Requirements for Multi-Family Mailboxes in NC

Mailbox regulations in North Carolina are primarily governed by the United States Postal Service (USPS) standards, local municipal codes and specific requirements for multifamily dwellings.

It's essential to consult with local authorities or the local postmaster to comply with any additional regulations or standards specific to your area.

  • Placement and Height
    Mailboxes in North Carolina must be installed 6 to 8 inches back from the curb or road edge, with the bottom of the mailbox or mail entry point positioned 41 to 45 inches above the ground or road surface.
  • Address Visibility
    Each mailbox must clearly display the address number, with numerals at least 1 inch high, placed on the front or flag side for visibility.
  • Cluster Box Units (CBUs)
    For new construction or major renovations, USPS requires the use of STD-4C Horizontal Mailboxes or Cluster Box Units (CBUs). The highest tenant lock must be no more than 67 inches above the finished floor and the lowest must be at least 28 inches above the finished floor.
  • Parcel Locker Ratio
    In multi-family housing, there must be at least one parcel locker for every five mailbox compartments in new installations.
  • Mailbox Supports
    Mailboxes along public roads in North Carolina must be mounted on breakaway posts, such as 4×4 pressure-treated wood or small-diameter steel pipes. The North Carolina Department of Transportation (NCDOT) requires posts to meet safety standards and bend or break away on impact to reduce the risk of injury or vehicle damage.
  • Mailbox Placement
    Curbside mailboxes should be installed 41–45 inches above the road surface and positioned 6–8 inches from the edge of the pavement. Mailboxes must face the direction of traffic and clearly display the property’s address.
  • Locking & Parcel Delivery
    USPS-approved locking mailboxes are allowed as long as they include a slot large enough for standard mail and unfolded Priority envelopes. Centralized STD-4C systems in multi-tenant buildings must include one parcel locker for every five customer compartments.
  • ADA Compliance
    Centralized mailbox systems must meet ADA reach requirements. At least one tenant mailbox must be no higher than 48 inches from the finished floor, parcel lockers must sit at least 15 inches off the ground and master locks must fall between 36–48 inches.
  1. Site-Constructed Single-Family Developments
    Developers must coordinate with the USPS during the design phase, as centralized mail delivery with secure parcel lockers is the standard for new communities. If new homes are within one block of existing ones, they may adopt the same delivery method pending USPS review; otherwise, current centralized delivery standards apply.
  2. Mobile or Trailer Home Developments
    Permanent developments must have permanent lot assignments, public road maintenance and typically use centralized, curbside or sidewalk delivery as determined by USPS. Transient developments receive mail at a single USPS-approved location, with park staff handling internal distribution.
  3. Apartment Communities
    Use USPS-approved 4C centralized mailbox units with at least one parcel locker per five mailboxes, installed near main entrances and accessible to carriers. Outdoor units require USPS approval, must avoid streets or sidewalks and include a canopy with lighting and weather protection.
  4. Student Housing & Off-Campus Dormitories
    USPS delivers mail in bulk to a designated representative for distribution within dormitories, with no individual mailbox delivery provided. Dormitories—defined by shared living spaces—require early coordination with a USPS Growth Manager and may need named designees to accept mail.
