The USPS de-certified the older style NDCBU’s back in 1999 when they went to the new front-loading cluster box unit specification.
In isolated cases local postmasters will still allow their customers to use the older style NDCBU’s, particularly if they are replacing an existing unit that was damaged or is otherwise no longer functional. This is typical when multiple NDCBU’s are side-by-side, and one of them requires replacing.
There are also many private applications (non-postal) for NDCBU’s. One example is that trucking companies use them for their drivers to pick-up or drop off keys and paperwork. It is for these reasons that NDCBU’s are still being sold.
The newer style cluster box units are considerably different from the old NDCBU’s. This includes having a much thicker aluminum cabinet and doors; manufactured with much tighter tolerances, which means it is much more difficult to pry open doors; more weather resistance; stronger door locks; re-enforced postal control compartments; re-configured tenant compartments that more easily accommodate larger mail, such as magazines and catalogs; and the inclusion of secured outgoing mail compartments and parcel lockers for oversized packages. Obviously, mail carrier access is now from the front of the mailbox, as opposed to the back on the older style NDCBU’s as well. There are no USPS Approved rear-loading outdoor pedestal style gang mailboxes any longer. Shop our inventory of USPS approved cluster mailboxes.
The bottom-line is that if you wish to purchase the older style Neighborhood Delivery & Collection Box Unit, you must obtain local Postmaster approval prior to ordering. We do not take returns on NDCBU’s under any circumstances.
