USPS promotes Mailbox Improvement Week in May, encouraging installation of larger mailboxes for better package delivery.

USPS designates the third week of May as Mailbox Improvement Week, encouraging homeowners to upgrade to larger, jumbo mailboxes for improved package delivery. Alongside general maintenance, USPS suggests installing mailboxes with a bottom height of 3.5-4 feet from the road surface, contacting postmasters or carriers before installing or replacing mailboxes, and repainting rusted or peeling mailboxes. More information on jumbo mailboxes can be found on the USPS website.
