Mailbox Identification
How to Identify USPS Approved Mailboxes
Ensuring your mailboxes meet all the rigorous standards and testing to achieve "USPS Approved" status is an essential step prior to installation for USPS delivery. Look for the U.S. Mail Label or reference the USPS Postal Bulletin to find USPS Approved mailboxes and manufacturers.
USPS Guidelines
USPS Regulations Governing Centralized Mailboxes
Official USPS bulletins and federal guidelines for centralized mail planning.
See important information regarding customer and carrier accessibility and plan your CBU installation according to USPS standards.
NDCBUs are no longer supported for any continued centralized mail delivery service. All reasonable efforts must be made to identify all NDCBUs still in service and get them replaced as quickly as possible.
The Federal Register is not regularly updated – refer to the Postal Operations Manual and National Delivery Planning Standards Guide published by the USPS for current regulations for planning your mail center. Details related to a 2020 change in the mail compartment to parcel locker ratios can also be found here: 2020 Change to 4C Mailbox to Parcel Locker Ratio Requirements
The U.S. Postal Service requires a 1:5 ratio (one parcel locker for every five mailboxes) on mailbox installations.
