My passport is 5 years old with 5 years validity remaining. The passport is a bit tatty and the picture was taken when I was 16, I'm now 21, have aged and look different (see photos) I have travelled to European Union countries on 6 separate occasions with my passport in this condition encountering only 1 problem on my most recent trip, to Slovakia where they hesitated for some time and then asked for my drivers licence. They let me through but it did worry me a bit. I am going to Croatia (which is not part of the EU) in just over 6 weeks and am now wondering whether to chance it with immigration in Croatia or send off for a new passport and hope I can get it in time. Do you think I need to renew my passport? Anyone had any past experiences like this?
