Yes, it is possible. However we have in Germany for example additional postal
services (PIN AG) one could use locally and I doubt (while I do not know)
that TLAs or LEAs currently require them to collect such data. 

In case of letter usage, their are also RFID protection covers available,
so I would guess that these do not show that a letter contains an NFC

I also assume that for example local postal services, regardless where
they are located have no deal yet with international TLAs, LEAs to hand
over this date.

Last but not least, they could also been used as dead drops, locally.
