There are several reasons why your document might have been rejected:
Low quality, blurry or unreadable - We accept various formats including digital photo, scanned image, and PDF. Check everything is readable before you send the document. We do not accept print outs.
Expired or too old - Documents need to be valid, and a proof of address that is not an ID needs to be from the last 3 months.
Incomplete document or missing info - The document should not be cropped, and we need to see all four corners if possible. Make sure all essential information such as address/date/bank account number is visible.
Unsigned document - The back of your card will need to be signed
Name mismatch - Unless specifically requested otherwise, the documents must be in the account holder’s name.
