How to address the envelope
Copy it exactly onto the envelope
The front of the envelope carries Mainzer Landstraße 251, 60326 Frankfurt am Main, Germany and nothing else in the address block. Check the 60326 digit by digit before it goes in the post.
Put your own address on it
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Certified mail, not a courier
At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.
Keep the proof together
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.
