About ZIP Code 95712

Chicago Park sits in Nevada County's foothills between Colfax and Grass Valley. The 95712 ZIP code contains only PO Boxes—no street delivery exists for this community. The post office on Lower Colfax Road serves 340 boxes and handles mail for 49 local businesses.

This isn't a traditional town center. Homes and properties scatter across the surrounding hills, making PO Box service the practical choice for mail delivery. Residents come to the post office to collect their mail rather than receiving it at home. The single carrier route designation confirms that street delivery doesn't reach this area, making the PO Box the only delivery option for Chicago Park addresses.
