If you can't deposit and already have another account at Blaze, even if it is closed, or get an error message about the "tax id": you can't have several accounts. Notify us on chat to request that the old account be reopened, and the new one closed. Chat: https://static.zdassets.com/web_widget/latest/liveChat.html?v=10#key=blazeltd.zendesk.com
If you just don't know where to click in order to deposit please check our article on the first steps at Blaze, https://help.blaze.com/hc/en-us/articles/4414506518929 .
