A confirmation letter is a correspondence sent to confirm details, like oral agreements, appointments, and job interviews. The letter can also confirm a reservation, a response to an invitation, receipt of a various items or services, or travel arrangements.
A Delivery Confirmation Number will tell you when and where that letter or package was delivered. For example, when we send out a USPS/Priority Mail letter or package, we include a Delivery Confirmation Number at no charge in the shipment confirmation email that we send out.
