Normally, a boat's name is placed at the stern of the boat. I have never seen it placed anywhere else on the boat. I supposed you could put it up by the bow, if you wanted to, but.

A serial number is a unique identifier assigned incrementally or sequentially to an item, to uniquely identify it.
Serial numbers need not be strictly numerical. They may contain letters and other typographical symbols, or may consist entirely of a characterstring.
Applications of serial numbering[edit]
Serial numbers identify otherwise identical individual units with many, obvious uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Some items with serial numbers are automobiles, electronics, and appliances. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones.

They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected.
Serial numbers for intangible goods[edit]
Serial numbers may be used to identify individual physical or intangible objects (for example computer software or the right to play an online multiplayer game). The purpose and application is different. A software serial number, otherwise called product key, is usually not embedded in the software, but is assigned to a specific user with a right to use the software. The software will function only if a potential user enters a valid product code. The vast majority of possible codes are rejected by the software. If an unauthorised user is found to be using the software, the legitimate user can be identified from the code. It is usually not impossible, however, for an unauthorised user to create a valid but unallocated code either by trying many possible codes, or reverse engineering the software; use of unallocated codes can be monitored if the software makes an Internet connection.
Other uses of the term[edit]
The term serial number is sometimes used for codes which do not identify a single instance of something. For example, the International Standard Serial Number or ISSN used on magazines, journals and other periodicals, an equivalent to the International Standard Book Number (ISBN) applied to books, is assigned to each periodical. It takes its name from the library science use of the word serial to mean a periodical.
Certificates and certificate authorities (CA) are necessary for widespread use of cryptography. These depend on applying mathematically rigorous serial numbers and serial number arithmetic, again not identifying a single instance of the content being protected.

Military and government use[edit]
The term serial number is also used in military formations as an alternative to the expression service number.[citation needed] In air forces, the serial number is used to uniquely identify individual aircraft and is usually painted on both sides of the aircraft fuselage, most often in the tail area, although in some cases the serial is painted on the side of the aircraft's fin/rudder(s). Because of this, the serial number is sometimes called a tail number.
In the UK Royal Air Force (RAF) the individual serial takes the form of two letters followed by three digits, e.g., BT308âthe prototype Avro Lancaster, or XS903âan English Electric Lightning F.6 at one time based at RAF Binbrook.[1] During the Second World War RAF aircraft that were secret or carrying secret equipment had '/G' (for 'Guard') appended to the serial, denoting that the aircraft was to have an armed guard at all times while on the ground, e.g., LZ548/Gâthe prototype de Havilland Vampirejetfighter, or ML926/Gâa de Havilland Mosquito XVI experimentally fitted with H2S radar. Prior to this scheme the RAF, and predecessor Royal Flying Corps (RFC), utilised a serial consisting of a letter followed by four figures, e.g., D8096âa Bristol F.2 Fighter currently owned by the Shuttleworth Collection, or K5054âthe prototype Supermarine Spitfire. The serial number follows the aircraft throughout its period of service.
In 2009, the U.S. FDA published draft guidance for the pharmaceutical industry to use serial numbers on prescription drug packages.[2] This measure is intended to enhance the traceability of drugs and to help prevent counterfeiting.
What Is Another Name For The Boat's Serial Number LookupSerial number arithmetic[edit]
Serial numbers are often used in network protocols. However, most sequence numbers in computer protocols are limited to a fixed number of bits, and will wrap around after a sufficiently many numbers have been allocated. Thus, recently allocated serial numbers may duplicate very old serial numbers, but not other recently allocated serial numbers. To avoid ambiguity with these non-unique numbers, RFC1982 'Serial Number Arithmetic', defines special rules for calculations involving these kinds of serial numbers.
Lollipop sequence number spaces are a more recent and sophisticated scheme for dealing with finite-sized sequence numbers in protocols.

In the United States, all military aircraft display a serial number to identify individual aircraft. These numbers are located on the aircraft tail, so they are sometimes referred to unofficially as 'tail numbers'. On the Northrop Grumman B-2 Spirit bomber, lacking a tail, the number appears on the nose gear door. Individual agencies have each evolved their own system of serial number identification. Aircraft serials are part of the Aircraft Visual Identification System, which also includes the aircraft's tail code and Modex.
History[edit]United States Army Signal Corps[edit]
In 1908, the United States government purchased its first heavier than air aircraft. The aircraft, a Wright Model A, was used by the aviation section of the United States Army Signal Corps, and was issued with serial number 1. Subsequent aircraft were numbered in sequence.
United States Army Air Service[edit]
In 1918, the aviation section of the Army Air Service became the United States Army Air Service (USAAS), but the sequence of numbers started in 1908 continued without change. In 1920, the USAAS became independent from the Signal Corps, and by 1921 the sequence had reached 68000. On 1 July 1921, a new serial system was introduced that was based on the United States Fiscal Year, which continues to the present day. For example, the first aircraft to be procured with fiscal year 1960 funds was a Boeing B-52H serialed 60-001.

In late June 1941, when the USAAC became the United States Army Air Forces (USAAF), the sequence continued unchanged, and the displayed number, normally shown on the fixed vertical stabilizer's sides, usually omitted the first digit of the year of the contract issuance.
United States Air Force[edit]
In 1947, when the USAAF became the United States Air Force (USAF), the sequence continued unchanged. Although USAF was independent from the Army, Army aircraft continued to be allocated in the same numeric sequence until 1967.
United States Army[edit]
In 1967, the United States Army continued to use the fiscal year serials, but the numeric element was started at 15000 for each year. In 1971, the sequence was started at 20000, and was not restarted with each fiscal year.
United States Navy and Marine Corps[edit]

In 1911, the United States Navy (USN) purchased its first aircraft, a Curtiss Triad pusher floatplane. The Navy allocated a prefix for each manufacturer, and the first aircraft was serialed A-1, with A allocated to Curtiss. Different letters were also allocated to the same manufacturer, but for different types of aircraft, for example Curtiss amphibians were allocated E. In early 1914, the system was changed to a two-letter type/sub-type system, with each having a sequence starting from 1. A was allocated for heavier-than-air types for example AB was a flying boat and AX was an amphibian. All surviving aircraft from the original system were reserialled.
In 1917, the individual number sequences were stopped, and a combined sequential numerical system was started at number 51. Prefix letters were retained for a short time, but in 1917 they were replaced with single letter A for aeroplane (another name for 'airplane'). The numbers were official designating numbers, but became known as Bureau Numbers (BuNos) due to their assignment by the Navy Bureau of Aeronautics. In 1930, the service ceased using the A prefix; the last such serial was A-9204.
In 1935, when the sequence reached 9999, the sequence was restarted at 0001. At the start of the 1940s, so many aircraft were purchased that surviving aircraft from the first sequence could be confused with second-series aircraft, and the sequence was stopped at 7303.
In 1940, the third sequence was started at 00001 (with five digits). When the third sequence reached 99999, it continued with six digits which continues to date.
United States Coast Guard[edit]
In 1926, the United States Coast Guard purchased its own aircraft, and they were assigned one or two digit serial numbers. In 1934, the system was changed to a three-digit number with the first digit indicating an aircraft type. In 1936, this was changed again, and all aircraft (including those withdrawn from use) were allocated serials starting with V101. In 1945, the V prefix was removed and replaced with digit 1 to make four-digit serial numbers, which continues to the present. Since 1969, executive aircraft operated for the Secretary of the Treasury were assigned their own sequence beginning with 1.

What Is Another Name For The Boat's Serial Number Search
The early Army aircraft had large black serials marked on the fin or rudder, and in 1917 it was usual to prefix the serial with SC for signal corps, or later AS for aerial service. Later, the prefixes were not always marked, and were eventually dropped. From 1942, the serial number was applied to the fin (or boom if a helicopter) â alternatively, the North American A-36 Apache usually had its serial showing on the fuselage instead â with the first digit of the fiscal year being omitted. The serial would not be allowed to be less than four digits (for example B-45 serial number 47-007 was marked 7007), but there was no upper limit (for example YP-59A 42-108783 was marked as 2108783).
When the original fiscal year of a serial became ten years earlier than the current fiscal year, the tail number was often prefixed with a zero, for example 0-16717 instead of 16717 for UH-1H fiscal serial 66-16717. This was for disambiguation purposes, to avoid confusion with tail numbers for later fiscal years. The practice was generally abandoned in the 1980s. The notion that it was O for Obsolete is a widespread myth.[1]
In 1956, the fin serials were changed from a minimum of four digits to five digits and in 1957 all serials were limited to five digits (for example KC-135R 58-0001 is marked as 80001). The system is still in use. An aircraft in the first 10 units purchased in the fiscal year is often referred to as 'Balls-(number)' - for example, NASA's B-52B, the oldest B-52 in service until its retirement, was known as Balls 8. Aircraft that use the tactical style of marking (EX: AF80 020 to the left and below the wing tail code)are also referred to as âballsâ. This is a combination of the two consecutive zeros, one from the last digit in the build year and the other from the first digit in the aircraft number.
In 1969, camouflaged tactical aircraft were marked with modified presentation with the fiscal year followed by the last three digits of the serial number. Also, the letters AF were often added as a prefix or nearby.
Whatever the serial presentation on the fin, the full fiscal serial is always presented in a technical data block, which is normally on the port (left) side near the cockpit. Often a portion of the aircraft serial number is also painted on the aircraft nose (as is done with helicopters) or on the nose landing gear door (as is done on fighters and bombers) to help ground and air crew personnel speedily identify a certain aircraft as it approaches while taxiing into or out of parking spots or elsewhere around an airfield.
Presentation (Navy and Marine Corps)[edit]

Each Navy and Marine Corps aircraft normally has its Bureau Number plus the type designation marked in small letters on the rear fuselage. Sometimes the last four digits of the serial are painted on the fuselage or vertical stabilizer fin. Sometimes the last three digits are used as the side codes also known as nose numbers or MODEXs (most commonly in the USN P-3C Orion and P-8A Poseidon fleet), but on most operational aircraft this is normally a squadron assigned code instead of a shortened serial number.
