Which of the following is an example of an incorrectly named MRL Recipient?

• A. Suite 210
• B. John Doe
• C. P.O. Box 5
• D. Apt 1004

Answer: (D)

In MRL naming, the recipient must be identifiable for routing—either a real person or a valid mailbox/address. An apartment designation by itself doesn’t tell who should receive the mail or where to deliver beyond the unit, so it fails to identify the recipient. That’s why the apartment designation is the incorrect form. The other examples provide a clear recipient or a valid delivery endpoint: a person’s name is a direct recipient, and a P.O. Box gives a concrete routing destination. A suite designation can also be valid when tied to a full address, but on its own it’s typically part of a complete address rather than the sole identifier.
