The addresses we hold
The address a cancellation letter to Siege needs, and every other address we hold, starting in Austin: copy the lines exactly and the envelope sorts itself.

How to address the envelope
Write the address as printed
One address block, copied whole: 1920 E Riverside Dr, Suite A-120, Austin, TX 78741. If any line differs from the card above, start the envelope again.
Add the return address
Top-left, your own name and address. A return address is what the post office needs to send the letter back if Siege has moved.
Certified mail, not a courier
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.
Keep the proof together
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
