United States Postal Service

USPS Certification

USPS approval covers every letterbox or receptacle intended for the delivery of postage paid mail on any mail route. From the point of the manufacturer, this includes flag size, mailbox size, strength, and quality of construction. Generally, all mailbox interiors and door access are regulated to receive expected mail sizes. Residential curbside or rural mailboxes and post packages also must accommodate an installation height of 41-45 in. from the road surface to inside floor of the mailbox or point of mail entry (locked designs). A separate set of regulations is provided for all Commercial Mailboxes.

USPS-STD-4C

This specifications for Mailbox Security became mandatory on all new mailbox construction and major renovations. The USPS enacted standard revision 4C to enhance the resistance of centralized mailbox units to tampering and vandalism. The need for the new standard also arose from a 47% increase in flat mail and a 42% increase in parcels since 1985. This massive increase is largely attributed to growing consumer purchases from the Internet. The major change resulting from the standard 4C revision is in tenant mailbox size. While not universal, most vertical mailboxes are approximately 16 inches tall, 5 inches wide and 6 inches deep. These dimensions suit regular letters and post cards without a problem, but flat packages and periodicals must be contorted to fit within these inhibitive dimensions. 4C compliant mailboxes will measure exactly 3 inches tall, 12 inches wide and 15 inches deep, allowing periodicals and flats to lie down without rolling or folding, and increasing security with the smaller door size.
