What does a certificate of mailing provide?

1. Proof of mailing

2. Proof of delivery

3. Proof of package weight

4. Proof of postage payment

The correct answer is: Proof of mailing

A certificate of mailing provides proof of mailing, which serves as official documentation that a specific item was sent through the postal service on a certain date. This certificate is particularly useful for customers who want to verify that they have indeed mailed a letter or package, as it includes details such as the date of mailing and the address of the sender. This form of documentation is especially beneficial in situations where the sender might need to demonstrate that they have fulfilled a mailing obligation, such as for legal documents, job applications, or important correspondence. The other options involve related concepts but don't accurately describe the function of a certificate of mailing. Proof of delivery pertains to confirming that an item has been received by the intended recipient, which is not covered by this certificate. Proof of package weight is not included in a certificate of mailing, nor is it its purpose. Lastly, proof of postage payment relates to showing that postage has been paid for the item, which is a separate process altogether from merely confirming that the item has been mailed.
