Placement and Height

Mailboxes in New York 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.

A close up of an apartment number on a mailbox.

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.

Hands loading a box into a parcel locker.

Parcel Locker Ratio

In multi-family housing, there must be at least one parcel locker for every five mailbox compartments in new installations.

A row of mailboxes.

Mailbox Front

The face of the mailbox should be a minimum of 16 feet from the center line of the roadway and always at least 6 inches off any asphalt edge or shoulder, by New York State Highway Law.

Mailbox in the snow.

Snow Clearance

The mailbox and its support should allow for snowplow clearance, with a minimum of 48 inches of clear space under the mailbox and at least 2 feet back to the post from the face of the mailbox.

Centralized Mailboxes

In New York City, multi-unit residential buildings are often required by local building codes to install centralized mailbox systems (such as STD-4C mailboxes or cluster box units) in secure, accessible indoor locations, rather than curbside, to accommodate high-density living and enhance mail security.

Security Features

Some New York municipalities, including New York City, may require additional security features for mailboxes in multi-family or commercial buildings, such as locked vestibules, video surveillance or building staff oversight, to help prevent mail theft and unauthorized access.

A community of single family homes.

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.

A mobile home community

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.
An apartment community.

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.

A ring of dormitory housing.

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.

Fastest Growing Multi-Family Property Investments in New York

Multi-family housing continues to play a significant role in shaping New York’s urban landscape, with New York City standing out as a national leader in apartment development and investment. In 2024, Manhattan, Queens and Brooklyn all saw increases in multifamily transaction volume and investment, bucking national trends of slowing construction in other markets.

Other New York cities are also making significant strides in the multi-family sector:

  • New York City’s multifamily market is experiencing strong demand, with average rents rising and vacancies remaining exceptionally low (around 2.8%). Manhattan’s occupancy rate in stabilized assets reached 98.2% in late 2024, well above the national average.
  • Despite a national slowdown in new multifamily construction starts, New York City’s pipeline remains steady, with nearly 12,000 units under construction and another 35,000 in planning or permitting stages as of late 2024.
  • Investment activity in NYC’s multifamily sector surged, with dollar volume rising 14% year-over-year to $8.91 billion in 2024 and transaction counts increased as well.

Suburban areas around New York are also seeing increased interest in single-family rentals and build-to-rent communities, reflecting shifting preferences for space and amenities. Investors and property managers in New York’s top metros trust US Mail Supply’s mailbox solutions to match today’s tenant expectations and USPS standards.

Where can I buy mailboxes in New York?

USPS does not sell mailboxes directly. In New York, you can purchase USPS-approved mailboxes from suppliers like U.S. Mail Supply. Options include residential, commercial, wall-mounted, pedestal and centralized cluster units, all designed to withstand New York’s weather and security needs.

Any mailbox marked “Approved by the Postmaster General” and “U.S. Mail” meets federal USPS standards. For new installations or replacements, especially in multi-family or commercial buildings, mailboxes must comply with USPS STD-4C or F-series requirements. Always check with your local post office or postmaster for any additional community or building-specific regulations before installation.

Purchase a USPS-approved mailbox from a qualified supplier and install it according to USPS and local guidelines. For new construction or replacements, confirm the mailbox meets placement, height and size standards.

Custom mailboxes are permitted if they meet USPS standards for size, durability, visibility and construction. Before installing a custom mailbox, obtain approval from your local postmaster.

Curbside mailboxes should be placed 6–8 inches from the curb and 41–45 inches above the ground. Posts must be sturdy and buried less than 24 inches deep. For wall-mounted or centralized mailboxes (such as STD-4C or Cluster Box Units), follow USPS and ADA guidelines and consult your local post office for specific instructions.

Private carriers like UPS, FedEx and Amazon deliver throughout New York, but only USPS can use your official USPS mailbox. For non-postal deliveries, you may install separate delivery boxes or parcel lockers.

Businesses, universities and multi-family properties can establish custom mail delivery systems if they comply with USPS STD-4C and ADA regulations. Centralized mailbox systems must meet accessibility and security standards and approval from the local postmaster may be required.
