Which USPS service provides proof of mailing, date, and time of delivery?

• A. Certified
• B. Express
• C. Registered
• D. Priority Mail

Answer: (A)

The correct answer is Certified mail. This service offers a reliable way to send mail with the assurance that the item was received. It provides proof of mailing through a receipt that is issued when the item is sent. Additionally, Certified mail includes tracking and a record of delivery, which specifies the date and time the mail piece was delivered. This makes it particularly useful for important documents where confirmation of receipt is necessary, such as legal notifications or official communications.

Other services, while they may offer their own unique benefits, do not provide the same level of proof of mailing and delivery details as Certified mail. For example, Express Mail provides expedited delivery but does not offer the same level of formal proof as Certified mail, while Registered Mail provides a higher level of security but is primarily focused on safeguarding valuable items rather than providing proof of mailing alone. Priority Mail, on the other hand, is designed for faster delivery and may include tracking but does not come with the same level of formal acknowledgment for mailing and delivery that Certified mail does.
