There are two addresses to mail your CO Form 104 depending on if you are including a payment or not -
If you are filing this return with a check or payment, please mail the return to:
COLORADO DEPARTMENT OF REVENUE
Denver, CO 80261-0006
If you are filing this return without a check or payment, please mail the return to:
COLORADO DEPARTMENT OF REVENUE
Denver, CO 80261-0005
That's almost the same address. Just the zip code extension is one digit different. It took me a second to see it was two different addresses!

This is an old thread from 3 years ago.
Are you referring to the comment above by AnthonyC? If so, those are 2 different addresses. Look closely at the last digit of the zip+4 code. One ends in 6 and one ends in 5 and would direct a mailing to a different department.
Those 2 addresses are what is shown at the bottom of the Colorado DR 0104 Individual Income Tax Return. Look at your actual return form DR 0104, page 4 at the bottom. Or see this blank one from the Colorado DOR website:

I used your address, no PO Box, street address, just the Colorado Department of Revenue, Denver CO, [removed] per your instructions. What I got back is a note on my envelope saying "INSUFFICIENT ADDRESS". Maybe you and Colorado should enlighten the Post Office? Cost me a couple of Stamps. PLEASE give me the correct, complete address!
It sounds like you should take this up with the Post Office.
The State of Colorado gives a list of addresses for filing various forms (look under "Commonly Used Zip+4 Codes" on this Colorado page).
Notice how none of these addresses has a street address.
