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.
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 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 United States, its insular areas, and its associated states. It is one of the 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.
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.
An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter or card.
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.
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.
A personalised (or personalized) stamp is a postage stamp on which, for a fee, an image and/or text of the purchaser's choosing may be placed. The stamps vary from country to country, and while some are normal stamps with a personalised label on the left attached by perforations, elsewhere the stamps are more properly regarded as one-piece personalised meter stamps with a colourful design next to the indicia. Stamps produced by Zazzle.com for the United States, for instance, are one-piece, self-adhesive with die cut margins to emulate perforations, and visually very similar to normal United States postage stamps, except for the addition of an information-based indicia (IBI) encoded by little black and white squares along one edge. A serial number appears next to the IBI.
Pitney Bowes Inc. is an American technology company most known for its postage meters and other mailing equipment and services, and with expansions into e-commerce, software, and other technologies. The company was founded by Arthur Pitney, who invented the first commercially available postage meter, and Walter Bowes as the Pitney Bowes Postage Meter Company on April 23, 1920.
In philately, indicia are markings on a mail piece showing that postage has been prepaid by the sender. Indicia is the plural of the Latin word indicium, meaning distinguishing marks, signs or identifying marks. The term imprinted stamp is used more or less interchangeably, but some indicia are not imprinted stamps. One example is the handstamp, which can be seen in a photo on this page.
Freepost is a postal service provided by various postal administrations, whereby a person sends mail without affixing postage, and the recipient pays the postage when collecting the mail. Freepost differs from self-addressed stamped envelopes, courtesy reply mail, and metered reply mail in that the recipient of the freepost pays only for those items that are actually received, rather than for all that are distributed. Freepost of preprinted cards issued by businesses is also different from postal stationery sold by postal administrations.
The Facing Identification Mark, or FIM, is a bar code designed by the United States Postal Service to assist in the automated processing of mail. The FIM is a set of vertical bars printed on the envelope or postcard near the upper edge, just to the left of the postage area. The FIM is intended for use primarily on preprinted envelopes and postcards and is applied by the company printing the envelopes or postcards, not by the USPS.
In philatelic terminology a letter sheet, often written lettersheet, is a sheet of paper that can be folded, usually sealed, and mailed without the use of an envelope, or it can also be a similar item of postal stationery issued by a postal authority. Letter sheets derive from the form in which written correspondence was made up before the mid-19th century—letters were written on one or more sheets of paper that were folded and sealed in such a way that the address could be written on the outside.
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.
Official mail is mail sent from, or by, an authorized department of government, governmental agency or international organization and normally has some indication that it is official; a certifying cachet, return address or other means of identity, indicating its user. In some countries, postage stamps have been issued specifically for official mail.
Arthur H. Pitney (1871–1933) was an American inventor and businessman, best known as the father of the postage meter. Pitney filed a patent application, in Stamford, Connecticut for the world’s first postage meter on December 9, 1901. He presented, demonstrated and perfected his invention over two decades – after partnering with Walter Bowes, the postage meter was approved by the U.S. Postal Service. He co-founded the Pitney-Bowes Postage Meter Company in 1920, now known as Pitney Bowes - it is a $6.1 billion provider. Pitney’s invention, the Pitney Bowes Model M Postage Meter, has been recognized as an International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.
Walter Bowes (1882–1957) was an English-born industrialist and sportsman, who came to fame in the United States as the co-founder of technology firm Pitney-Bowes Postage Meter Company
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.
A meter stamp, or meter mark, is the impression made by a postage meter machine that indicates that postage has been paid on a letter or parcel. Meter stamps are widely used by businesses and organisations as they are more efficient than using postage stamps.
