An airmail etiquette, often shortened to just etiquette, is a label used to indicate that a letter is to be sent by airmail.
The term "airmail etiquette" derived from the French word étiquette ("label, sticker"), from which is also derived the English word etiquette ("rules of behavior").
Because airmail etiquettes are just instructions to postal clerks, and have no monetary value, their printing and distribution need not be as carefully controlled as for postage stamps, and most are privately produced. The usual design is a plain blue oblong, with the phrases "AIR MAIL" and/or "PAR AVION" in white letters. Various airlines and hotels have also produced etiquettes.
The airmail etiquette may be omitted if airmail stamps are used on the letter, and in some cases even this is not necessary if a country sends out all its foreign mail by air. In some regions, such as the United Kingdom, one may simply write "PAR AVION -- BY AIR MAIL" on the envelope, [1] even though etiquettes are available free of charge from post offices.
The United States officially requires international First Class and Priority Mail letters to be marked with "AIRMAIL/PAR AVION". [2] [3] This requirement is often ignored in modern practice since the United States Postal Service discontinued international surface mail in 2007; [4] all international mail from the US is now sent via airmail. Pre-printed airmail etiquettes are no longer produced by the USPS. If USPS customers purchase international stamps from self-service kiosks, from post offices, or online, the letters must then have "AIRMAIL/PAR AVION" written on the address side of the letter. This applies to both First Class Mail International and Priority Mail International services. [5] [6]
An international reply coupon (IRC) is a coupon that can be exchanged for one or more postage stamps representing the minimum postage for an unregistered priority airmail letter sent to another Universal Postal Union (UPU) member country. IRCs are accepted by all UPU member countries.
The United States Postal Service (USPS), also known as the Post Office, U.S. Mail, or simply the Postal Service, is an independent agency of the executive branch of the United States federal government responsible for providing postal service in the United States, its insular areas and associated states. It is one of a few government agencies explicitly authorized by the Constitution of the United States. As of 2023, the USPS has 525,469 career employees and 114,623 non-career employees.
The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing.
Canada Post Corporation, trading as Canada Post, is a Canadian Crown corporation that functions as the primary postal operator in Canada.
Postal service in the United States began with the delivery of stampless letters whose cost was borne by the receiving person, later encompassed pre-paid letters carried by private mail carriers and provisional post offices, and culminated in a system of universal prepayment that required all letters to bear nationally issued adhesive postage stamps.
Postal history is the study of postal systems and how they operate and, or, the study of the use of postage stamps and covers and associated postal artifacts illustrating historical episodes in the development of postal systems. The term is attributed to Robson Lowe, a professional philatelist, stamp dealer and stamp auctioneer, who made the first organised study of the subject in the 1930s and described philatelists as "students of science", but postal historians as "students of humanity". More precisely, philatelists describe postal history as the study of rates, routes, markings, and means.
Airmail is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked Par avion, literally: "by airplane".
An airmail stamp is a postage stamp intended to pay either an airmail fee that is charged in addition to the surface rate, or the full airmail rate, for an item of mail to be transported by air.
Aerophilately is the branch of philately that specializes in the study of airmail. Philatelists have observed the development of mail transport by air from its beginning, and all aspects of airmail service have been extensively studied and documented by specialists.
Registered mail is a postal service in many countries which allows the sender proof of mailing via a receipt and, upon request, electronic verification that an article was delivered or that a delivery attempt was made. Depending on the country, additional services may also be available, such as:
Franking comprises all devices, markings, or combinations thereof ("franks") applied to mails of any class which qualifies them to be postally serviced. Types of franks include uncanceled and precanceled postage stamps, impressions applied via postage meter, official use "Penalty" franks, Business Reply Mail (BRM), and other permit Imprints (Indicia), manuscript and facsimile "franking privilege" signatures, "soldier's mail" markings, and any other forms authorized by the 192 postal administrations that are members of the Universal Postal Union.
The system for mail delivery in the United States has developed with the nation. Rates were based on the distance between sender and receiver in the nation's early years. In the middle of the 19th century, rates stabilized at one price regardless of distance. Rates were relatively unchanged until 1968 when the price was increased every few years by a small amount. Comparing the increases with a price index, the cost of a first-class stamp has been steady. The seal of the Post Office Department showed a man on a running horse, even as railroads and, later, motorized trucks and airplanes moved mail. In 1971, the Post Office became the United States Postal Service, with rates set by the Postal Regulatory Commission, with some oversight by Congress. Air mail became standard in 1975. In the 21st century, prices were segmented to match the sorting machinery used; non-standard letters required slightly higher postage.
A postage meter or franking machine is a mechanical device used to create and apply physical evidence of postage to mailed items. Postage meters are regulated by a country's postal authority. A postage meter imprints an amount of postage, functioning as a postage stamp, a cancellation and a dated postmark all in one. The meter stamp serves as proof of payment and eliminates the need for adhesive stamps.
Parcel post is a postal service for mail that is too heavy for normal letter post. It is usually slower than letter post. The development of the parcel post is closely connected with the development of the railway network which enabled parcels to be carried in bulk, to a regular schedule, and at economical prices. Today, many parcels also travel by road and international shipments may travel by sea or airmail.
Non-denominated postage is a postage stamp intended to meet a certain postage rate, but printed without the denomination, the price for that rate. They may retain full validity for the intended rate, regardless of later rate changes, or they may retain validity only for the original purchase price. In many English-speaking countries, it is called non-value indicator or non-value indicated (NVI) postage. They are used in many countries and reduce the cost of printing large issues of low-value make up stamps.
U.S. Special Delivery was a postal service paid for with additional postage for urgent letters and postal packets which are delivered in less time than by standard or first class mail service. Its meaning is different and separate from express mail delivery service. Essentially it meant that a postal packet was delivered from a post office to the addressee immediately once it arrived at the post office responsible for delivering it, rather than waiting for the next regular delivery to the addressee.
Printed matter is a term, mostly used by mailing systems, normally used to describe mechanically printed materials for which reduced fees are paid which are lower than first-class mail. Each postal administration has its own rules for what may be posted as printed matter. In the Great Britain a special "Book Post" was introduced in 1848 that by 1852 had been extended to the wider range of material.
United States airmail was a service class of the United States Post Office Department (USPOD) and its successor United States Postal Service (USPS) delivering air mail by aircraft flown within the United States and its possessions and territories. Letters and parcels intended for air mail service were marked as "Via Air Mail", appropriately franked, and assigned to any then existing class or sub-class of the Air Mail service.
Surface mail, also known as sea mail, is mail that is transported by land and sea, rather than by air, as in airmail. Surface mail is significantly less expensive but slower than airmail, and thus is preferred for large or heavy, non-urgent items and is primarily used for sending packages, not letters.
