Parcel lockers are secure compartments within a mailbox unit designed to receive and store packages. They are typically larger than standard mail compartments, providing a safe and convenient way for residents to receive parcels that do not fit into regular mail slots. Parcel lockers ensure that packages are securely stored until the recipient can retrieve them.

How do parcel lockers work on 4C mailboxes?

In 4C mailbox units, parcel lockers are integrated into the overall design. Here's how they typically function:

1. Package Delivery: When postal workers deliver a package, they place it in a designated parcel locker.
2. Notification: The postal worker then places a key to the parcel locker in the recipient's regular mail compartment. This key is usually attached to a tag indicating the locker number.
3. Retrieval: The recipient uses the key to open the parcel locker and retrieve their package. Once used, the key typically remains locked in the parcel locker, preventing it from being reused until the postal worker retrieves it during the next mail delivery.

The size of the doors may vary depending on the specific design and configuration of the unit. However, standard tenant compartments in 4C mailboxes are typically 12 inches wide and 15 inches deep. This size ensures they can securely accommodate a typical day's worth of mail. Parcel locker doors are more oversized to handle packages, but the exact dimensions can vary based on the specific model and manufacturer.

The number of parcel lockers required in a 4C mailbox unit depends on the number of tenant compartments. The USPS generally recommends one parcel locker for every five tenant mail compartments. This ratio ensures adequate package space, reflecting the increasing volume of parcel deliveries in residential and commercial settings​.
