No there's no way to tell, global blocks are between the user and staff only, details are not shared with third parties. The block notice (that you get when you try to edit a page), should have a block id that they can use to refer to their block if they talk to staff via Special:Contact (eg, to appeal the block). It should also have the reason and length in it too.
