And yet, in the US, you can have process servers publish a notice in a very specific law newspaper that only lawyers ever read, then claim that you couldn't reach someone who would never in their life read such a newspaper for decades simply to see if they've been served.

If this sounds ridiculous, it's because it is, and yet somehow, we still do it. What Sweden does sounds no different, except it's companies with millions of dollars who could actually afford to check these things.

As I mentioned, AFAIK that's only as a last resort once you've been unreachable via other means, which doesn't sound ridiculous at all. Is that not the case?

Could you point me to any description or source for this?

It doesn't describe any legal process I'm familiar with.
