Yamaha golf cart serial numbers: what year is it?

Yamaha is the trickiest of the big three to date, because unlike Club Car it does not stamp a readable year into the serial, and unlike E-Z-GO it does not carry a separate code with the year in it. Instead, the serial number opens with a short model code, and the year comes from matching that prefix, usually the first four characters, against Yamaha's lookup tables. This guide explains where the serial hides on each generation, which prefixes mean which model, and how to turn a prefix into a year without guessing. Once you have it, our guide to what a used Yamaha is worth picks up the story.

Where to find the serial number

Yamaha moved the serial more than any other maker, so check the locations for your era. On the early carts, the G1 through G3, it is on the frame at the rear of the vehicle, low down near the rear wheels or under the rear bumper. On the mid-era models, roughly the G8 through G16, it sits under the seat, towards the front of the vehicle where the floor meets the motor or engine compartment. On the G19 through G28 generations it moved into the driver-side glove compartment. And on the Drive, sold from 2007, it is a sticker in the motor or engine bay, typically on an upright at the rear of the vehicle on either the driver or passenger side. If the sticker has gone, a dealer can often identify the vehicle from frame numbers and photographs, so record whatever you can find.

Reading the model code

The serial's opening characters are a model code, and two independent references we cross-checked, Golf Cart Garage and Parts'n Carts, agree on the well-established ones. JN3 is the gas G14 and JN4 the electric; JN6 is the gas G16 and JN8 the electric; JR1 is the electric G19; JU0 and JU2 are the gas and electric G22; and the Drive, also known as the G29, carries JW1 and JW8 on gas vehicles and JW2 and JW9 on electric ones, with the U-MAX utility line using other JU codes. The code names the model family, but the same code spans several production years, which is why the letters alone cannot give you the year.

Turning the code into a year

The year is encoded in how the serial continues after the model code, and the honest way to decode it is a lookup rather than a formula: match the first four or so characters of your serial against a published Yamaha serial table, which parts specializts maintain, or give the full serial to a Yamaha golf car dealer, who can identify the exact model year from their systems. We would rather point you at the method than print a long table that risks dating your cart wrong: photograph the full serial plate, note the code, and check it against a current lookup or dealer. Five minutes, and it is definitive.

What the year matters for

As with any cart, three things. Parts: Yamaha listings split by model code and year, and the difference between a G16 and a G19, or an early and late Drive, decides which controllers, chargers and body parts fit. Batteries: pack layout and voltage differ across the generations, the earlier models being 36-volt and the later ones 48-volt, so the year narrows which replacement sets and lithium options apply. Value: the model year anchors the price curve described in our depreciation guide, though on older vehicles the battery age and condition matter more than the calendar. With the model and year identified, the valuation tool gives you a typical UK range in under a minute.
