If a mailpiece cannot be processed by automated equipment because of its size, shape, or thickness, what is this mail commonly called?

• A. Nonmachinable mail
• B. Bulk mail
• C. Priority mail
• D. Registered mail

Answer: (A)

The main idea here is whether a mailpiece can move through the automated sorting equipment. If a piece doesn’t meet the equipment’s feeding and handling requirements due to its size, shape, or thickness, it’s labeled nonmachinable. That means it can’t be processed by the machines and must be handled manually, often with separate pricing or procedures. Think of a square envelope, a very thick card, or an oddly shaped item that won’t feed smoothly. These are classic examples of nonmachinable mail.

Bulk mail is about sending large volumes at discounted rates, not whether the piece fits automated equipment. Priority mail is a faster service tier with its own pricing. Registered mail adds tracking and security features. None of these define automation compatibility the way nonmachinable does.
