D040 Delivery of Mail

Summary

D041 describes the standards for letterboxes or other receptacles for the deposit or receipt of mail. It also contains the standards for curbside mailboxes.

1.0Basic Standards

1.1Authorized Depository

Except as excluded by 1.2, every letterbox or other receptacle intended or used for the receipt or delivery of mail on any city delivery route, rural delivery route, highway contract route, or other mail route is designated an authorized depository for mail within the meaning of 18 USC 1702, 1705, 1708, and 1725.

1.2Exclusions

Door slots and nonlockable bins or troughs used with apartment house mailboxes are not letterboxes within the meaning of 18 USC 1725 and are not private mail receptacles for the standards for mailable matter not bearing postage found in or on private mail receptacles. The post or other support is not part of the receptacle.

1.3Use for Mail

Except under 2.11, the receptacles described in 1.1 may be used only for matter bearing postage. Other than as permitted by 2.10 or 2.11, no part of a mail receptacle may be used to deliver any matter not bearing postage, including items or matter placed upon, supported by, attached to, hung from, or inserted into a mail receptacle. Any mailable matter not bearing postage and found as described above is subject to the same postage as would be paid if it were carried by mail.

1.4Clear Approach

Customers must keep the approach to their mailboxes clear of obstructions to allow safe access for delivery. If USPS employees are impeded in reaching a mail receptacle, the postmaster may withdraw delivery service.

2.0Curbside Mailboxes

2.1Manufacturer Specifications

Manufacturers of all mailboxes designed and made to be erected at the edge of a roadway or curbside of a street and to be served by a carrier from a vehicle on any city route, rural route, or highway contract route must obtain approval of their products under USPS Standard 7, Mailboxes, City and Rural Curbside. To receive these construction standards and drawings or other information about the manufacture of curbside mailboxes, write to USPS Engineering (see G043 for address).

2.2Custom-Built
Mailbox

The local postmaster may approve a curbside mailbox constructed by a customer who, for aesthetic or other reasons, does not want to use an approved manufactured box. The custom-built box must generally meet the same standards as approved manufactured boxes for flag, size, strength, and quality of construction.

2.3Address Identification

Every curbside mailbox must bear the following address information:

a. A box number, if used, inscribed in contrasting color in neat letters and numerals at least 1 inch high on the side of the box visible to the carrier’s regular approach, or on the door if boxes are grouped.

b. A house number if street names and house numbers have been assigned by local authorities, and the postmaster authorizes their use as a postal address. If the box is on a different street from the customer’s residence, the street name and house number must be inscribed on the box.

2.4Owners Name

The mailbox may bear the owner’s name.

2.5Advertising

Any advertising on a mailbox or its support is prohibited.

2.6Mailbox Post

The post or other support for a curbside mailbox must be neat and of adequate strength and size. The post may not represent effigies or caricatures that tend to disparage or ridicule any person. The box may be attached to a fixed or movable arm.

2.7Location

Subject to state laws and regulations, a curbside mailbox must be placed to allow safe and convenient delivery by carriers without leaving their vehicles. The box must be on the right-hand side of the road in the direction of travel of the carriers on any new rural route or highway contract route, in all cases where traffic conditions are dangerous for the carriers to drive to the left to reach the box, or where their doing so would violate traffic laws and regulations.

2.8More Than One Family

If more than one family wishes to share a mail receptacle, the following standards apply:

a. Route and Box Number Addressing. On rural and highway contract routes authorized to use a route and box numbering system (e.g., RR 1 BOX 155), up to five families may share a single mail receptacle and use a common route and box designation. A written notice of agreement, signed by the heads of the families or individuals who want to join in the use of such box, must be filed with the postmaster at the delivery office.

b. Conversion to Street Name and Number Addressing. When street name and numbering systems are adopted, those addresses reflect distinct customer locations and sequences. Rural and highway contract route customers who are assigned different primary addresses (e.g., 123 APPLE WAY vs. 136 APPLE WAY) should erect individual mail receptacles in locations recommended by their postmasters and begin using their new addresses. Customers having different primary addresses who wish to continue sharing a common receptacle must use the address of the receptacle’s owner and the “care of” address format:

JOHN DOE

C/O ROBERT SMITH

123 APPLE WAY

Customers having a common primary address (e.g., 800 MAIN ST) but different secondary addresses (e.g., APT 101, APT 102, etc.) may continue to share a common receptacle if single-point delivery is authorized for the primary address. Secondary addresses should still be included in all correspondence.

2.9Locked Box

A mailbox with a lock must have a slot that is large enough to accommodate the customer’s normal daily mail volume. The USPS neither opens a locked box nor accepts a key for this purpose.

2.10Delivery of Unstamped Newspapers

Generally, curbside mailboxes are to be used for mail only. However, publishers of newspapers regularly mailed as Periodicals may, on Sundays and national holidays only, place copies of the Sunday or holiday issues in the rural route and highway contract route boxes of subscribers if those copies are removed from the boxes before the next scheduled day of mail delivery.

2.11Newspaper Receptacle

A receptacle for newspaper delivery by private carriers may be attached to the post of a curbside mailbox used by the USPS if the receptacle:

a. Does not touch the mailbox or use any part of the mailbox for support.

b. Does not interfere with the delivery of mail, obstruct the view of the mailbox flag, or present a hazard to carrier or vehicle.

c. Does not extend beyond the front of the mailbox when the box door is closed.

d. Does not display advertising, except the publication title.

631 Modes of Delivery

631.1 General

[Revise the first sentence of 631.1 to read as follows:]

The Postal Service-approved modes of delivery available for all existing delivery points, newly established and extensions of delivery points, are described in 631.24.***

* * * * *

[Add new 631.2 through 631.244 to read as follows:]

631.2 Door Delivery

Door delivery may be provided to boxes located at or near the door of a business or residential delivery point, or through a door slot, with prior approval from the local Postmaster, only if the box or mail slot can be efficiently, safely, and conveniently served by the carrier.

Door delivery will generally not be available for new delivery points.

631.21 Sidewalk Delivery

Sidewalk delivery may be provided to boxes located near the public sidewalk. Options and requirements for sidewalk delivery, as directed by the Postal Service, are as follows:

a. If the sidewalk abuts the curb or if other unusual conditions exist (e.g., excessive street parking) that make it difficult or impractical to install or serve boxes at the curbline, customers with these situations may be permitted to install all their boxes at the edge of the public sidewalk nearest the residence, where they can all be served by a carrier from the sidewalk.

b. If the average lot frontage is 50 feet or less, the boxes must be located so that the carrier can serve them from the sidewalk. The boxes are not required to be grouped together.

c. If the average lot frontage is over 50 feet and does not exceed 75 feet, the boxes must be installed in groups of at least two.

d. If the average lot frontage exceeds 75 feet, CBUs must be installed.

631.22 Curbside Delivery

Delivery may only be provided to boxes at the curb with prior approval from the Postal Service, and so long as they can be efficiently, safely, and conveniently served by the carrier from the carrier’s vehicle, and so that customers have reasonable and safe access. Mail receptacles may be grouped two to a property line, where possible.

631.23 Centralized Delivery

Centralized delivery service may be provided to call windows, horizontal locked mail receptacles, cluster box units (CBUs), wall-mounted receptacles, or mechanical conveyors (mechanical conveyors are only for high-rise and multiple tenant buildings, and only if certain conditions are met; consult your Postmaster for details).

a. Delivery requirements: CBUs and USPS STD 4C equipment may be approved for use at one or more centralized delivery points in a residential housing community or business location. The local postal manager must approve the mailbox sites and type of equipment. Boxes must be safely located so that customers are not required to travel an unreasonable distance to obtain their mail and to provide sufficient access to mailbox locations. Normally, it is appropriate for the receptacle to be within one block of the residence.

b. Centralized delivery addresses: Centralized delivery mail receptacles (including USPS STD 4C equipment and CBUs, delivery centers, and postal centers) must be identified by the same addresses as the dwellings for which they serve as mail receptacles. The respective, conforming addresses should be displayed inside the boxes and visible only to the carrier and customer when accessing that receptacle. USPS does not assign addresses; however, the sequential ordering of any centralized delivery equipment is subject to USPS approval for operational efficiency and to accommodate special circumstances or requests for hardship delivery. For security or privacy, mailer associations or customer groups may use another alphanumeric identification system on the outside of receptacles that is not part of, or used in, the mailing address.

631.24 Newly Established or Extended Delivery Points

631.241 General

Newly established or extended business or residential customers must request and receive approval of the delivery location and mode of delivery from the local Postmaster or District designees. These deliveries will not receive mail delivery service until the mail receptacles are installed and the units and locations are approved by local postal management. Options and requirements for modes of delivery are directed by the Postal Service.

631.242 Newly Established or Extended Door Delivery Points

Door delivery will generally not be available for new delivery points. Approval for newly established or extended business or residential door delivery points must come from the Area Vice President or designee. The Area Vice President must report the number of granted requests for newly established or extended business or residential door delivery points to the Chief Operating Officer or designee quarterly.

631.243 Newly Established or Extended Sidewalk or Curbside Delivery Points

Sidewalk or curbside delivery is permitted for new or extended business or residential delivery points. The mail receptacle and location of the delivery points are approved by local postal officials in advance of the occupancy of the residence, business, or other site associated with the delivery points.

631.244 Newly Established or Extended Centralized Delivery Points

Centralized delivery is permitted for new or extended business or residential delivery points. The mail receptacle and location of the delivery point(s) are approved by local postal officials in advance of the occupancy of the residence, business, or other site associated with the delivery point.

631.7 Conversion of Mode of Delivery

[Revise the second and third paragraphs of 631.7 to read as follows:]

***Postmasters may establish a mixed delivery area where in-growth or extensions of service within a block compel a change in modes of delivery for newly constructed or renovated delivery points. This policy applies to both residential and business delivery locations. When a residence is sold, the mode of delivery cannot be changed arbitrarily prior to the new resident moving in. The existing mode of delivery must be retained absent an agreement otherwise. If an owners’ association or property management company represents the property or the community, it may request a change in the mode of delivery on behalf of the community or property. In rental areas, such as apartment complexes and mobile home parks, the owner or manager may request a conversion on behalf of the apartment complex, mobile home park, or other rental property. Approval is at the sole discretion of the Postal Service. Delivery will begin only after the approval of a mail receptacle and its location by the local Postmaster.

Where there is no homeowners’ association or other property management company with authority to request a conversion on behalf of the owners, residents, or the community, customer signatures must be obtained prior to any conversion. In single-family housing areas (including manufactured housing and mobile homes) where the residences and lots are owned, each owner must agree to the conversion in writing. Owners who do not agree must be allowed to retain their current mode of delivery.

631.8 Correction of Improper Mode of Delivery

In the event an improper mode of delivery is established or extended by a postal carrier or manager, the service will be withdrawn with a thirty (30) day advance notice to the affected customer(s), provided that the error is detected and the customer is notified within one (1) year. If the error is not detected and the customer is not notified within one (1) year of the date delivery is established or extended, the improper service remains in place unless the customer consents to the delivery mode change or a delivery point with improper modes of delivery in a vacant delivery is first identified during the vacant period per section 623.5. When the new customer(s) in these vacant deliveries are identified by Postal Service management and informed (within the first 30 days of occupancy) that the current mode of delivery was established incorrectly and will need to be corrected.

[Add new 631.82 to read as follows:]

631.82 Refusal by Customer

If a customer refuses to accommodate the Postal Service’s delivery mode determination by refusing to provide an approved mail receptacle or permit the Postal Service to install its own, General Delivery service may be provided at the nearest postal facility where the carrier delivery emanates or where may be otherwise available to the customer.

[Revise the text of 632.13 to read as follows:]

Usps Door Slot Regulations

[Add new 632.21 and move the text from 632.2 to 632.21 to read as follows:]

632.21 General

Carriers are prohibited from accepting keys for locks on private mail receptacles, buildings, or offices, except where an electromechanical door lock system or a key keeper box located within convenient reach of the door is used. Both devices must incorporate an Arrow lock to access the key or device needed to gain entry to the building. If customers place locks on their receptacles, the receptacles must have slots large enough to accommodate their normal daily mail volume so that delivery may be made by the carrier without using a key.

[Add new 632.22 to read as follows:]

632.22 Locks and Keys

The Postal Service is responsible for providing every customer a compartment lock and three keys to his or her postal-owned Cluster Box Unit (CBU). No key deposits are required; advise customers that they may duplicate their keys at no expense to the Postal Service. Postal managers must take the following actions in issuing and controlling locks and keys for postal-owned CBUs:

a. Give all compartment keys to customers with a notice stating that the Postal Service keeps no duplicate keys and if they lose all the keys, the Postal Service will have to install a new lock at the customer’s expense.

b. If customers lose their keys, arrange for the repairs and charge the customer accordingly.

c. Request that customers return all compartment keys to the Post Office when they move from their residence. When a customer moves, the Post Office should change the lock before reissuing the compartment. The new customer is not charged for the first lock and keys even though the Postal Service replaced it.

d. When new centralized delivery equipment is installed, the keys may either be taped to the inside of the receptacle until the compartment is issued, or stored at the Post Office. A suggested method of storage is to use P-570 envelopes labeled with address, compartment number CBU location, and CBU identifying number.

Note: The builder or property owner is responsible for providing lock and key service for privately owned CBUs.
