How do you tell which AC adapter goes with which device?

Question

If the device says something like “DC-12V-IN”, will any 12V AC adapter with the correct connector work?

And why don’t they mark the adapter somehow so it’s obvious which device it goes with?

I usually get a strip of masking tape, loop it around the cable just below the plug part and write on it what it’s for to save that hassle.

You’ll tell yourself you’ll remember what is what but you won’t. Especially when you have several devices and their respective power adapters stored in the same area.
