Domestic Mail FAQs


Q. Can the Forever Stamp be used on mailpieces that require extra postage?

A. Forever Stamp First-Class Stamp.Yes. The postage value of a Forever Stamp is the cur­rent First-Class Mail single-piece 1-ounce letter rate — $0.41. Customers must affix additional postage when mailing letters weighing in ex­cess of 1 ounce and/or letters subject to the nonmachinable sur­charge or mailpieces subject to another rate of post­age (e.g., large envelopes or packages).

Q. American Flag First-Class Stamp.How may cus­tomers who have a number of dif­ferent stamps with no denomi­nation determine the value of those stamps?

A. DMM Quick Ser­vice Guide 604a details all nonde­nominated post­age issued since 1975. Go to and click Quick Service Guides.

Q. Where can customers find additional information regarding domestic and international rates and fees?

A. Additional information on domestic and international rates and fees can be found at International delivery options can be found at

Q. Pickup on Demand service increased to $14.25. What about Carrier Pickup service — did that change?

A. Carrier Pickup service remains available at no charge. Customers may schedule Carrier Pickup service or Pickup on Demand service online at Pickup on Demand service may be also be scheduled by calling 800-222-1811. Note: Mailpieces that weigh over 13 ounces and that bear only postage stamps as postage must be pre­sented for mailing to an employee at a Post Office retail counter.

First-Class Mail

Q. Are letter-size greeting cards weighing more than 1 ounce subject to the nonmachinable surcharge?

A. Yes. The $0.17 nonmachinable surcharge criteria applies to all First-Class Mail letters (up to the 3.5–ounce maximum weight). However, greeting cards that are classified and priced as flats are not subject to the nonmachinable surcharge.

Q. How are “rigid” letter-size greeting cards priced?

A. If a mailpiece does not exceed 11-1/2 inches x 6-1/8 inches x 1/4 inch thick and 3.5 ounces, but is rigid, it is classified and priced as a nonmachinable letter (i.e., applicable First-Class Mail postage and $0.17 nonmachinable surcharge apply).

Q. Are large envelopes (flats) subject to a nonmachin­able surcharge?

A. No. Since large envelopes have their own price struc­ture (flats prices), the nonmachinable surcharge does not apply.

Q. If a First-Class Mail piece is larger than letter-size, does it have to be over 1/4 inch thick to be priced as a “large envelope”?

A. No. The 1/4 inch thickness is just one of the three maximum measurements for letter-size pieces. If the mailpiece exceeds any one of the measurements, it is classified and priced as a large envelope (flat) as long as it does not exceed any of the flat-size maxi­mum dimensions and has all the other characteristics of a large envelope (flat).

Q. If a flat-size First-Class Mail piece is rigid, is that piece charged the parcel rate?

A. Yes. If the physical dimensions are within flat-size standards, and the mailpiece is rigid, it is classified and priced as a package (parcel). Notice 3-S, First-Class Mail Shape-Based Pricing Template, is a useful tool to help determine First-Class Mail prices.

Q. Did the Postal Service make any changes to any of its processing categories used to determine shape-based rates?

A. No. The minimum and maximum sizes for First-Class Mail card rate, letters, and flats have not changed — see page 27 in this issue of the Postal Bulletin.

First-Class Mail - Single-Piece RatesFirst-Class Mail - Single-Piece Rates

Q. How large can an envelope be and still be eligible for First-Class Mail letter rates?

A. The maximum size is 11-1/2 inches x 6-1/8 inches x 1/4 inch thick. Determining the processing category of a mailpiece (letter, flat, or parcel) is dependent solely on the physical dimensions of the piece with­out regard to address placement. If an envelope exceeds any of the physical dimensions, or 3.5 ounc­es in weight, it is classified and priced as a large envelope (flat).

Q. Are items sent at First-Class Mail flats rates (large envelopes) required to be flexible and “uniformly thick”?

A. Yes. Large envelopes as well as padded mailing bags must be somewhat flexible (not rigid) and uniformly thick. Items mailed in large envelopes cannot have more than a 1/4 inch variance in thickness. Also, mailpieces must be rectangular with a maximum thickness (at the thickest point) of 3/4 inch. A mail­piece that exceeds any one of the maximum physical dimensions (15 inches x 12 inches x 3/4 inch thick) is classified and priced as a package (parcel).

Q. Would items such as photos mailed in a large enve­lope with cardboard or “stiffeners” inserted to prevent bending be subject to package rates?

A. Yes. For additional information, see DMM 101.2.3.

Priority Mail

Q. With dimensional-weight pricing for Priority Mail packages, is there still the balloon rate?

A. Yes, but only for packages measuring larger than 84 inches combined length and girth traveling locally up to Zone 4 with the minimum rate being the 20–pound rate.

Q. Are packages measured the same way for dimensional-weight pricing as for balloon-rate pricing?

A. No. Dimensional-weight is based on cubic inches by measuring (in inches) and multiplying the length by the width by the height. If the result is greater than 1,728, divide it by 194 (the “dim factor”). The result is the dimensional-weight. The Smart Mat may be used to determine if a parcel is eligible for dimensional-weight pricing. Balloon-rate is determined by mea­suring the length and girth combined, and if the result is greater than 84 inches, balloon-rate pricing may apply.

Q. Are complimentary Priority Mail boxes, including the flat-rate boxes, subject to dimensional-weight pricing or the balloon-rate?

A. No. Complimentary Priority Mail containers available online or at Post Offices are not subject to dimensional-weight or balloon-rate pricing.

Express Mail

Q. Is insurance included in the base price for Express Mail?

A. Yes, merchandise insurance is provided against loss, damage, or rifling up to a maximum liability of $100. Additional insurance up to $5,000 may still be pur­chased for a fee, at the customer’s option. Note: The maximum amount of insurance available for purchase online is $500. The maximum amount of insurance available for purchase at the retail counter is $5,000. Online insurance cannot be combined with insurance purchased at the retail counter. Customers wishing to ensure items for more than $500 should purchase the whole insurance amount at the retail counter.

Q. If a customer purchases additional insurance, can the “waiver of signature” option be selected?

A. No. If a waiver of signature is requested, any addi­tional insurance coverage is void. This information is printed on the Express Mail label.

Q. Does dimensional-weight pricing apply to Express Mail shipments?

A. No. Dimensional-weight pricing only applies to Priority Mail.

Package Services

Q. Can postage for Bound Printed Matter (BPM)–eligible items be purchased at the retail counter?

A. Single-piece nonpresorted BPM is no longer offered as an option for mailing flats and parcels at the retail counter. However, we accept nonpresorted BPM pieces for mailing at the retail counter (as well as col­lection boxes and letter carriers, as appropriate) if the customer has pre-applied postage using adhesive stamps, meter strips, or PC Postage. We sell postage (stamps or PVI labels) for BPM items only when cus­tomers specifically request BPM.

Q. Were there any changes to Media Mail eligibility?

A. There were no significant changes to Media Mail. As a reminder, eligible contents are limited to books, sound recordings, recorded videotapes, and com­puter-readable media (not blank). Media Mail cannot contain advertising, except eligible books may con­tain incidental announcements of books. Rates are still unzoned and based on weight.

Extra Services

Q. Where can electronic Return Receipt service be purchased?

A. Return Receipt (electronic) service is available on eligible mailpieces at Post Offices that have integrat­ed retail terminals (IRTs) and point of service (POS) terminals. It is not available at manual offices.

Q. How are mailpieces with partial or full postage han­dled when a customer has requested an electronic Return Receipt?

A. There is a process that must be followed in IRT/POS Post Offices. The standard operating procedures for this process can be found on the Retail Operations page at; click on SOPs in the left navigation bar of the Web page.

Q. Can gift cards be insured?

A. Gift cards may be insured for their full value only when sent by Registered Mail service. Otherwise, gift cards sent by Express Mail service (which includes Express Mail insurance) or another class of mail with merchandise insurance are protected only up to the maximum indemnity for cash and negotiable items — $15. Customers should check the terms of their gift cards as many are replaceable by the issuer if they are lost or stolen.

Q. What if a customer wishes to purchase domestic (or international) postage online and insure the item for more than $500?

A. Insurance purchased online is limited to $500, whereas insurance purchased at any Post Office facility is available in amounts up to $5,000. Insur­ance purchased online cannot be combined with additional insurance purchased later at a Post Office. Customers may purchase postage online and bring the item to a Post Office to purchase insurance up to $5,000.

Q. How can a customer determine if an insured item has been delivered?

A. For any item insured for more than $200, customers can purchase a return receipt (hardcopy or electron­ic). A return receipt after mailing can be used if no return receipt was purchased at the time of mailing. For Priority Mail pieces, First-Class Mail parcels, and Package Service parcels, regardless of the insured value, customers can purchase Delivery Confirma­tion or Signature Confirmation service at the time of mailing. Delivery information is available by inputting the Delivery Confirmation or Signature Confirmation number (not the insured number) online at; click on Track and Confirm. Customers may also call 800-222-1811. Always encourage customers to save their insurance receipt in case they need to file a claim.

Q. Are there any changes to the criteria for mailpieces eligible for Delivery Confirmation or Signature Confir­mation service?

A. No. Delivery Confirmation and Signature Confirma­tion services are available for all Priority Mail pieces, First-Class Mail packages, and Package Services packages (e.g., Parcel Post). First-Class Mail and Package Services items must be greater than 3/4 inch thick at their thickest point, unless the item is prepared in a strong and rigid fiberboard or similar container or in a container that becomes rigid after the contents are enclosed and the container is secured. The rigid package must be greater than 1/4 inch thick, and be able to maintain its shape, integrity, and rigidity throughout processing and handling. Customers cannot pay First-Class Mail package rates for items that are classified as letters or flats.

Q. Are there any size (shape) standards for items sent with postal insurance?

A. No. All mail shapes — letters, large envelopes, and packages containing insurable merchandise — may be insured and sent as Priority Mail, First-Class Mail, or Package Services items.

Q. What is PAL or Parcel Airlift?

A. PAL (parcel airlift service) provides air transportation for parcels on a space-available basis to or from mil­itary post offices (MPOs) outside the 48 contiguous states. It is available for Package Services mail that does not exceed 30 pounds or 60 inches in length and girth combined. Packages must be marked “PAL” on the address side, preferably below the postage and above the addressee’s name. The appli­cable PAL fee must be paid in addition to the Pack­age Services postage.

International Mail FAQs


Q. Can the Forever Stamp be used on international mail?

A. Yes, however, since international postage rates are always higher, additional postage would have to be affixed. Any nondenominated stamps (except for those that bear unique markings, such as First-Class Presort, Nonprofit Org.) may be affixed to items that are sent to foreign destinations. The postage value of such stamps is linked to its appropriate domestic rate (e.g., the Breast Cancer Research semipostal stamp and the American Flag stamp have a postage value of $0.41).

Q. Why were changes made to the structure of interna­tional mail?

A. The international mail product line was restructured to better meet customer needs. Over time, custom­ers had expressed the desire for clear and concise product options to choose from. They wanted to have the same quick, easy, and convenient shipping options that are available domestically. Also, cus­tomers had stated a preference for using the same Postal Service–provided packaging for both domes­tic and international shipments, free Carrier Pickup service, and better tracking and package visibility — all at the Postal Service’s competitive prices.

Q. What are some of the major changes that were made to international mail?

A. The changes include a simplification and rebranding of all international products. Eight international prod­ucts with overlapping prices and service standards were combined into four: Global Express Guaranteed (GXG), Express Mail International, Priority Mail Inter­national, and First-Class Mail International.

Q. What international products are no longer offered?

A. Economy (surface) products including economy par­cel post; economy letter post; publishers’ periodi­cals, books, and sheet music; and economy M-bags are no longer offered. In place of these services we now offer comparable air product alternatives. In addition, aerogrammes and recorded delivery ser­vice were eliminated. First-Class Mail International letters and cards are alternatives to aerogrammes, and Registered Mail is an alternative for recorded delivery.

Q. What are some of the benefits that the new interna­tional services offer?

A. Customers have the convenience of using domestic shipping supplies, including “flat-rate” options, as well as increased visibility and more specific delivery times to major destinations. Additionally, online ship­pers qualify for postage discounts of up to 10 percent for GXG, Express Mail International, and Priority Mail International when paying postage online at or through authorized PC Postage vendors.

Q. Can Express Mail and Priority Mail “prepaid” Flat-Rate Envelopes be used for international mail?

A. Yes. However, since international rates are always higher than the postage value, additional postage as well as appropriate customs forms would have to be affixed. Express Mail and Priority Mail prepaid enve­lopes are only available for purchase online at

Q. Which of the four new international products offer insurance and tracking?

A. GXG and Express Mail International include insur­ance up to $100 for loss, damage, rifling, or docu­ment reconstruction. Priority Mail International also includes limited insurance coverage.

Q. Must customers declare the specific contents and value on customs forms?

A. Yes. The package contents description is required on shipments going to foreign countries and is subject to the restrictions and prohibitions of that country.

Q. Is the sender required to state the value of an interna­tional shipment sent as a gift on the customs form?

A. Yes. Shipments may be subject to duties and taxes based on contents and their value. Because each country has regulations about what it will allow into the country, everything that enters that country and its value must be identified.

If a customer receives an article from a foreign coun­try in damaged condition, or with some or all contents missing, the customer needs to take the mailing container, wrapping, packaging, and any oth­er contents to any Post Office for inspection. The postmaster will verify damage and give the customer a PS Form 2855, Claim for Indemnity International Registered Mail, Insured, Ordinary Parcel and Express Mail, to complete.
