A series of five-digit codes, sometimes extended by four additional digits, uniquely identifies specific geographic delivery routes within the Virginia city on the James River. This coding system facilitates efficient mail and package delivery by the United States Postal Service. For example, distinct sections of the city, from the northern Denbigh area to the southern downtown region, each possess a specific identifier within this framework.
These codes are essential for businesses and residents alike, ensuring accurate and timely receipt of correspondence and goods. Historically, their introduction revolutionized mail processing, moving from manual sorting to automated systems. Using accurate codes reduces delivery errors, improves service speed, and allows for streamlined logistical operations for businesses operating within and shipping to the area.
