The delivery pattern here is unusual for an urban Connecticut location. While the ZIP maintains street delivery along Grand Street with 48 delivery records, the presence of 110 PO Boxes suggests this isn't a standard residential zone. The city carrier route designation confirms urban infrastructure, but the high ratio of PO Boxes to street addresses indicates this area functions more as a postal service hub than a typical neighborhood. Residents in surrounding parts of Waterbury with standard street addresses use the main 06702 ZIP code, which geographically encloses this smaller zone.
The entire ZIP code's street delivery concentrates on Grand Street, with all 48 records showing unit designations that indicate apartment buildings or multi-tenant commercial properties typical of urban Connecticut.
ZIP Code 06720 supports both business and residential activity. According to the Business Census (2024), there are 5 business establishments, employing about 191 people with an annual payroll of $33,697,000.
