What is a regulation residential mailbox?

A regulation residential mailbox is a mailbox that meets the standards set by the United States Postal Service (USPS) for residential mail delivery. It typically must adhere to specific dimensions, materials, and placement guidelines to ensure safe and efficient mail delivery. Standard features include a secure locking mechanism, a front or side access door, and a design that allows postal workers to deliver mail without leaving their vehicles. Compliance with these regulations helps maintain uniformity and accessibility for all residents in a neighborhood.
