Prior to USPS mailbox regulation changes in 2006, horizontal mailboxes were the standard for many large multifamily residential and business mail delivery applications. However, these time-tested mailboxes may now only be used in direct one-to-one replacements in facilities with U.S. Postal Service mail delivery. When initiating a replacement or renovation project - it is always a good idea to get the approval from your local postal authority before altering the mail system in your building; but in general, if your project is not disturbing the wall the mailboxes are already mounted in, then replacing old mailboxes with a product similar in style is typically acceptable. Any adjustment to the rough opening in the wall will require new STD-4C compliant mailboxes.
Florence Mfg 4B+ Horizontal 1400 Series mailboxes are still an excellent mailbox solution for any private delivery installation such as university dorms, internal business office distribution or a myriad of other private applications.
- As of October 6, 2006, USPS STD-4C compliant mailbox systems are mandatory on all NEW CONSTRUCTION and MAJOR RENOVATIONS.
- Mailboxes that are 4B+ compliant will only be considered USPS Approved if they are replacing existing mailboxes and as of 7/2020
- These mailboxes will require local USPS approval for use.
