The addresses we hold
One place for 1 Und 1's mailing addresses: the Montabaur delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.
Where the letter goesMailing address
1 Und 1Elgendorfer Straße 5756410 MontabaurGermanyThe Germany address on file for 1 Und 1. Postal code 56410.
How to address the envelope
Copy it exactly onto the envelope
Copy Elgendorfer Straße 57, 56410 Montabaur, Germany letter for letter. A wrong digit in 56410 is enough to send the letter on a detour.
Put your own address on it
Top-left, your own name and address. A return address is what the post office needs to send the letter back if 1 Und 1 has moved.
Buy the certified service
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 what the post office gives you
Hold on to the letter copy, the receipt and the tracking page.
