How to address the envelope
Copy it exactly onto the envelope
Address the envelope to 302 E. Carson Street, 10th Floor, Las Vegas, NV 89101. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add your 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.
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 what the post office gives you
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.
The letter, written out
Copy the letter below onto one page, fill in the name and email on the account and, if you have one, an account or customer number, and it is ready for the envelope. Our template builds the same letter on screen.
