In the case of states such as <a href="/wiki/Liberia" title="Liberia">Liberia</a> or <a href="/wiki/Panama" title="Panama">Panama</a>, which are <a href="/wiki/Flags_of_convenience" class="mw-redirect" title="Flags of convenience">flags of convenience</a> for ship registration, call signs for larger vessels consist of the national prefix plus three letters (for example, 3LXY, and sometimes followed by a number, e.g. 3LXY2). United States merchant vessels are given call signs beginning with the letters "W" or "K" while US naval ships are assigned call signs beginning with "N". Originally, both ships and broadcast stations were assigned call signs in this series consisting of three or four letters. Ships equipped with Morse code radiotelegraphy, or life boat radio sets, aviation ground stations, broadcast stations were given four-letter call signs. Maritime coast stations on high frequency (both radiotelegraphy and radiotelephony) were assigned three-letter call signs. As demand for both <a href="/wiki/Marine_radio" class="mw-redirect" title="Marine radio">marine radio</a> and broadcast call signs grew, gradually American-flagged vessels with radiotelephony only were given longer call signs with mixed letters and numbers. </p><p>Leisure craft with VHF radios may not be assigned call signs, in which case the name of the vessel is used instead. Ships in the US still wishing to have a radio license are under <a href="/wiki/Federal_Communications_Commission" title="Federal Communications Commission">FCC</a> class SA: "Ship recreational or voluntarily equipped." Those calls follow the land mobile format of the initial letter K or W followed by one or two letters followed by three or four numbers (such as KX0983 or WXX0029). <a href="/wiki/U.S._Coast_Guard" class="mw-redirect" title="U.S. Coast Guard">U.S. Coast Guard</a> small boats have a number that is shown on both bows (i.e. port and starboard) in which the first two digits indicate the nominal length of the boat in feet. For example, Coast Guard 47021 refers to the 21st in the series of 47-foot motor lifeboats. The call sign might be abbreviated to the final two or three numbers during operations, for example: <i>Coast Guard zero two one</i>. </p> <div class="mw-heading mw-heading3"><h3 id="Aviation">Aviation</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Call_sign&amp;action=edit&amp;section=3" title="Edit section: Aviation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951" /><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Aviation_call_signs" title="Aviation call signs">Aviation call signs</a></div> <p>Originally aviation mobile stations (aircraft) equipped with radiotelegraphy were assigned five-letter call signs (e.g. KHAAQ). Land stations in aviation were assigned four-letter call signs (e.g. WEAL &#8211; Eastern Air Lines, NYC.) These call signs were phased out in the 1960s when <a href="/w/index.php?title=Flight_radio_officer&amp;action=edit&amp;redlink=1" class="new" title="Flight radio officer (page does not exist)">flight radio officers</a> (FRO) were no longer required on international flights. The Russian Federation kept FROs for the Moscow-Havana run until around 2000. </p><p>Currently, all signs in <a href="/wiki/Aviation" title="Aviation">aviation</a> are derived from several different policies, depending upon the type of flight operation and whether or not the caller is in an aircraft or at a ground facility. In most countries, unscheduled <a href="/wiki/General_aviation" title="General aviation">general aviation</a> flights identify themselves using the call sign corresponding to the <a href="/wiki/Aircraft_registration" title="Aircraft registration">aircraft's registration</a> number (also called <i>N-number</i> in the U.S., or <i>tail number</i>). In this case, the call sign is spoken using the <a href="/wiki/International_Civil_Aviation_Organization" title="International Civil Aviation Organization">International Civil Aviation Organization</a> (ICAO) <a href="/wiki/NATO_phonetic_alphabet" title="NATO phonetic alphabet">phonetic alphabet</a>. Aircraft registration numbers internationally follow the pattern of a country prefix, followed by a unique identifier made up of letters and numbers. For example, an aircraft registered as <i>N978CP</i> conducting a <a href="/wiki/General_aviation" title="General aviation">general aviation</a> flight would use the call sign <i>November-niner-seven-eight-Charlie-Papa</i>. However, in the United States a pilot of an aircraft would normally omit saying <i>November</i>, and instead use the name of the aircraft manufacturer or the specific model. At times, general aviation pilots might omit additional preceding numbers and use only the last three numbers and letters. This is especially true at uncontrolled fields (those without control towers) when reporting traffic pattern positions or at towered airports after establishing two-way communication with the tower controller. For example, <i>Skyhawk eight-Charlie-Papa, left base</i>. In commercial aviation, the callsign is usually the ICAO <a href="/wiki/Flight_number" title="Flight number">Flight number</a>. For example, <i>Delta Airlines Flight 744</i> would have the flight number <i>DL744</i> and the callsign would be <i>Delta 744</i>. </p><p>In most countries, the aircraft call sign or "tail number"/"tail letters" (also known as registration marks) are linked to the international radio call sign allocation table and follow a convention that aircraft radio stations (and, by extension, the aircraft itself) receive call signs consisting of five letters. For example, all British <a href="/wiki/Civil_aviation" title="Civil aviation">civil aircraft</a> have a five-letter registration beginning with the letter G, which can also serve for a call sign. Canadian aircraft have a call sign beginning with C–F or C–G, such as C–FABC. <a href="/wiki/Ground-effect_vehicle" title="Ground-effect vehicle">wing-in-ground-effect vehicles</a> and <a href="/wiki/Hovercraft" title="Hovercraft">hovercraft</a> in Canada are eligible to receive C–Hxxx call signs, and <a href="/wiki/Ultralight_aviation" title="Ultralight aviation">ultralight aircraft</a> receive C-Ixxx call signs. In days gone by, even American aircraft used five-letter call signs, such as KH–ABC, but they were replaced prior to World War II by the current American system of civilian aircraft call signs (see below). One exception to the parallelism between registration and call sign is ultralight airplanes in France, who are not obliged to carry a radio and indeed often don't. </p> <div class="mw-heading mw-heading3"><h3 id="Spaceflight">Spaceflight</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Call_sign&amp;action=edit&amp;section=4" title="Edit section: Spaceflight"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951" /><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Spacecraft_call_signs" title="Spacecraft call signs">Spacecraft call signs</a></div> <p>Radio call signs used for communication in crewed spaceflight are not formalized or regulated to the same degree as for aircraft.

Some stations still broadcast their call signs a few times a day, but this practice is becoming very rare. Argentinian broadcast call signs consist of two or three letters followed by multiple numbers, the second and third letters indicating region. In Brazil, radio and TV stations are identified by a ZY, a third letter and three numbers. <i>ZYA</i> and <i>ZYB</i> are allocated to television stations; <i>ZYI</i>, <i>ZYJ</i>, <i>ZYL</i>, and <i>ZYK</i> designate AM stations; <i>ZYG</i> is used for <a href="/wiki/Shortwave" class="mw-redirect" title="Shortwave">shortwave</a> stations; <i>ZYC</i>, <i>ZYD</i>, <i>ZYM</i>, and <i>ZYU</i> are given to FM stations. </p><p>In Australia, broadcast call signs are optional, but are allocated by the <a href="/wiki/Australian_Communications_and_Media_Authority" title="Australian Communications and Media Authority">Australian Communications and Media Authority</a> and are unique for each broadcast station. </p><p>Most European and Asian countries do not use call signs to identify broadcast stations, but Japan, South Korea, Indonesia, the Philippines and Taiwan do have call sign systems. Spanish broadcasters used call signs consisting of <i>E</i> followed by two letters and up to three digits until the late 1970s. Portugal had a similar system, their callsigns beginning with <i>C</i>; these also ceased to be used in the 1970s. Britain has no call signs in the American sense, but allows broadcast stations to choose their own <a href="/wiki/Trade_mark" class="mw-redirect" title="Trade mark">trade mark</a> call sign up to six words in length. </p> <div class="mw-heading mw-heading2"><h2 id="Amateur_radio">Amateur radio</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Call_sign&amp;action=edit&amp;section=6" title="Edit section: Amateur radio"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951" /><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Amateur_radio_call_signs" title="Amateur radio call signs">Amateur radio call signs</a></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Reg_plate_california.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/7e/Reg_plate_california.jpg/220px-Reg_plate_california.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/7e/Reg_plate_california.jpg/330px-Reg_plate_california.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/7e/Reg_plate_california.jpg/440px-Reg_plate_california.jpg 2x" data-file-width="1000" data-file-height="667" /></a><figcaption>All U.S. states issue call sign <a href="/wiki/License_plate" class="mw-redirect" title="License plate">license plates</a> upon request for motor vehicles owned by amateur radio operators; this road vehicle is from <a href="/wiki/California" title="California">California</a>.</figcaption></figure> <p><a href="/wiki/Amateur_radio" title="Amateur radio">Amateur radio</a> call signs are in the international series and normally consist of a one or two character prefix, a digit (which may be used to denote a geographical area, class of license, or identify a licensee as a visitor or temporary resident), and a 1-, 2-, or 3-letter suffix. In Australia, call signs are structured with a two letter prefix, a digit (which identifies geographical area), and a 2, 3 or 4 letter suffix. This suffix may be followed by a further suffix, or personal identifier, such as /P (portable), /M (mobile), /AM (aeronautical mobile) or /MM (maritime mobile). The number following the prefix is normally a single number (0 to 9). Some prefixes, such as Djibouti's (J2), consist of a letter followed by a number. Hence, in the hypothetical Djibouti call sign, J29DBA, the prefix is <i>J2</i>, the number is <i>9</i>, and the suffix is <i>DBA</i>. Others may start with a number followed by a letter, for example, Jamaican call signs begin with 6Y. </p><p>When operating with reciprocal agreements under the jurisdiction of a foreign government, an identifying station pre-pends the call sign with the country prefix and number of the country/territory from which the operation is occurring. For example, W4/G3ABC would denote a licensed amateur from the United Kingdom who is operating in the fourth district of the United States. There are exceptions; in the case of U.S./Canadian reciprocal operations, the country/territory identifier is, instead, appended to the call sign; e.g., W1AW/VE4, or VE3XYZ/W1. </p><p>Special call signs are issued in the amateur radio service either for special purposes, VIPs, or for temporary use to commemorate special events. Examples include <i>VO1S</i> (<i>VO1</i> as a <a href="/wiki/Dominion_of_Newfoundland" title="Dominion of Newfoundland">Dominion of Newfoundland</a> call sign prefix, <i>S</i> to commemorate <a href="/wiki/Guglielmo_Marconi" title="Guglielmo Marconi">Marconi</a>'s first trans-Atlantic message, a single-character <a href="/wiki/Morse_code" title="Morse code">Morse code</a> <i>S</i> sent from <a href="/wiki/Cornwall" title="Cornwall">Cornwall</a>, England to Signal Hill, <a href="/wiki/St._John%27s,_Newfoundland_and_Labrador" title="St. John&#39;s, Newfoundland and Labrador">St. John's</a> in 1901) and GB90MGY (<i>GB</i> as a Great Britain call sign prefix, <i>90</i> and <i>MGY</i> to commemorate the 90th anniversary of historic 1912 radio <a href="/wiki/Distress_call" class="mw-redirect" title="Distress call">distress calls</a> from <i>MGY</i>, the <a href="/wiki/Marconi_Station" class="mw-redirect" title="Marconi Station">Marconi station</a> aboard the famed <a href="/wiki/White_Star_Line" title="White Star Line">White Star</a> luxury liner <a href="/wiki/RMS_Titanic" class="mw-redirect" title="RMS Titanic">RMS <i>Titanic</i></a>).<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> </p><p>The late <a href="/wiki/Hussein_of_Jordan" title="Hussein of Jordan">King Hussein</a> of <a href="/wiki/Jordan" title="Jordan">Jordan</a> was issued a special amateur license number, <b>JY1</b>, which would have been the shortest possible call sign issued by the Hashemite Kingdom of Jordan. </p><p>When identifying a station by voice, the call sign may be given by simply stating the letters and numbers, or using a <a href="/wiki/NATO_phonetic_alphabet" title="NATO phonetic alphabet">phonetic alphabet</a>.
