Cluster Mailboxes vs. NDCBU’s

Cluster Box Units (CBU’s) and Neighborhood Delivery and Collection Box Units (NDCBU’s) make for easy delivery to multiple residences at once, but since NDCBU’s were transitioned out in favor of cluster boxes, there are more rules about their use by the USPS. NDCBU’s design and security measures have become old and outdated, meaning new NDCBU’s cannot be purchased or installed unless it is to replace an existing or damaged unit.
