KYC

Slimking verification: the pre-fight medical

Before your first withdrawal, the casino checks that you are who you say you are, that you live where you say you do, and that the money is yours. Clear documents get you through quickly.

Every boxer passes a medical before the bout. At an online casino it is called KYC, “know your customer”: a check of your identity, your address and your payment method. Expect it before your first withdrawal.

Documents usually requested

What it provesUsually accepted
IdentityPassport, photocard driving licence or national ID card, in date
AddressUtility bill, bank or card statement, or council tax bill from the last three months, showing your name and address
Payment methodA photo of the card (middle digits covered), a screenshot of the e-wallet account page, or a bank statement showing the deposits
Source of funds (larger amounts)Payslips, bank statements, or proof of savings or a sale

The casino says exactly what it needs for your account; this table is the common pattern, not its rules.

Upload so it passes first time

  1. Photograph the original, flat, in good light, with all four corners in view.
  2. Keep it readable: no glare, no blur, nothing cropped.
  3. Match your account: the name and address on the documents must be the ones you registered with.
  4. Send the full page of a statement, not a cut-out of the address.
  5. Upload through your account area, then tell support you’ve done it.

What slows a check down

  • Documents out of date, or a proof of address older than three months.
  • A different name on a card, for example a partner’s card used for a deposit.
  • A registered address that doesn’t match your documents after a move.
  • Incomplete answers to a source-of-funds request.

If verification drags on

Ask support for the status in writing and for a list of anything still outstanding. Keep every message. If the check stalls for weeks with nothing more asked of you, the complaints guide explains how to put it formally.

Questions and answers

When will I be asked to verify?

Usually before the first withdrawal, and sometimes again when deposits or withdrawals reach a higher level. You can often upload documents in advance from your account.

Can I send screenshots of documents?

Send photos or scans of the original document, with all four corners in view. Screenshots, crops and edited images are the most common reason for a rejection.

Is it safe to send my ID?

Upload documents only through the casino’s own account area or a channel support confirms in writing, never by replying to an unsolicited email or message. You can cover the middle digits of a card number; the first six and last four are usually enough.
