Martin Guitar Serial Numbers: Find the Year – Lookup Martin Serial
All Martin guitars since 1898 (except solidbody electrics from the 1970s, basses, and tiples) are numbered in consecutive order. Ukuleles do not have serial numbers. Mandolins use a different serial number system than guitars. Martin guitar serial numbers start at 8000 in 1898 because Martin estimated they made 8000 instruments before 1898. Model Numbers stamped above the Serial Number starting in 1930.
Starting in October 1930, Martin also stamped the model number just above the serial number. Martin model numbers are straight forward too. The first set of characters are the body size. Next there is a “-“. The last set of numbers are the ornamention style.
For example, “OO-28” stamped above the martin guitar serial number tells use the body is “OO” size (14 5/16″ wide for a 14 fret model, 14 1/8″ wide for a 12 fret model), and the ornamention style is “28” (rosewood body, ice cream cone style neck).
Left: The model and serial numbers, as seen through the sound hole on the neck block of this 1950 D-28. Prior to October 1930, the model is NOT stamped on the neck block (you have to figure it out yourself!).
Right: The model and serial numbers, as seen through the sound hole of this 1944 D-18, serial number 90067. Notice the “1” in the “18” does somewhat look like a “2”. This confuses a lot of people who think their style 18 guitar is a style 28. Also the “D” is sometimes confused for an “0”.
On round hole martin guitars, the serial and model numbers are stamped on the neck block inside the instrument. The number can be seen by looking inside the sound hole. Look at an angle towards the neck. All f-hole Martin archtops have their serial and model numbers stamped on the inside center of the backstripe, roughly under the shadow of the bridge (and best seen from the bass side “f” hole).
The numbers listed here show the LAST serial number produced for that year. Martin produced all guitar serial number sequentially. These serial number apply to all Martin guitars, flat top and arch top. It does not apply to ukes (except for the first year, they do not have a serial number). Does not apply to Martin mandolins either (they have their own serial number system).
