Addressing mail to a specific unit within a larger residential building requires precision to ensure accurate delivery. The format typically includes the recipient’s name, street number, street name, followed by the apartment or unit number, then the city, state, and ZIP code. For example: John Doe, 123 Main Street Apt 4B, Anytown, CA 91234.
Correctly formatted addresses are vital for efficient mail processing by postal services and package delivery companies. Accurate addressing prevents delays, misdeliveries, and potentially lost correspondence or packages. Historically, the rise of apartment living necessitated standardized addressing conventions to distinguish individual residences within multi-unit dwellings.
