Put the name records beside each other
A casino username is a login label. Compare the legal-name fields used for verification; they are the records support needs to check against your document.
Use the spelling the document actually carries
For a document with both Cyrillic and Latin fields, copy its Latin spelling exactly into your comparison. A familiar English spelling of a name can differ from the spelling on the issued document. Changing letters until the form accepts them leaves the underlying records inconsistent.
Ukraine's migration service explains that an issued Latin spelling can follow earlier documents through its document process. That is a reason to keep the actual passport spelling and any earlier variant together. It does not give a casino a universal rule for accepting every variant, and the same transliteration scheme should not be assumed across CIS documents.
If the document has no Latin field, ask which document or translation the casino accepts. Do not add translated letters to a photograph or replace the printed name. For example, Stake's identity help asks for documents in Latin international format. Check your casino's own accepted-document instructions before uploading.
Give support a comparison it can act on
Keep the message about the actual discrepancy. List the profile spelling, the spelling on the issued document and the payment-holder record in the private conversation. Say which field you believe needs correction, then ask support to confirm that diagnosis before changing it.
A useful request is: My verification notice refers to a name mismatch. Please identify the exact field that failed and the spelling you require from my issued document. My payment account belongs to me. Please confirm the approved correction procedure, the supporting document needed and whether my existing withdrawal remains open.
If support has not mentioned a name mismatch, change the opening to ask for the rejection reason. An unclear notice can concern a photograph, residence or a missing verification step. Repeatedly submitting the same spelling will not answer those questions.
Move on if the failed check concerns something else
A request for proof of address concerns residence. A selfie or video request concerns a separate identity step. Use the rejected-document workflow when support names a document defect; keep a chronology when it acknowledges the upload but has not made a decision.
Country of citizenship, the country that issued your document and current residence are different facts. A spelling correction does not settle whether the casino serves your location or accepts that document. Ask which of those fields is under review and keep your actual details consistent.
Once the name change is accepted, check the withdrawal status separately. An approved identity record does not show a transfer into your payment account. The withdrawal stage guide helps locate the next handoff.
