Postal Service Practice Exam

Certified mail can be added to which types of service?

1. Standard and express

2. Priority and first class

3. Media and library

4. International and global

The correct answer is: Priority and first class

Certified mail is a special service that provides proof of mailing and delivery confirmation for certain types of mail. It is commonly used for important documents that require extra security and verifiability. The correct answer focuses on Priority and First Class mail, which are the primary classes of mail that can have certified services attached to them. Priority Mail, which includes faster delivery options and tracking, makes it ideal for sending important items securely. First Class mail, which includes letters and small parcels under a certain weight, can also benefit from certified services because it ensures the sender and recipient can track the mail and verify its delivery. Standard and Express, as indicated in the other option, do not apply because standard mail generally encompasses bulk or non-priority items that lack tracking or certified services. Additionally, Express Mail is a faster delivery service already providing its own tracking; while you can't add certified mail to it since it already has guaranteed delivery features. Media and library mail are specifically designed for specific content and are not eligible for certified service. As for International and global services, while they may have tracking through other means, the standard certified service is primarily tailored for domestic use within Priority and First Class categories, which makes the options tied to those classes the only valid choices for certified mail
