Often, the first time you initiate a withdrawal request on Luckland, you would be met with an identity verification request.
This is arguably not peculiar to Luckland, as most betting sites require a one-time submission of your documents to verify your identity.
This is often to confirm that you meet the minimum age requirement and to satisfy (if the case applies) that your nationality falls into the allowed category.
Aside from your ID documents, Luckland may also request credit card documents from you. These are aimed at preventing financial fraud.
Upon completing the first verification, subsequent withdrawals are processed without documentation request. However, unusually high withdrawal requests may need further documents.
