'''Engine number''' may refer to an identification number marked on the engine of a vehicle or, in the case of [locomotive](/source/locomotive)s, to the [road number](/source/Running_number) of the locomotive. The engine number is separate from the [Vehicle Identification Number](/source/Vehicle_Identification_Number) (VIN).

==Automobiles==
Every vehicle [engine](/source/engine) is marked with an engine number by the factory.<ref>{{cite book |title = Small Diesel Engine Service Manual, Edition 3 |publisher = Intertec Publishing Corporation, Primedia Business Directories & Books, Intertec Publishing |page = 113 |author = Clymer Repair Manuals |year = 1991 |isbn = 978-0-87288-448-9 |url = https://books.google.com/books?id=wwamacicZjoC&q=%22engine+number%22&pg=PA113}}</ref><ref>{{cite book |url = https://books.google.com/books?id=PuhW4TC-U00C&q=engine+number+guide&pg=PA11 |page = 11 |title = Aircooled VW Engine Interchange Manual: The User's Guide to Original and Aftermarket Parts... |author = Seume, Keich |publisher = MotorBooks/MBI Publishing Company |year = 1996 |isbn = 978-0-7603-0314-6}}</ref> The engine number includes coded information, which can be decoded to reveal, for example, year of manufacture, country of manufacture, and engine type.<ref>{{cite web |url = http://www.perkins.com/cda/files/287332/7/Engine%2520Number%2520Guide%2520(PP827%2520Jan09).pdf |archive-url = https://web.archive.org/web/20090306150159/http://www.perkins.com/cda/files/287332/7/Engine%20Number%20Guide%20(PP827%20Jan09).pdf |url-status = dead |archive-date = March 6, 2009 |publisher = Perkins Engines Company Limited |year = 2009 |title = Engine Number Guide}}</ref>
