This setup isn't uncommon for state capitals and administrative centers. Businesses use dedicated PO Box ZIPs to separate their mail from residential delivery systems. The zero registered population confirms what the delivery data shows: this ZIP exists purely for commercial and institutional mail routing. Trenton residents and most businesses receive their mail through neighboring ZIPs like 08691, which provides the actual street delivery for the area.
This ZIP code contains no street addresses. All 97 ZIP+4 records correspond to PO Box ranges rather than physical delivery locations.
