Harley Davidson® VIN Identification Guide
This list is unofficial and is not gospel, only what I have been able to cross in various manuals, web sites and dealerships. If you have more updated info on this data, please let me know.
1903-1909 | 1910-1919 | 1920-1929 | 1930-1936 | 1937-1961 | 1962-1969 | 1970-1980 | 1981-2000 | 2001-2009 | 2010-Present
1970 | 1971 | 1972 | 1973 | 1974 | 1975 | 1976 | 1977 | 1978 | 1979 | 1980
- Numbers on both frame and engine. From the factory, the numbers on the frame and engine matched exactly*. (There
is an exception to this. See " The 1979 Exception" below). The legal VIN number is on the frame.
Example: 1A 13478 H7
1A = Model Designation
13478 = Sequential Number
H = Decade Code
7 = Model Season
*The 1979 Exception
- On some 1979 bikes the engine number did not match the frame number. For only about a month, starting on production date 1/9/79 frame VIN 43000H9 and ending with production date 2/7/79 frame VIN 48199H9, the engine was numbered with a "crankcase number" instead of the VIN. This number did not match the VIN in any way. After "input was received" the the new
numbering system would raise suspicion from dealers, insurance angencies, owners, cops, etc., Harley went back to the old system.
