How to address the envelope

The front of the envelope carries 6325 Spine Road, Boulder, CO 80301 and nothing else in the address block. Check the 80301 digit by digit before it goes in the post.
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.
Send it certified
