DMM TOC > 600 Basic Standards for All Mailing Services608 Postal Information and Resources1.0 About the Domestic Mail Manual1.1 Content of the DMMMailing Standards of the United States Postal Service, Domestic Mail Manual (DMM) contains the basic standards of the United States Postal Service (USPS) governing its domestic mail services; descriptions of the mail classes and extra services and conditions governing their use; and standards for price eligibility and mail preparation. Domestic mail is classified by size, weight, content, service, and other factors. 1.2 Copies of the DMMThe DMM is distributed to selected Post Offices and is available online on Postal Explorer (pe.usps.com). Copies of the DMM may be inspected during normal business hours at USPS Headquarters; area and district offices. A copy is also filed at the Office of the Federal Register, National Archives and Records Administration. The public may buy copies by subscription from the Superintendent of Documents, U.S. Government Printing Office (see 8.1 for address). 1.3 Revisions to the DMMUSPS may change the standards in the DMM. Substantive revisions are published in the Postal Bulletin and, when appropriate, the Federal Register. 1.4 Terms in the DMMTerms in the DMM referring to the singular also apply to the plural, unless the context indicates otherwise. The term postmaster also applies to an officer-in-charge if the postmaster position is vacant and, in district host cities, to the district manager. 2.0 Domestic Mail2.1 Definition of "Domestic"Domestic mail is mail transmitted within, among, and between the United States of America, its territories and possessions, Army Post Offices (APOs), fleet Post Offices (FPOs), and the United Nations, NY. For this standard, the term "territories and possessions" comprises the following:
2.2 Mail Treated as DomesticMail originating in the United States of America, its territories and possessions, APOs, FPOs, and the United Nations, NY, for delivery in the Freely Associated States, and mail originating in the Freely Associated States for delivery within, among, and between the Freely Associated States and the United States of America, its territories and possessions, APOs, FPOs, and the United Nations, NY, is treated as if it were domestic mail. The term "Freely Associated States" comprises the following:
2.3 International MailInternational mail is mail addressed to or received from foreign countries, except under 2.2. Provisions for international mail are published in the International Mail Manual. 2.4 Customs Forms Required2.4.1 Priority Mail Weighing 16 Ounces or More[4-5-10] [11-2-09] Regardless of contents, all Priority Mail weighing 16 ounces or more sent from the United States to the ZIP Code destinations listed in the table below, and all Priority Mail sent from these ZIP Code destinations to the United States, must bear a properly completed PS Form 2976-A, Customs Declaration and Dispatch Note CP 72. If PS Form 2976-A will not fit on the address side of the mailpiece, a PS Form 2976, Customs Declaration CN 22, must be used.
2.4.2 Enter and Deposit—Items Requiring a Completed Customs Declaration[4-5-10] Except as provided in 2.4.3, a mailer may not deposit an item that requires a completed customs declaration into a collection box, Postal Service lobby drop, Automated Postal Center (APC) drop, customer mailbox, or at a Postal Service dock or other unattended location. In addition, these mailpieces are precluded from Pickup on Demand service and Carrier Pickup service under 507.6.0. Customers must present such items to an employee at a Post Office retail service counter. The Postal Service will return improperly presented items to the sender for proper entry and acceptance. 2.4.3 Items Bearing a Completed Customs Declaration with an Electronic Round Date[4-5-10] Items under 2.4.1 that have the mailing label, customs declaration (including an electronic round date), and postage prepared and paid online through an authorized PC Postage vendor Web site may be deposited only as follows: a. At a Postal Service retail counter. b. Through Pickup on Demand service. c. Through Carrier Pickup service. d. Into a Postal Service lobby drop. e. Into an Automated Postal Center (APC) drop. f. In a U.S. Postal Service collection box. g. In the mailing customer's residential or business mailbox. 2.4.4 Freely Associated States—Items Requiring an Export License[11-2-09] Items sent to the Freely Associated States listed in 2.2 that require an export license under 2.5.8, regardless of weight or class of mail, always require a PS Form 2976-A. See IMM 530 for additional information on export licenses. 2.5 Foreign Trade Regulations—U.S. Department of Commerce, U.S. Bureau of the Census[11-2-09] This section describes the various U.S. Department of Commerce, U.S. Bureau of the Census requirements when shipping goods to, from, and between U.S. territories, possessions, and Freely Associated States. Shipments to APO/FPO/DPO addresses are not subject to these requirements. Customers may be subject to civil and criminal penalties if they fail to electronically file their export information when required, or if they fail to comply with the Foreign Trade Regulations in any other way. Refer to IMM 520 for additional standards about the Census Bureau's requirements. 2.5.1 Mandatory Electronic Filing—U.S. Territories, Possessions, and Freely Associated States[11-2-09] Under the authority of 13 U.S.C. Chapter 9, as amended by the Foreign Relations Authorization Act of 2002, P.L. 107-228, U.S. Census Bureau regulations require electronic filing of export information through the U.S. Census Bureau's Automated Export System or AESDirect website for certain or AESDirect website for certain shipments of goods. Electronic filing of export information is required when any of the following applies, subject to certain exemptions and exclusions (see 2.5.4): a. The item requires an export license under U.S. law when sent to the Freely Associated States. See 2.5.5 and 2.5.6. b. One or more classes of goods (per Schedule B Export Codes at www.census.gov/foreign-trade/schedules/b) within the item is valued at more than $2,500 and the item is mailed as follows: 1. From Puerto Rico to the United States or U.S. Virgin Islands. 2. From the United States to Puerto Rico or the U.S. Virgin Islands. 3. From the United States, Puerto Rico, or the U.S. Virgin Islands to the Freely Associated States. 2.5.2 Value Criterion[11-2-09] Following are three examples to illustrate the value criterion defined in 2.5.1: a. A package contains one mechanically operated watch (Schedule B item # 9101.11.0000) valued at $2600. The total value of goods to be mailed is $2600, and the value of all items within the same Schedule B number is over $2500. Consequently, electronic filing and a PFC would be required (unless an exemption or exclusion applies). b. A package contains one mechanically operated watch (Schedule B item # 9101.11.0000) valued at $2400, and one electronically operated watch (Schedule B item # 9101.91.0000) valued at $2400. The total value of goods to be mailed is $4800, but no group of items within the same Schedule B number is valued over $2500. Consequently, electronic filing and a PFC would not be required, because the mechanical watch and electronic watch are in different Schedule B groups, c. A package contains two mechanically operated watches (Schedule B item # 9101.11.0000) one valued at $1400 and one valued at $1500. The total value of goods to be mailed is $2900 and the value of all items within the same Schedule B number is over $2500. Consequently, electronic filing and a PFC would be required, unless an exemption or exclusion applies. 2.5.3 How to File Electronic Export Information and Obtain a Proof of Filing Citation[11-2-09] For additional information on electronic filing, call the U.S. Census Bureau's toll-free information hotline at 800-549-0595, option #3. To file electronic export information through AESDirect and obtain a PFC, customers should use the following steps: b. Register for an AESDirect account or log into your existing account. c. Follow the instructions for the Automated Export System Certification Quiz. d. The "Port of Export" code for shipping through the Postal Service is "8000". e. The "Mode of Transport" is "Mail". f. Leave the carrier as 'SCAC/IATA' and the conveyance name fields blank. g. After successfully filing electronic export information, AESDirect will provide an alphanumeric Internal Transaction Number (ITN) as confirmation. The PFC consists of the letters "AES" followed by the ITN: for example, "AES X20080930987654". 2.5.4 AES Downtime Citation[11-2-09] If electronic information filing is required but U.S. Census Bureau's Automated Export System or AESDirect website is unavailable, the goods may be shipped but the customer is responsible for providing the appropriate AES Downtime Citation instead of a PFC. This citation includes the word "AESDOWN," the customer's AES filer identification number, and the date: for example, "AESDOWN 123456789 09/30/2009." If the Automated Export System system is down, call 800-549-0595, option 1. 2.5.5 Exclusion and Exemption Legends[11-2-09] In many circumstances, electronic export information filing and a Proof of Filing Citation (PFC) may not be required. In these circumstances, and only when a customs declaration form is required under 2.4, customers are responsible for presenting an applicable Exemption or Exclusion Legend on the customs declaration form upon mailing. Customers may forgo this requirement if no customs declaration form is required. When a customs declaration form is used, customers should enter the applicable Exemption or Exclusion Legend on the customs declaration form. Customers must only enter one Exemption or Exclusion Legend per addressed mailpiece. When multiple Exemption or Exclusion Legends may apply, the mailer may select any one that applies. For more information on these and other exemptions and exclusions, customers should consult Appendix C of the Foreign Trade Regulations, 15 C.F.R. Part 30. The following is a list of the most commonly applicable Exemption or Exclusion Legends for items mailed to, from, or between destinations under 2.0. a. Regardless of value, for all goods shipped to, from, or between the following U.S. Territories, use "NOEEI 30.2(d)(2)": b. For items destined to the Freely Associated States listed in 2.2, customers may apply "NOEEI 30.37(a)" if the value of each class of goods is $2,500 or less, provided an export license is not required (see 2.5.7 and 2.5.8). 2.5.6 Placement of PFC, AES Downtime Citation Placement, or Exemption and Exclusion Legend[11-2-09] If no customs declaration form is required (e.g., items sent between the United States, Puerto Rico, and the U.S. Virgin Islands), no other action for recording the PFC or AES Downtime Citation on the package is required. However, when a shipment requires a PFC, or AES Downtime Citation, or Exemption and Exclusion Legend, and a PS Form 2976-A is used under 2.4; it is the customer's responsibility to legibly write the PFC, AES Downtime Citation, or Exemption or Exclusion Legend as follows: a. On PS Form 2976-A, Customs Declaration and Dispatch Note - CP72 (large white form) customers should write one PFC, AES Downtime Citation, or Exemption or Exclusion Legend in Block 11. b. On older versions of PS Form 2976-A printed prior to January 2009 customers should write one PFC, AES Downtime Citation, or Exemption or Exclusion Legend at the top of the form or in any clear space. Avoid writing over the barcode on the form. 2.5.7 Additional Standards for the Freely Associated States[11-2-09] The Freely Associated States listed in 2.2 are foreign destinations for the purposes of the Foreign Trade Regulations and other laws and regulations governing imports and exports. As such, certain goods shipped to these destinations from the United States, Puerto Rico, the U.S. Virgin Islands, or other U.S. territories may require an export license. To determine if an export license is required, go to http://www.export.gov/regulation/index.asp or call: 1-800-USA-TRAD(E) (1-800-872-8723). 2.5.8 When an Export License Is Required[11-2-09] When an export license is required under 2.5.7, a PS Form 2976-A is always required. The electronically generated License Number must appear in Block 13, and a PFC or AES Downtime Citation must appear in Block 11 of the customs declaration form. See IMM 520 and 530 for complete requirements. In addition, it is the mailer's responsibility to comply with the U.S. Census Bureau's requirements for filing electronic export information, as described in 2.5.1 and 2.5.2. A PFC or AES Downtime Citation should appear on the customs declaration form as described in 2.5.6. 3.0 Post Offices and Holidays3.1 Management of Post Offices3.1.1 Establishment of Post OfficesThe USPS establishes and maintains Post Offices, stations, and branches for customer convenience. 3.1.2 Closing or Consolidation of Post OfficesUnder 39 U.S. Code (USC) 404(b), any decision to close or consolidate a Post Office must be based on certain criteria. These include the effect on the community served; the effect on employees of the Post Office; compliance with government policy established by law that the USPS must provide a maximum degree of effective and regular postal services to rural areas, communities, and small towns where Post Offices are not self-sustaining; the economic savings to the USPS; and other factors that the USPS determines necessary. In addition, certain mandatory procedures apply. 3.1.3 Procedures for Post OfficesThe Postal Operations Manual contains USPS rules for discontinuing, consolidating, or suspending service at an existing Post Office or other postal facility; changing a Post Office or other postal facility name; setting public business hours of postal facilities; and using bulletin boards and handling lost articles found in public areas of postal facilities. 3.1.4 Military Post OfficesMilitary Post Offices (MPOs) are branches of a U.S. civil Post Office, operated by the Army, Navy, Air Force, or Marine Corps to serve military personnel overseas or aboard ships. The term includes Army Post Offices (APOs) for the U.S. Army and the U.S. Air Force and fleet Post Offices (FPOs) for the U.S. Navy and the U.S. Marine Corps. MPOs provide postal service for military personnel where the U.S. civil postal service does not operate and a military situation requires the service. MPOs are established or discontinued by the USPS only on request of the military department that operates them. Notice of these actions is published in the Postal Bulletin. Military Post Offices do not verify and accept bulk or discounted-price mail; such mailings must be deposited at (nonmilitary) U.S. Post Offices. 3.2 Holiday ServiceExhibit 3.2a and Exhibit 3.2b shows the national holidays observed by the USPS and the service levels provided on those holidays for retail window, Post Office box, firm call, delivery, and collection services.

Damaged envelopes canceled with a special cancellation are not replaced. 5.0 Private Express Statutes5.1 Private Express Statutes5.1.1 Legal Foundation[11-29-09] By the laws known as the Private Express Statutes, Congress has generally conferred on the USPS the exclusive right to carry letters for others over post routes. USPS regulations under the Private Express Statutes are in the Code of Federal Regulations, 39 CFR 310 and 320, as amended by final rules published in the Federal Register. These regulations take precedence over all prior rulings and USPS publications. Copies of the regulations are available from the manager of Mailing Standards, USPS Headquarters (see 8.1 for address). 5.1.2 Definition of a Letter for Private ExpressFor the Private Express Statutes, a letter is a message directed to a specific person or address and recorded in or on a tangible object. A message consists of any information or intelligence that can be recorded on tangible objects including, but not limited to, paper in sheet or card form, recording disks, and magnetic tapes. Certain matter is excluded from the definition of letter, e.g.: telegrams; checks and certain other instruments shipped to, from, or between financial institutions; newspapers; and periodicals. The regulations detail exclusions. 5.1.3 Postage for Private ExpressIf the proper postage is paid, letters may be privately carried without violating the Private Express Statutes. The regulations detail compliance. Under certain circumstances, letters may be privately carried without paying postage. The principal exceptions cover letters sent with, and related in all substantial respects to, some part of the cargo or to the ordering, shipping, or delivering of the cargo; letters carried by the senders or the recipients, or by their regular salaried employees; and letters carried to or from a postal facility where they are to be or have been carried in the mail. The regulations detail exceptions. 5.1.4 Suspensions of Private Express Statutes[11-29-09] Limited suspensions of the Private Express Statutes specify the conditions under which: (a) private couriers may carry data-processing materials, international ocean carrier documents, extremely urgent letters, and advertisements incidental to the shipment of accompanying merchandise or periodicals; and (b) universities and colleges may carry the letters of their bona fide student and faculty organizations. Carriers wanting to use the suspension for data-processing materials must file a notice of their intention on a form available from the manager of Mailing Standards. 5.1.5 Violations of Private Express Statutes[11-29-09] Mailing Standards, USPS Headquarters, is responsible for reviewing initial reports of possible violations of the Private Express Statutes. When warranted by the facts, possible violations are forwarded to the USPS General Counsel for further action. 5.1.6 Legal Advice for Private Express[11-29-09] The public and USPS employees can obtain authoritative advice on the Private Express Statutes, including written advisory opinions, by contacting the Senior Counsel, Ethics and Information, USPS Headquarters (see 8.1 for address and telephone number). 6.0 Complaints and Postal Law Violations6.1 Consumer Complaints and InquiriesAny postal customer may complain or inquire about postal products, services, or employees at any Post Office or directly to the USPS Consumer Advocate (see 8.1 for address). A complaint or inquiry may be made in person, by telephone, by e-mail, or by letter. A complaint or inquiry about the handling of a specific piece of mail should include the related envelope or wrapper and copies of all postal forms filed. A customer who is dissatisfied with the local handling of a complaint or inquiry may send a written appeal to the Consumer Advocate. A court of law can require such appeal as a legal prerequisite for hearing a customer's suit against the USPS. 6.2 Postal Law ViolationsInstructions on mail security as it relates to unauthorized opening, inspection, tampering, or delay of mail are in Administrative Support Manual 274.
