Modifying your personal information is a sensitive matter that requires increased security checks. To change your birth date you need to send a photo or a copy of a valid personal document to email@example.com. If you want to change your address, you should send the document to the same email address and you need to add a proof attesting to your current residential address. For that purpose, we accept utility bills, bank statements, home or vehicle insurance certificates and policies, certificates of residence. The proof has to be issued in your name and it may not be older than three months.
