Name the requested category
An identity document proves different facts from a utility statement or masked card image. Read the upload prompt and support message. If the reason is vague, ask which category failed, which field is missing and which file types or issue dates are accepted.
Inspect image and document quality
Show all required corners, avoid glare and blur, and keep text readable at normal zoom. Check expiry, issue date and whether screenshots are allowed. Do not edit, beautify or combine documents unless the portal explicitly permits it, because altered files can trigger another rejection.
Match the account profile
Compare legal name, date of birth and address character for character. A nickname, old address or omitted surname can create a mismatch. Ask support how to correct the profile instead of modifying a document. Payment proof should show ownership while masking fields the operator does not require.
Keep a safe submission record
Upload only through the official encrypted portal or verified support route. Save the request wording, submission time and receipt. Never provide a password, one-time code, complete card security number, wallet recovery phrase or unrelated full bank history.
