Mail Service


Mail delivery to Denver Energy Center is provided by the U.S. Postal Service via central mailrooms located in each Tower. Each mailroom is accessible via the concourse level in the service corridor.

Each tenant is designated a box number, to which all mail delivery will be made. Questions regarding US postal service mail delivery can be directed to the USPS by calling 303-313-5200.

Courier Drop Boxes

The Denver Energy Center has an Overnight Courier Drop Box Center for tenant use. The Center is located in the C-1 level of the 1625 Building by the freight elevator. Each box is provided for express mail only. If you have an item that needs to be shipped ground service, it will need to be dropped off at a store location.

Couriers and Deliveries

The Management office requests that couriers who bring mail or express mail abide by the Building’s delivery procedures. Mailbags and large package deliveries should not be brought through the revolving doors into the main lobby. The loading dock entrance should be used for these deliveries.

Delivery personnel must also use the freight elevator for deliveries requiring the use of a dolly or cart. Some tenants of the Building have couriers who bring mail or express mail to their offices at times other than regular delivery times. If after hour deliveries are to be made, they must be coordinated through the Management Office.

Delivery personnel must be authorized to enter the building by the appropriate tenant contact with prior written notification.
