own adress on envelope for EC lab?

[Alessa]

Hi again,

I need to send my test sample to the EC lab in spain. I already had to pay for it, so the EC lab will know anyway where it came from. investigations would allow them to find out from where I did send the test sample. But in case my envelope gets intercepted, it would be harder for the police to find out where it came from, right?

Should I write my own adress on the envelope or not? Would it be suspicious if I don't?

International or within EU/EEA? I wouldn't be worried about a letter being sent within the EU, there're no customs controls and there's the postal secrecy.

I wrote another name and adress on the envelope... I didnt want to write my own adress and I didnt want it to be empty. I will get the result via email, so my adress shouldnt be important anyway.
