Warren is a small Massachusetts town where everyone needs a PO Box. This isn't by choice. Warren is designated a PO Box Only Zone, meaning there's no alternative mail delivery across its 12.2 square mile territory in Worcester County. The post office maintains 1,250 PO Boxes for 1,093 households, a 114% adoption rate that extends beyond local residents to serve surrounding rural areas.
Mail delivery in Warren follows a mixed pattern. Of the 316 street delivery records, 312 use rural carrier routes while just 3 use city routes. This rural delivery dominance reflects Warren's character: a town with a Main Street core surrounded by spread-out roads like Brimfield Road, Southbridge Road, and Coy Hill Road. General Delivery is also available, serving those without fixed addresses.
With a population of 2,549, Warren is unusually large for a PO Box-classified ZIP code. Only 4.5% of such ZIPs nationwide have populations over 1,000. The median age of 43.3 years and median household income of $92,558 indicate an established community. About 64% of homes are owner-occupied, and median home values reach $375,200.
Employment patterns are distinctive. Transportation and warehousing employ a significant portion of the workforce, while 39.2% work from home. The town maintains 38 business establishments employing 331 people. Street names like Knox Trail Road and Boston Post Road preserve the area's colonial history, while newer developments include Trudeau Drive and Heritage Drive.
Street names mix historic colonial routes (Boston Post Road, Knox Trail Road) with typical New England town streets (Main Street, Maple Street, Mill Street) and rural roads connecting to neighboring communities.
ZIP Code 01083 has 2,549 residents and 1,093 households (average 2.33 persons per household). The median age is 43.3 years, older than the state (39.9) and older than the nation (38.8).
