The '''[[Denmark|Danish]] bicycle [[Vehicle Identification Number|VIN]]-system''' is a system introduced in 1942 by the Danish government, providing all [[bicycle]]s in Denmark with a unique code. The code is a combination of [[Letter (alphabet)|letters]] and [[Numerical digit|digits]] embedded into the [[bicycle frame]] and consists of a manufacturer code, a serial number, and construction year code.

Since 1948, it has been illegal<ref name='law135of1948'>{{cite web | url = https://www.retsinformation.dk/Forms/R0710.aspx?id=122988 | title = Lov nr. 135 af 23. marts 1948: Bekendtgørelse af lov om mærkning af cykelstel m.v. | accessdate = 2011-06-18 | date = 1948-03-23 | language = Danish}}</ref> to sell bicycle frames in Denmark without an embedded VIN. Because of this, insurance companies in Denmark will not pay [[Insurance claim|indemnities]] for stolen bicycles without a VIN.<ref name='dr1'>{{cite news | first = Preben | last = Lund | title = Demand for marking of stolen goods | date = 2011-06-12 | url = http://www.dr.dk/Nyheder/Indland/2011/06/12/010459.htm | work = DR Nyheder | accessdate = 2011-06-18 | language = Danish}}</ref>

By default, the VIN is to be [[Engraving|engraved]] into the [[Bicycle frame#Seat_tube|seat tube]] or the [[Bicycle frame#Down_tube|down tube]], but if these are made of such a material that hinders this, it may alternately be put on the [[Bottom bracket|bottom bracket shell]]. In very special instances, and only with the approval of the [[Rigspolitiet#Leadership|Danish National Police Commissioner’s Office]], it may be applied by other means and on other locations.<ref name="law135of1948"/>

The bicycle VIN is constructed of three elements: a letter-block, a digit-block and a letter-block:

!Description

|[[Danish bicycle VIN-system#Common_manufacturer_codes|Manufacturers code]]

|Frame serial number

|[[Danish bicycle VIN-system#Production_year_identification_codes|Production year]]

!Length

|1-4 ([[Letter (alphabet)|letters]])

|1-[[Infinity|∞]] ([[Numerical digit|digits]])

|1 (letter)

!Example 1

!Example 2

The manufacturers-code, is a 1, 2, 3 or 4-letter block. If the code starts with a W, it is an imported bicycle frame. The second block is the frame serial number from that manufacturer. This shall have at least one digit, but can otherwise have any number of digits. The third block is a single letter code that identifies the production year. Certain limits regarding letters are instated for the VIN:<ref name='askalex'>{{cite web|url=http://www.ask-alex.dk/artikler/Haandbogen/Bil-&-Cykel/Find-cyklens-alder/e_140_3644.page |archive-url=https://web.archive.org/web/20120311211953/http://www.ask-alex.dk/artikler/Haandbogen/Bil-&-Cykel/Find-cyklens-alder/e_140_3644.page |dead-url=yes |archive-date=2012-03-11 |title=How to decode the bicycles age |accessdate=2011-07-07 |author=Dansk Cyklist Forbund |language=Danish }}</ref>

* I is omitted as it can be confused with 1 (one)

* O is omitted as it can be confused with 0 (zero)

* Y is omitted as it can be confused with V

* Since 1956 Q is omitted, as it can be confused with 0 (zero)

* W is omitted, to avoid confusion with the manufacturer code (where W is reserved for imported frames)

In the examples above, the first bicycle is a bicycle imported by FDB, with serial number ''1234'' and made in either 1963, 1984 or 2005. The second bike is a SCO bicycle, with serial number ''57'', made in 1942, 1964, 1985 or 2006.
