How to address the envelope
Use the address letter for letter
One address block, copied whole: Groot Hertoginnelaan 201, 2517 ES Den Haag, Netherlands. If any line differs from the card above, start the envelope again.
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.
Buy the certified service
Certified mail is bought at the post office: hand the letter to a postal employee, keep the postmarked receipt, and follow the article number until the delivery shows.
Keep what the post office gives you
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
