Is it true that in order for someone to send a letter to the pseudo-state they have to write Turkey otherwise it won't be delivered?
It used to be true that you had to add "Mersion 10 TURKEY" at the end of your mail address if you wanted mail to be delivered to the north through Turkey because most of the mail was not delivered from the south to the north.
However, I have been using simply my address in the past 3-4 years and it goes to the Greek side, then the Greek side stamps a "Remember to use a Zip Code" sign on the letter and sends to the north. Most of the time, the mail does not get lost but occassionaly it does.
