How to address the envelope

  1. Use the address letter for letter

    Address the envelope to Filmi tänav 5, 10155 Tallinn, Estonia. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.

  2. Add the return address

    Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.

  3. Ask for certified mail

    Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.

  4. Keep the proof together

    Hold on to the letter copy, the receipt and the tracking page.
