so check expiry dates before uploading.
What is a source of funds check?
Source of funds is an enhanced check in which the casino asks how you can afford your level of play. It is triggered by risk rules, typically higher deposit totals, large wins or a sudden jump in activity, and UKGC licensees in particular apply affordability and source of funds checks at fairly low thresholds.
Example: a player who has deposited 5,000 EUR in a month may be asked for 3 months of bank statements or recent payslips. Acceptable evidence also includes tax returns, a savings statement, or proof of an inheritance or property sale.
You can cover unrelated transactions on bank statements, but the casino must see your name, the account and your income. Delays here usually come from partial documents, so send the full set requested.
Do crypto casinos also require KYC?
Many crypto casinos ask for less information at sign-up, often only an email address. That does not mean verification never happens. Their licences, including Curacao licences under the LOK and Anjouan licences, still carry anti-money laundering duties, and the terms almost always allow the casino to request ID at any time.
In practice, checks are often triggered by larger withdrawals, unusual activity or a change of wallet address. Example: a player who deposits 0.01 BTC and wins the equivalent of 15,000 EUR should expect a request for ID and proof of address before that payout is approved.
Treat crypto casinos the same way as any other: keep your account details accurate, and have your documents ready before you play for larger amounts. If a casino ever asks you to pay a fee to complete verification, that is not normal practice and should make you suspicious.
Is it safe to send your documents to a casino?
Licensed casinos fall under data protection law, such as the GDPR for operators in the EU and UK, and many use specialist verification services rather than storing images in a support inbox. Upload through the secure account section, not by attaching files to live chat or regular email if a portal exists.
Before sending anything, confirm the casino's licence on the regulator's register. A casino you cannot verify is not one you should hand a passport copy to. CasiScore's table on this page lists casinos whose licences and payout records have been checked.
You can also add a watermark to your scans, such as the casino's name and the date, to limit misuse if a file is ever leaked. Most verification teams accept this as long as the text does not cover your photo or key details.
What happens if you can't pass KYC?
If you cannot provide the required documents, the casino will not pay out. Under most terms it returns your remaining deposits where it is allowed to and closes the account, but winnings may be withheld if the terms say so.
Never edit a document or submit someone else's. That is treated as fraud and leads to account closure and confiscated balances. If you are unsure whether you can meet the requirements, ask support before you deposit. The same check also protects you: it is part of how casinos enforce age limits and self-exclusion.
Myths vs facts
- Myth: A casino asking for documents is a sign it does not want to pay.
- Fact: KYC is a legal requirement for licensed casinos. A casino that never asks for anything is the bigger warning sign.
- Myth: Once you are verified, you will never be asked again.
- Fact: Basic KYC is usually one-off, but casinos can ask for updated documents when an ID expires, you change payment method or your play reaches enhanced check thresholds.
- Myth: You have to show your full card number.
- Fact: Casinos only need the first 6 and last 4 digits plus your name. Cover the middle digits and the CVV on the back.
Quick checklist
- Register with your full legal name and current address.
- Upload ID, proof of address and payment proof right after sign-up.
- Use colour scans with all four corners visible.
- Make sure proof of address is under 3 months old.
- Cover the middle card digits and the CVV.
- Keep recent bank statements ready in case of a source of funds request.
