Geography and jurisdiction

The 06667 designation lies in Fairfield County, within the greater New York metropolitan area. As with many ZIP codes in this region, the area covered by 06667 may span more than one municipality and includes a mix of residential, commercial, and institutional addresses. The exact boundaries and the list of streets assigned to this ZIP code are determined by the USPS and can change over time.

Usage and administration

The USPS assigns 06667 for mail processing and local delivery within the specified postal area. The code is part of the broader Connecticut ZIP code system, which interlocks with neighboring codes for regional routing. Local post offices and carriers are responsible for managing mail within the 06667 area, including address validation, PO box services where applicable, and customer assistance.

History

ZIP codes were introduced in 1963 to streamline mail delivery. The 06667 code would have been established as part of ongoing USPS adjustments to regional coverage. Details about the exact date of creation and boundary changes are maintained by the USPS and may be updated as needed.
