A "Letter Receipt" is a document that confirms the delivery of a letter or package. It serves as proof that the recipient has received the item, often including details such as the date and time of delivery, the sender's information, and the recipient's signature. This is commonly used in both personal and business communications to ensure accountability. In many cases, a letter receipt is associated with services provided by postal services or courier companies. These organizations may offer tracking options, allowing senders to monitor the status of their delivery. This process enhances security and provides peace of mind for both senders and recipients.
