We both got our passports at the same time, but I couldn't help but notice they look completely different? Since we got them at the same time, it can't be that one is a new version and one is an old version, so it must be something else. But what exactly causes it? The fact I'm male and she's female? Or because she was born in Ireland and I wasn't? Or because this is my first Irish passport ever, and hers is just a renewal? Or maybe they just randomly ended up being done by different places, hers says "Dublin passport office" and mine says "passport service" so they are just randomly different depending on which place it ended up being made in? Sorry for the bombardment of questions lol but I'm just really curious why they're different
