A letter is a written message conveyed from one person to another through a medium. Something epistolary means that it is a form of letter writing. The term usually excludes written material intended to be read in its original form by large numbers of people, such as newspapers and placards, although even these may include material in the form of an "open letter". The typical form of a letter for many centuries, and the archetypal concept even today, is a sheet of paper that is sent to a correspondent through a postal system. A letter can be formal or informal, depending on its audience and purpose. Besides being a means of communication and a store of information, letter writing has played a role in the reproduction of writing as an art throughout history. Letters have been sent since antiquity and are mentioned in the Iliad. Historians Herodotus and Thucydides mention and use letters in their writings.
A postmark is a postal marking made on an envelope, parcel, postcard or the like, indicating the place, date and time that the item was delivered into the care of a postal service, or sometimes indicating where and when received or in transit. Modern postmarks are often applied simultaneously with the cancellation or killer that marks postage stamps as having been used. Sometimes a postmark alone is used to cancel stamps, and the two terms are often used interchangeably. Postmarks may be applied by handstamp or machine, using methods such as rollers or inkjets, while digital postmarks are a recent innovation.
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.
A postal code is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.
A ZIP Code is a system of postal codes used by the United States Postal Service (USPS). The term ZIP was chosen to suggest that the mail travels more efficiently and quickly when senders use the code in the postal address.
A first day of issue cover or first day cover (FDC) is a postage stamp on a cover, postal card or stamped envelope franked on the first day the issue is authorized for use within the country or territory of the stamp-issuing authority. Sometimes the issue is made from a temporary or permanent foreign or overseas office. Covers that are postmarked at sea or their next port of call will carry a Paquebot postmark. There will usually be a first day of issue postmark, frequently a pictorial cancellation, indicating the city and date where the item was first issued, and "first day of issue" is often used to refer to this postmark. Depending on the policy of the nation issuing the stamp, official first day postmarks may sometimes be applied to covers weeks or months after the date indicated.
Postal codes used in the United Kingdom, British Overseas Territories and Crown dependencies are known as postcodes. They are alphanumeric and were adopted nationally between 11 October 1959 and 1974, having been devised by the General Post Office . The system uses alphanumeric codes to designate geographic areas. A full postcode, also known as a "postcode unit", identifies a group of addresses or a major delivery point. It consists of an outward code and inward code. The outward code indicates the area and district, while the inward code specifies the sector and delivery point, typically encompassing about 15 addresses.
Canada Post Corporation, trading as Canada Post, is a Crown corporation that functions as the primary postal operator in Canada.
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.
A Canadian postal code is a six-character string that forms part of a postal address in Canada. Like British, Irish and Dutch postcodes, Canada's postal codes are alphanumeric. They are in the format A1A 1A1, where A is a letter and 1 is a digit, with a space separating the third and fourth characters. As of October 2019, there were 876,445 postal codes using Forward Sortation Areas from A0A in Newfoundland to Y1A in Yukon.
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".
A postal marking is any kind of annotation applied to a letter by a postal service. The most common types are postmarks and cancellations; almost every letter will have those. Less common types include forwarding addresses, routing annotations, warnings, postage due notices and explanations, such as for damaged or delayed mail, and censored or inspected mail. A key part of postal history is the identification of postal markings, their purpose, and period of use.
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:
In philately, the term cover pertains to the outside of an envelope or package with an address, typically with postage stamps that have been cancelled and is a term generally used among stamp and postal history collectors. The term does not include the contents of the letter or package, although they may add interest to the item if still present. Cover collecting plays an important role in postal history as many covers bear stamps, postmarks and other markings along with names and addresses all of which help to place a cover at a given time and place in history.
The postage stamps and postal system of the Confederate States of America carried the mail of the Confederacy for a brief period in U.S. history. Early in 1861 when South Carolina no longer considered itself part of the Union and demanded that the U.S. Army abandon Fort Sumter, plans for a Confederate postal system were already underway. Indeed, the Confederate Post Office was established on February 21, 1861; and it was not until April 12 that the American Civil War officially began, when the Confederate Army fired upon U.S. soldiers who had refused to abandon the fort. However, the United States Post Office Department continued to handle the mail of the seceded states as usual during the first weeks of the war. It was not until June 1 that the Confederate Post Office took over collection and delivery, now faced with the task of providing postage stamps and mail services for its citizens.
A mail carrier, also referred to as a mailman, mailwoman, mailperson, postal carrier, postman, postwoman, postperson, person of post, letter carrier, or colloquially postie, is an employee of a post office or postal service who delivers mail and parcel post to residences and businesses. The term "mail carrier" came to be used as a gender-neutral substitute for "mailman" soon after women began performing the job. In the Royal Mail, the official name changed from "letter carrier" to "postman" in 1883, and "postwoman" has also been used for many years.
An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail.
Postcodes in Australia are used to more efficiently sort and route mail within the Australian postal system. Postcodes in Australia have four digits and are placed at the end of the Australian address, before the country. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, Australia's national postal service. Postcodes are published in booklets available from post offices or online from the Australia Post website.
El Salvador became independent from Spain in 1821. It has produced its own stamps since 1867.
