With Endicia you can easily add the exact postage fees for extra services
from the US Postal Service to your letters and packages. This includes
Certified Mail, COD, Registered Mail, Return Receipt and Restricted Delivery.
You can add Return Receipt to one of the services above and the Postal Service will mail you proof of delivery. You can also add Restricted Delivery so only a specific individual is allowed to receive your shipment.
Please Note. Most of these services have restrictions and require special forms from the Postal Service, but the full postage will already be pre-paid on your mail. You’ll also need to present any letters or packages that use these services to a window clerk at the Post Office.
