An '''overprint''' is an additional layer of text or graphics added to the face of a [[Postage stamp|postage]] or [[revenue stamp]], [[postal stationery]], [[banknote]] or [[Ticket (admission)|ticket]] after it has been [[Printing|printed]].<ref>Reinfeld, p. 36.</ref><ref>Williams & Williams, p. 256.</ref> [[Post office]]s most often use overprints for internal administrative purposes such as accounting but they are also employed in public [[mail]]. Well-recognized varieties include [[Commemorative stamp|commemorative]] overprints which are produced for their public appeal and command significant interest in the field of [[philately]].<ref>{{Cite web |url=https://www.linns.com/news/postal-updates-page/stamp-collecting-basics/2002/june/surcharges-and-overprints-make-a-difference-.html |title=Surcharges and overprints make a difference |author=Klug, Janet |date=3 June 2002 |publisher=Linn's |access-date=3 September 2011 }}</ref>

== Surcharges ==
The term "surcharge" in philately describes any type of overprint that alters the price of a stamp.<ref name="Williams">Williams & Williams, p. 258.</ref> Surcharges raise or lower the face value of existing stamps when prices have changed too quickly to produce an appropriate new issue, or simply to use up surplus stocks.

Any overprint which restates a stamp's [[face value]] in a new [[currency]] is also described as a surcharge.<ref name="Williams"/> Some postal systems have resorted to surcharge overprints when converting to a new national monetary system, such as [[Postage stamps and postal history of Sierra Leone|Sierra Leone]] did when the [[Commonwealth of Nations|British Commonwealth]] converted to [[decimal currency]] in the 1960s.<ref>{{Cite book |title=Guide to Stamp Collecting |last=Klug |first=Janet |year=2008 |publisher=HarperCollins |location=New York |isbn=9780061341397 |page=[https://archive.org/details/isbn_9780061341397/page/45 45] |url=https://archive.org/details/isbn_9780061341397/page/45 |url-access=registration }}</ref>

Stamps have occasionally been overprinted multiple times. A famous example of repeated surcharging happened during the [[Hyperinflation in the Weimar Republic|German hyperinflation of 1921–1923]]. Prices rose so fast and dramatically that postage stamps which cost five or ten [[pfennig]]s in 1920 were overprinted for sale in the values of thousands, millions, and eventually billions of marks.<ref>{{Cite web |url=http://ingrimayne.com/econ/EconomicCatastrophe/HyperInflation.html |title=A Case of Inflation |author=Schenk, Robert |year=2011 |publisher=[[Saint Joseph's College (Indiana)|Saint Joseph's College]] Economics Dept. |access-date=3 September 2011 }}</ref>

== Commemorative overprints ==
Overprints have often been used as [[Commemorative stamp|commemoratives]], providing a faster and lower-cost alternative to designing and issuing special stamps or [[postmark]]s.  The [[Postage stamps and postal history of the United States|United States]], which historically has issued relatively few commemorative overprints, did this in 1928 for issues celebrating [[Molly Pitcher]] and the discovery of [[Hawaii]]. British stamps heralding the [[1966 FIFA World Cup]] were reissued after England's victory with the overprint "England Winners". Similarly, [[Postage stamps and postal history of Guyana|Guyana]] issued a set of 32 stamps showing team pictures of all the participants in the 1998 World Cup – after the tournament eight of these were reissued with an overprint announcing France's win.

In some rare cases, commemorative overprints have been applied to [[souvenir sheet]]s. When these postal commodities are overprinted, they are always very carefully positioned for aesthetic appeal, usually on the blank outer border ("[[selvage]]") of the paper.

== Change of function overprints ==
Regular stamps were also overprinted to indicate exclusive usage for a special function or combination of functions; intended for [[airmail]], [[official mail]], [[Newspaper stamp|newspapers]], [[postage due]], [[Special delivery (postal service)|special delivery]], [[Telegraph stamp|telegraph]] and so on. The official stamps of some countries like Great Britain had an overprint which defined the specific official usage; for [[Revenue stamp|inland revenue]], government parcels, office of works, [[Military stamp|military]], admiralty, [[War tax stamp|war tax]] (see below). The opposite occurs as well, in this case special function stamps are overprinted to serve as regular stamps.

== Security measures ==
Overprints have been used as security measures to deter misuse and theft.<ref>Williams & Williams, p. 253.</ref> In the nineteenth century, Mexico was plagued by thefts of stamps on their way to remote post offices. To address this, stamps were shipped from Mexico City to the local districts where they were [[Postage stamps and postal history of Mexico#District overprints|overprinted with the district name]] – they were not valid for postage without the overprint. 
 
In El Salvador a significant quantity of stamps was stolen from the San Salvador post office in 1874. As a result all remaining stock was officially overprinted 'Contrasello' preventing usage of the non-overprinted stamps.<ref>{{Cite web |url=http://www.seymourfamily.com/ElSalvadorHandbook/ |title=El Salvador Handbook - Chapter 3: 1874 - 'Contrasello' Issue |author=Gallegos, GF |year=2002 |access-date=16 June 2019 |archive-date=16 June 2019 |archive-url=https://web.archive.org/web/20190616074728/http://www.seymourfamily.com/ElSalvadorHandbook/ |url-status=dead }}</ref>

The United States used a similar strategy to deal with thefts in [[Kansas]] and [[Nebraska]] in 1929, overprinting the current [[Definitive stamp|definitive issue]] with "Kans." and "Nebr." before they were shipped from Washington, to make it more difficult to sell stolen stamps outside the indicated state.

== Colonial overprints ==
Nations overprinted stamps for use in their colonies mainly for the same reasons as for their domestic use. Due to poor planning, supply problems, faster than anticipated changing postal rates, changes in currency or other reasons they ran out of stamps, and demand had to be met. Some overprints were used to establish the first stage of postal service in a new territorial possession or colony however. If preparations had not been made, the controlling nation's regular homeland stamps would be overprinted with a local name, local currency or 'abroad' indication.  In a similar fashion a nation's domestic stamps may be overprinted for use in foreign post offices under that power's control.  For example, from 1919 to 1922 the United States overprinted 18 postage stamps at double value and marked for its office in [[Shanghai]], China.

== Provisional overprints ==
[[Provisional stamp]]s are postage issue made for temporary ''ad hoc'' usage to meet demands until regular issues are reintroduced.<ref>{{Cite web |url=http://www.linns.com/howto/refresher/classifications_20030414/refreshercourse.asp |title=Lines of stamp classifications have blurred |author=Miller, Rick |year=2011 |publisher=Linn's World Stamp Almanac |access-date=3 September 2011 |archive-url=https://web.archive.org/web/20080625213202/http://www.linns.com/howto/refresher/classifications_20030414/refreshercourse.asp |archive-date=25 June 2008 |url-status=dead }}</ref>

=== Transitional government overprints ===
New states or states in transition have sometimes found it necessary to recirculate stocks of stamps printed by a previous government. Some historical perspective may be gleaned from the study of such stamps: some transitional government overprints blend neatly with their predecessors' designs, while others attempt to totally obscure or even deface the older markings. In several European nations in 1944–45, Nazi occupational stamps were overprinted for the provisional governments, and those which depicted Adolf Hitler were most heavily overprinted, obliterating his face.

=== Wartime overprints ===
During times of war, many nations have issued [[war tax stamp]]s. Before new stamps could be printed, older stamps were frequently overprinted with surcharges or a simple inscription such as "War Tax".

In actual combat zones, the replenishment of stamp stocks is generally low on a military's list of priorities. In contested or occupied areas, captured local stamps are often expediently overprinted by the occupying forces.

</gallery>

== Precancels ==
{{main|Precancel}}
Any stamp that is cancelled by postal authorities before it is sold is described as "precancelled":<ref>Reinfeld, p.37.</ref> the precancellation mark is an overprint. This is usually only done when stamps are sold in large bulk quantities to businesses or other large organizations: the postal service will save the labor of cancelling each individual stamp by  precancelling the entire purchased quantity.<ref>Williams & Williams, p. 257.</ref> The overprints also help prevent theft or misuse because they usually include the name of the city or region in which they are to be used. Unlike standard cancellation marks, they usually do not give a specific date, affording the bulk purchaser time to use them at their discretion. In some situations, however, months or years may be included in the overprint to indicate an expiration.

Precancels for official government use are fastidiously prepared, but other kinds are almost always "heavy cancels" which deliberately obliterate much of a stamp's design.

Since the 1980s, many modern postal systems no longer use overprints to indicate bulk purchases. Bulk mail is [[Franking#Postage (stamps, etc)|franked]] using [[barcode]]s on pre-printed envelopes or on blank [[adhesive label]]s. The [[USPS]] introduced a [[Intelligent Mail barcode|new standard of barcode cancellation]] in 2011.

</gallery>

== Private overprints ==
{{main|Private overprint}}
Any overprint that does not originate from a stamp-issuing authority is considered a [[private overprint]] or [[private cancellation]]. Such overprints almost always invalidate a stamp for postal use. Most countries treat unofficial overprints the same way the [[United States Post Office]] does: the USPS Domestic Mail Manual states that stamps "overprinted with an unauthorized design, message or other marking" are not valid for postage.<ref>{{Cite web |url=http://pe.usps.com/cpim/ftp/manuals/dmm300/604.pdf |title=Domestic Mail Manual |author=USPS |year=2010 |publisher=United States Postal Service |access-date=3 September 2011 }}</ref>

Private overprints generally remain outside the formal realm of philately, although individual issues can achieve notoriety through their popularity or aesthetic appeal.  Private overprints are typically political messages or commercial promotion, but can also originate from speculative philatelic purposes produced deliberately with a view to selling them to unsuspecting collectors.

Stamps owned by commercial entities have sometimes privately overprinted the ''backs'' of their purchased stamps. These overprints are usually made as control marks or accounting information. Such overprinting does not invalidate a stamp unless it shows through the front.

== Specimen overprints ==
{{main|Specimen stamp}}
Some stamps are never valid for postal use. They are made for use in promotional displays or as reference material by postal authorities and the [[Universal Postal Union]] (UPU). Still others are manufactured by printers for [[Color management|color matching]] throughout successive printings. In all such cases, the stamps will display the word [[Specimen stamp|"specimen"]] (or "cancelled") on its face. Occasionally, the word may be uniquely handwritten by a postal authority or, much more elaborately, punched through the stamp paper in a method known as [[perfin]]. Most often, though, specimen markings are applied as a prominent overprint.<ref name="Williams"/>

== Overprints on currency ==
The design and printing of valid paper [[currency]] is rarely done hastily and overprints are extremely rare, but in times of crisis such measures have been taken. After World War I, the various successor states of the [[Austro-Hungarian Empire]] made multilingual overprints to their old Imperial currency until new notes could be designed and circulated.

Currency overprints were also used during World War II to mark all [[United States dollar]]s in the Hawaiian islands. These [[Hawaii overprint note]]s were made in case the islands were captured and the invading forces gained control of the money.<ref>{{Cite web|url=http://www.infoplease.com/askeds/bills-stamped-hawaii.html |title=Bills Stamped with Hawaii |publisher=Infoplease |date=1944-10-21 |access-date=3 September 2011 }}</ref>

Another unusual overprinting situation involving U.S. notes occurred when limited numbers of series 1935A [[silver certificate]] [[United States one-dollar bill|dollar bill]]s were overprinted with either a red "R" or an "S".  This indicated they were made of "regular" or "synthetic" paper and was a test of their wearing qualities.<ref>[http://www.uspapermoney.info/serials/all___s.html Special issue $1 notes]</ref>

The [[Haiti]]an [[Gourde]] was overprinted after the unexpectedly rapid fall of the [[Jean-Claude Duvalier|Baby Doc Duvalier]] regime.<ref>{{Cite web |url=http://www.travelinghaiti.com/haitian-currency.asp |title=Haitian Currency |year=2011 |publisher=Traveling Haiti.com |access-date=3 September 2011 }}</ref> The overprint consisted of a red circle with a slash across it with the date of the end of the Duvalier regime (7&nbsp;February 1986) printed below in red. The brusque symbol obscured the images of Baby Doc and [[François Duvalier|Papa Doc]] until they were replaced with images of figures from Haitian history. Something similar was done in [[Iran]] in 1979 when [[Mohammad Reza Pahlavi|the Shah]]'s picture was covered by an intricate design.
