Florence NDCBU Private Delivery Mailbox Florence USPS Approved Locking CBU Mailbox

NDCBU's are NOT USPS approved and require special approval from your local Postmaster for USPS delivery. Florence F-series CBU units are the preferred option for USPS delivery.

Here's what you really need to know about NDCBU mailboxes: they are built for private use and NOT approved for USPS delivery. If you want to install an NDCBU (Neighborhood Delivery & Collection Box Unit) you will need the local Postmaster’s approval before your purchase—as a replacement or for new construction.

You may order an NDCBU mailbox if:

  • It will be used for private delivery
  • If you have explicit approval from your local Postmaster

Please get approval before ordering a new NDCBU! If you’ve got the green light and you're ready to order, please scroll down to view availability.

NDCBU’s vs. CBU’s

NDCBU’s are older style rear loading mailboxes the USPS de-certified back in 1999, meaning they are no longer approved for USPS delivery by default.

There are cases where local postmasters will allow you to use NDCBU’s for USPS delivery – particularly if you are replacing an existing damaged unit or somehow the old unit is no longer functional. You may be able to get approval when multiple NDCBU’s are side-by-side and one needs replacing.

What if I can't get approved for a new/replacement NDCBU mailbox?

You’ll want to look into our USPS approved cluster mailboxes (and decorative cluster mailboxes) – F-series units from Florence. The biggest difference is the newer models are front-loading. Plus, they are built tougher, with a thicker aluminum cabinet and doors, harder to pry open, are better resistant to weather and can accommodate bigger packages.
