Surface Air Lifted (SAL) is a postal service used to send international mail items. Thirty-nine postal authorities provide this service. [1] It is a cost-effective international mail. At first SAL mail is processed and transported by surface in the origin country. Then it is transported by air to the destination country and finally processed and delivered as standard-type mail by the destination postal administration. [2] [3] The service is faster than surface mail while the cost is lower than air mail. [2] SAL is more economical for sending heavy items; with light items, it sometimes costs more than air mail. [4]
Prior to World War II a number of European countries adopted the practice of forwarding letters to distant destinations at no extra cost to the sender (such as British mail sent to most parts of the British Empire). The consistently high costs of air mail curtailed this trend after the war. During the mid-1960s in response to the continuing increase of aircraft capacity, the UPU adopted the policy of maximizing air conveyance of mail and in the mid-1970s the concept of “surface air lifted” mail was developed in conjunction with the International Air Transport Association (IATA).
This arrangement allows some mail to receive, for little or no surcharge, speedier transmission than by surface but without the priority of fully surcharged mail. [5]
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 of up to twenty grams sent to another Universal Postal Union (UPU) member country. IRCs are accepted by all UPU member countries.
A postage stamp is a small piece of paper issued by a post office, postal administration, or other authorized vendors to customers who pay postage. Then the stamp is affixed to the face or address-side of any item of mail—an envelope or other postal cover —which they wish to send. The item is then processed by the postal system, where a postmark or cancellation mark—in modern usage indicating date and point of origin of mailing—is applied to the stamp and its left and right sides to prevent its reuse. Next the item is delivered to its addressee.
The United States Postal Service (USPS), also known as the Post Office, U.S. Mail, or Postal Service, is an independent agency of the executive branch of the United States federal government responsible for providing postal service in the U.S., including its insular areas and associated states. It is one of the few government agencies explicitly authorized by the Constitution of the United States. The USPS, as of 2021, has 516,636 career employees and 136,531 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.
Robert Aurand Moon, sometimes called "Mr. ZIP", is considered the father of the ZIP Code or Zone Improvement Plan, a mechanism to route mail in the United States.
Canada Post Corporation, trading as Canada Post, is a Crown corporation that functions as the primary postal operator in Canada. Originally known as Royal Mail Canada, rebranding was done to the "Canada Post" name in the late 1960s, even though it had not yet been separated from the government. On October 16, 1981, the Canada Post Corporation Act came into effect. This abolished the Post Office Department and created the present-day Crown corporation that provides postal service. The act aimed to set a new direction for the postal service by ensuring its financial security and independence.
International Distributions Services plc, trading as Royal Mail, Parcelforce and GLS, is a British multinational postal service and courier company, originally established in 1516 as a government department.

GLS Group, an international logistics company, is a wholly owned subsidiary of Royal Mail Group. The group used the name Consignia for a brief period in the early 2000s and Royal Mail until October 2022.
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.
Cargo consists of goods conveyed by water, air, or land. In economics, freight is cargo that is transported at a freight rate for commercial gain. Cargo was originally a shipload but now covers all types of freight, including transport by rail, van, truck, or intermodal container. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities. The term freight is commonly used to describe the movements of flows of goods being transported by any mode of transportation.
Registered mail is a mail service offered by postal services in many countries which allows the sender proof of mailing via a mailing 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:
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 early years of the nation. In the middle of the 19th century, rates stabilized to 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 price of a first class stamp has been steady. The logo for the Post Office Department showed a man on a running horse, even as the railroads and then 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 in use; non-standard letters required slightly higher postage.
Express mail is an expedited mail delivery service for which the customer pays a premium for faster delivery. Express mail is a service for domestic and international mail, and is in most nations governed by the country's own postal administration. Since 1999, the international express delivery services are governed by the EMS Cooperative.
Military mail, as opposed to civilian mail, refers to the postal services provided by armed forces that allow serving members to send and receive mail. Military mail systems are often subsidized to ensure that military mail does not cost the sender any more than normal domestic mail. In some cases, military personnel in a combat zone may post letters and packages to their home country free of charge. Modern military mail services are provided by most armed forces around the world. In some nations, individual service branches may run their own military mail program.
A flat fee, also referred to as a flat rate or a linear rate refers to a pricing structure that charges a single fixed fee for a service, regardless of usage. Less commonly, the term may refer to a rate that does not vary with usage or time of use.

Mail sorting refers to the methods by which postal systems determine how and where to route mail for delivery. Once accomplished by hand, mail sorting is now largely automated through the aid of specialized machines. The first widely adopted mail sorting machine was the Transorma, first made operational in Rotterdam in 1930.

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.
