Identity verification is a standard, regulator-required step at licensed casinos, and claiming a no deposit offer can trigger it early. OnLuck Casino, licensed by the Curacao Gaming Control Board, may request proof of identity — a photo ID, proof of address or proof of payment method — after you activate your free reward or, more commonly, when you request your first withdrawal.
The check does not block your bonus: while documents are under review, you can keep playing your no deposit free spins and progressing the wagering requirement as normal. What it affects is the payout itself, since withdrawals are only released to fully verified accounts.
Prepare by uploading clear documents as soon as your account is created. Clear scans or photos normally clear review quickly, after which nothing stands between your winnings and your bank — every future cashout goes through without repeating the process.
