Postal planning
Confirm the delivery method before choosing equipment.
Mailbox requirements vary by delivery application, project conditions, product configuration, and current postal guidance.
Coordinate early with the serving postal authority
Confirm the proposed delivery method and location before purchasing equipment or completing construction. Local review can affect placement, access, numbering, compartment schedules, carrier approach, and installation details.
Centralized mailbox projects
Apartment, community, commercial, and mixed-use projects may require centralized equipment such as 4C mailbox systems, cluster box units, or parcel lockers. Verify the exact model’s current approval status and installation documentation. A brand name or product family alone does not establish eligibility.
Residential delivery
Curbside and wall-mounted delivery have different placement, height, setback, carrier-approach, and mounting considerations. Confirm the serving office’s requirements before setting posts or drilling finished walls.
Documents to retain
- Current product model and configuration
- Manufacturer installation drawings
- Approved mailbox and parcel compartment schedule
- Site plan and accessible approach details
- Written postal coordination records
- Final quantities, numbering, locks, keys, and accessories
This guide is planning information, not an approval determination. Current requirements should be verified for the exact project and product.
