While the brand has produced diverse types of guitars since their infancy in 1833, their steel string flat-top guitars are the most sought-after. Known for their rich sound and superb build, many Martin guitars are high-ticket collectible items. Unfortunately, the market is flooded with cheap replicas that capitalize off the Martin name. This is why you have to pay attention to the Martin guitar serial numbers.

Furthermore, the company has created many different guitars with similar designs throughout its history. To ascertain a guitar’s value and authenticity, look at the serial number.

Martin Guitar Serial Numbers

The company started branding guitars with a serial number in 1898. The serial numbers begin with 8001, as the company estimated that they already had 8,000 guitars prior to 1898 in their portfolio. Martin guitar serial numbers will have between 4 and 7 serial numbers.

The most common Martin serial numbers will have 6 digits due to an influx in manufacturing quantities in the 1960s and 1970s. Serial numbers are on the neck block inside the sound hole, on the back of the head-stock, or on the neck joint. Let’s see more details depending on the guitars’ production year.

1989 – 1905: #8001 – #10120

Martin guitar serial numbers on earlier guitars are typically on the back of the head-stock. This causes used Martin guitars to show wear. Just over 2,000 guitars appeared on the market in this time.

A considerable dip in demand occurred in 1901, resulting in the company introducing a largest Martin guitar size and a 12-fret design.

1906 – 1919: #10121 – #14512

The 1-45 guitars are common in this group. They were similar in length to standard 1 sizes but featured wider sides.

During this time, the first full-sized Dreadnought guitar also appeared. So, Martin also stopped using authentic elephant ivories, instead opting for celluloid bindings and ebony bridges.

1920 – 1929: #14513 – #40843

These guitars mark the start of Martin making the switch from gut-string guitars to steel-string guitars. The OM-28 appeared in 1929, becoming the first Martin guitar with steel-string that had no modifications.

Larger sizes like the 000 are modified to accommodate 14 frets instead of the standard 12. Models with these Martin guitar serial numbers are often bigger and feature a warmer bass tone to accompany vocals.

1930 – 1939: #40844 – #74061

Martin guitar serial numbers first appeared onto the neck block in 1930. The company also began to include the model number directly above the serial number. Stamping on the head-stock officially stopped in 1935.

The famous D-45 guitars appear in this decade and start at the 53177 serial number. Used Martin guitars from this group are often the most valuable and sought-after by collectors.

1940 – 1949: #74062 – #112961

Production of the D-45 stops due to the wartime shortage of materials. Guitars in this era have a noticeable change in style. Herringbone marquetry and scalloped bracing are discontinued.

Martin serial numbers in this range include many new features, such as rosewood side strips, plastic saddles, and Micarta nuts. Replicas of older models also appeared.

These include the HD-28 and D-76. The replicas aren’t as valuable as the originals. However, they contain many original design elements like scalloped braces and herringbone.

1980 – 1989: #419901 – #493279
