, 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. With the advent of email, the retronym "snail mail" was coined. Postal authorities often have functions aside from transporting letters. In some countries, a postal, telegraph and telephone (PTT) service oversees the postal system, in addition to telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports. The Universal Postal Union (UPU), established in 1874, includes 192 member countries and sets the rules for international mail exchanges as a Specialized Agency of the United Nations.


Etymology

The word
mail
' comes from the
Middle English Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old Englis ...
word , referring to a travelling bag or pack. It was spelled in that manner until the 17th century and is distinct from the word male. The French have a similar word, , for a trunk or large box, and is the Irish term for a bag. In the 17th century, the word ''mail'' began to appear as a reference for a bag that contained letters: "bag full of letter" (1654). Over the next hundred years the word ''mail'' began to be applied strictly to the letters themselves and the sack as the ''mailbag''. In the 19th century, the British typically used ''mail'' to refer to letters being sent abroad (i.e. on a ship) and ''post'' to refer to letters for domestic delivery. The word ''Post'' is derived from Old French , which ultimately stems from the past participle of the

History

The practice of communication by written documents carried by an intermediary from one person or place to another almost certainly dates back nearly to the invention of writing. However, the development of formal postal systems occurred much later. The first documented use of an organized courier service for the dissemination of written documents is in

, where Pharaohs used couriers to send out decrees throughout the territory of the state (2400 BCE). The earliest surviving piece of mail is also Egyptian, dating to 255 BCE.


Persia (Iran)

The first credible claim for the development of a real postal system comes from Ancient Persia. The best-documented claim ( Xenophon) attributes the invention to the Persian King Cyrus the Great (550 BCE), who mandated that every province in his kingdom would organize reception and delivery of post to each of its citizens. He also negotiated with neighboring countries to do the same and had roads built from the city of Post in Western Iran all the way up to the city of Hakha in the East. Other writers credit his successor Darius I of Persia (521 BCE). Other sources claim much earlier dates for an Assyrian postal system, with credit given to Hammurabi (1700 BCE) and Sargon II (722 BCE). Mail may not have been the primary mission of this postal service, however. The role of the system as an intelligence gathering apparatus is well documented, and the service was (later) called ''angariae'', a term that in time came to indicate a tax system. The Old Testament ( Esther, VIII) makes mention of this system: Ahasuerus, king of Medes, used couriers for communicating his decisions. The Persian system worked using stations (called Chapar-Khaneh), whence the message carrier (called Chapar) would ride to the next post, whereupon he would swap his horse with a fresh one for maximum performance and delivery speed. Herodotus described the system in this way: "It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a day's journey; and these are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed". The verse prominently features on New York's James Farley Post Office, although it uses the translation "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds".


India

. The Mauryans developed early Indian mail service as well as public wells, rest houses, and other facilities for the public. Common chariots called ''Dagana'' were sometimes used as mail chariots in ancient India. Couriers were used militarily by kings and local rulers to deliver information through runners and other carriers. The postmaster, the head of the intelligence service, was responsible for ensuring the maintenance of the courier system. Couriers were also used to deliver personal letters. In South India, the

established its control over most of India. The ''Post Office Act XVII'' of 1837 provided that the Governor-General of India in Council had the exclusive right of conveying letters by post for hire within the territories of the East India Company. The mails were available to certain officials without charge, which became a controversial privilege as the years passed. On this basis the Indian Post Office was established on October 1, 1837.

but were also available for travelling officials, military men, and foreign dignitaries. These stations aided and facilitated the transport of foreign and domestic tribute specifically and the conduct of trade in general. By the end of Kublai Khan's rule, there were more than 1400 postal stations in China alone, which in turn had at their disposal about 50,000 horses, 1,400 oxen, 6,700 mules, 400 carts, 6,000 boats, more than 200 dogs, and 1,150 sheep.

Japan

The modern Japanese system was developed in the mid-19th century, closely copying European models. Japan was highly innovative in developing the world's largest and most successful postal savings system and later a postal life insurance system as well. Postmasters play a key role in linking the Japanese political system to local politics. The postmasters are high prestige, and are often hereditary. To a large extent, the postal system generated the enormous funding necessary to rapidly industrialize Japan in the late 19th century.

Modern mail

Modern mail is organized by national and privatized services, which are reciprocally connected by international regulations, organizations and international agreements. Paper letters and parcels can be sent to almost any country in the world relatively easily and cheaply. The Internet has made the process of sending letter-like messages nearly instantaneous, and in many cases and situations correspondents use email where they previously would have used letters. The volume of paper mail sent through the U.S. Postal Service has declined by more than 15% since its peak at 213 billion pieces per annum in 2006.

Payment

Before about the mid-nineteenth century, in regions where postal systems existed, the payment models varied, but most mail was sent unpaid requiring the recipient to pay the postage fee. In some regions a partial payment was made by the sender. Today, worldwide, the most common method of prepaying postage is by buying an adhesive postage stamp to be applied to the envelope before mailing; a much less common method is to use a postage-prepaid

The service provided by the U.S. Postal Service in 2003 allows the franks to be printed out on special adhesive-backed labels. In 2004 the Royal Mail in the United Kingdom introduced its ''SmartStamp'' Internet-based system, allowing printing on ordinary adhesive labels or envelopes. Similar systems are being considered by postal administrations around the world. When the pre-paid envelope or package is accepted into the mail by an agent of the postal service, the agent usually indicates by means of a cancellation that it is no longer valid for pre-payment of postage. The exceptions are when the agent forgets or neglects to cancel the mailpiece, for stamps that are pre-cancelled and thus do not require cancellation and for, in most cases, metered mail. (The "personalized stamps" authorized by the USPS and manufactured by Zazzle and other companies are in fact a form of meter label and thus do not need to be cancelled.)


Privacy and censorship

Documents should generally not be read by anyone other than the addressee; for example, in the United States of America it is a violation of federal law for anyone other than the addressee and the government to open mail. There are exceptions however: executives often assign secretaries or assistants the task of handling their mail; and postcards do not require opening and can be read by anyone. For mail contained within an envelope, there are legal provisions in some jurisdictions allowing the recording of identities of sender and recipient.Back when spies played by the rules

The mail service may be allowed to open the mail if neither addressee nor sender can be located, in order to attempt to locate either. Mail service may also open the mail to inspect if it contains materials that are hazardous to transport or violate local laws. While in most cases mail censorship is exceptional, military mail to and from soldiers is often subject to surveillance. The mail is censored to prevent leaking tactical secrets, such as troop movements or weather conditions. Depending on the country, civilian mail containing military secrets can also be monitored and censored. Mail sent to and from inmates in jails or prisons within the United States is subject to opening and review by jail or prison staff to determine if the mail has any criminal action dictated or provides means for an escape. The only mail that is not able to be read is attorney client mail, which is covered under the attorney-client confidentiality laws in the United States.

These modern alternatives have some advantages: in addition to their speed, they may be more secure, e.g., because the general public cannot learn the address of the sender or recipient from the envelope, and occasionally traditional items of mail may fail to arrive, e.g. due to vandalism to mailboxes, unfriendly pets, and adverse weather conditions. Mail carriers due to perceived hazards or inconveniences, may refuse, officially or otherwise, to deliver mail to a particular address (for instance, if there is no clear path to the door or mailbox).

Types


Letters

Letter-sized mail constitutes the bulk of the contents sent through most postal services. These are usually documents printed on A4 (210×297 mm), Letter-sized (8.5×11 inches), or smaller paper and placed in envelopes. Handwritten correspondence, while once a major means of communications between distant people, is now used less frequently due to the advent of more immediate forms of communication, such as the telephone or email. Traditional letters, however, are often considered to hark back to a "simpler time" and are still used when someone wishes to be deliberate and thoughtful about his or her communication. An example would be a letter of sympathy to a bereaved person. Bills and invoices are often sent through the mail, like regular billing correspondence from

companies and other service providers. These letters often contain a self-addressed envelope that allows the receiver to remit payment back to the company easily. While still very common, many people now opt to use online bill payment services, which eliminate the need to receive bills through the mail. Paperwork for the confirmation of large financial transactions is often sent through the mail. Many tax documents are as well. New

s), third class (bulk advertisements), and fourth-class mail (books and media packages). First-Class Mail prices are based on both the shape and weight of the item being mailed. Pieces over 13 ounces can be sent as Priority Mail. As of 2011 42% of First-Class Mail arrived the next day, 27% in two days, and 31% in three. The USPS expected that changes to the service in 2012 would cause about 51% to arrive in two days and most of the rest in three. The British Royal Mail equivalent to USPS First-Class Mail is stylized as 1st Class, and is simply a priority option over 2nd Class, at a slightly higher cost. Royal Mail aims (but does not guarantee) to deliver all 1st Class letters the day after postage. The Canada Post counterpart is Lettermail. In Austria priority delivery mail is called Prio, in Switzerland A-Post.


Registered and recorded mail

Registered mail allows the location and in particular the correct delivery of a letter to be tracked. It is usually considerably more expensive than regular mail, and is typically used for valuable items. Registered mail is constantly tracked through the system. Recorded mail is handled just like ordinary mail with the exception that it has to be signed for on receipt. This is useful for legal documents where proof of delivery is required. In the United Kingdom recorded delivery mail (branded as ''signed for'' by the Royal Mail) is covered by ''The Recorded Delivery Services Act 1962''. Under this legislation any document which its relevant law requires service by registered post can also be lawfully served by recorded delivery.

) to be attached to the outside of envelopes and bulk mailings, afterwards extending the test for an unspecified period. The repositionable note may be fixed directly to the address side of First-Class Mail and Standard Mail letter-size mailpieces. These mailpieces must meet the standards in 7.2 through 7.6. The note is included as an integral part of the mailpiece for weight and postage rate and must be accounted for in pricing.


Postal cards and postcards

s and postcards are small message cards that are sent by mail unenveloped; the distinction often, though not invariably and reliably, drawn between them is that "postal cards" are issued by the postal authority or entity with the "postal indicia" (or "stamp") preprinted on them, while postcards are privately issued and require affixing an adhesive stamp (though there have been some cases of a postal authority's issuing non-stamped postcards). Postcards are often printed to promote tourism, with pictures of resorts, tourist attractions or humorous messages on the front and allowing for a short message from the sender to be written on the back. The postage required for postcards is generally less than postage required for standard letters; however, certain technicalities such as their being oversized or having cut-outs, may result in payment of the first-class rate being required. Postcards are also used by

or third world debt cancellation).


Other mail services

Small packets are usually less than 2 kg. Larger envelopes are also sent through the mail. These are often composed of a stronger material than standard envelopes and are often used by businesses to transport documents that may not be folded or damaged, such as legal documents and contracts. Due to their size, larger envelopes are sometimes charged additional postage. Packages are often sent through some postal services, usually requiring additional postage than an average letter or postcard. Many postal services have limitations as to what a package may or may not contain, usually placing limits or bans on perishable, hazardous or flammable materials. Some hazardous materials in limited quantities may be shipped with appropriate markings and packaging, like an

s are also sent through postal services. Many magazines are simply placed in the mail normally (but in the U.S., they are printed with a special bar code that acts as pre-paid postage – see POSTNET), but many are now shipped in shrinkwrap to protect the loose contents of the magazine. During the second half of the 19th century and the first half of the 20th century, newspapers and magazines were normally posted using wrappers with a stamp imprint. Hybrid mail, sometimes referred to as L-mail, is the electronic lodgement of mail from the mail generator's computer directly to a Postal Service provider. The Postal Service provider is then able to use electronic means to have the mail piece sorted, routed and physically produced at a site closest to the delivery point. It is a type of mail growing in popularity with some Post Office operations and individual businesses venturing into this market. In some countries, these services are available to print and deliver emails to those who are unable to receive email, such as the elderly or infirm. Services provided by Hybrid mail providers are closely related to that of mail forwarding service providers.
