Why 4C wall-mounted mailboxes matter in Oceanside

Oceanside’s coastal environment and dense multifamily housing put a lot of stress on older mail equipment. Many communities are still using outdated wall boxes or improvised parcel areas that do not meet current USPS or accessibility standards.

Replace aging or non-compliant wall boxes with modern 4C mail and parcel modules
Upgrade improvised mail rooms and lobby setups to USPS-approved 4C equipment
Improve package security in buildings experiencing repeated theft or damage
Align older mail areas with current USPS and ADA reach, clearance, and hardware standards

Instead of hoping older mail rooms continue to pass inspection, you get a 4C installation designed for Oceanside’s climate, building layouts, and USPS expectations.

How Postal Systems coordinates 4C installations in Oceanside

Oceanside properties often need 4C work planned around tight parking, shared corridors, and active residents. We build projects around those realities so mail and parcel service continues with minimal disruption.

Recommend 4C mail and parcel configurations that fit your walls, rooms, and clearances
Plan work windows and phasing to keep access open for residents and carriers
Coordinate electrical and lighting considerations where parcel lockers are added
Schedule USPS inspection and respond quickly to any punch-list items

Our goal is a 4C mail and parcel setup in Oceanside that feels integrated with your building and is ready for daily USPS use on day one.
