(Specific to our 124 Spiders)
Note: I’ve given up on bringing my decoder to fruition, as there doesn’t appear to be a global standard in assigning VINs after all
Deciphering the 17 digits:
( ✅ = identifiers that appear to be verified and accurate)
- 1st three digits = “World Manufacturer Identifier” (“WMI”), which originally had been assigned as:
♦ 1st digit = Country of Manufacture: J for Japan ✅
♦ 2nd digit = Manufacturer: C for (Fiat Chrysler) ✅
♦ 3rd digit = (sometimes used for) Category Type: 1 for passenger car ✅
…so at least during MY 2017, Mazda, which used JM1 for MX-5’s VIN tags, assigned JC1 for the 124 Spider “WMI”. Apparently, at some point (is this a MY 2018 or 2019 thing?), they switched over to the SAE “WMI” for Fiat (ZFA) used for their other models that are produced in Italy, in place of JC1:
♦ 1st digit = Country of Manufacture: Z for Italy ✅
♦ 2nd & 3rd digits = Manufacturer: FA for (Fiat Chrysler) ✅
(Category Type not represented)
- Next 5 digits (4 through 8) = “Vehicle Description Section” (“VDS”), as configured by Mazda & Fiat:
♦ 4th & 5th digits* = Platform Brand:
NE for (Abarth brand)
NF for (Fiat brand)
…when did Abarths stop being assigned NE platform? I’m quite sure I remember readers reporting in the Fall of 2016, that their Abarths had NE assigned in their VIN, along with a different version of firmware, which is why I addended detailed information on the subject in my tweaks article. Perhaps Mazda decided to reclaim NE for the successor platform to the current NDs, now that Fiat vehicles are identified with their own WMI?
Note: Wikipedia breaks it out differently (and incorrectly, I think) as NF for North American 124 Spiders and NE for European 124 Spiders.
So it seems that lately, all models of the 124 Spider are assigned:
NF for &
♦ 6th digit* = Restraint system:
A for Driver & Passenger ~ Seat Belts, Front & Side Air Bags
6 for Driver & Passenger ~ Seat Belts, Front & Side Air Bags plus (3) Child Seat Latch Points for the passenger seat ⇒
♦ 7th digit = Body Style: E for convertible ✅
♦ 8th digit = Engine Type: K for 1.4 L Turbo ✅
- 9th digit = check digit (0 – 9, X) to legitimize the serial # ✅
- 10th digit = Model Year: ✅
H = 2017
J = 2018
K = 2019
L = 2020
M = 2021
N = 2022
- 11th digit = Assembly Plant: 0 for Hiroshima ✅
- 12th thru 17th digits = production serial # (xxxxxx) ✅
In North America, since there is no Abarth brand, other than the last six digits, the only significant digit that varied amongst our Spiders, is the 10th (Model Year), at least for MY 2017.
*[UPDATE] The first few comments have convinced me that my decoder may need further refinement, as perhaps the methodology was altered for MY 2019?
At that point, I added ✅ next to identifiers that appear to be verified and accurate, so that we know which digits to concentrate on.
Since I couldn’t find this information anywhere using Google, I reverted back to the initial decoder that I created based on Mazda’s 2016 Service Manual, but apparently things may have changed since…
Here is a Fiat version obtained by Cal that confirms my assumptions were correct, yet some inconsistencies remain…
VIN Build Sheets
To produce a vehicle build sheet for your car that lists all of the options , click on the link below and then add your VIN # to the end of the URL in the browser address bar:
Also known in the assembly plants as broadcast sheets, they were taped to the bodies coming down the line and used by workers to determine which parts were to be installed in that specific car.
VIN Window “Monroney” stickers
To produce a vehicle “Monroney” sticker for your car (if data is available, and probably only for U.S. vehicles*), click on the link below and then add your VIN # to the end of the URL in the browser address bar:
* The Monroney sticker or window sticker is a label required in the United States to be displayed in all new automobiles and includes the listing of certain official information about the car. The window sticker was named after Almer Stillwell “Mike” Monroney, United States Senator from Oklahoma.
VIN specific FIAT Spare Parts Catalog ~ FIAT KEYePER
Fiat’s Parts Explorer © “ePER” database of all of the parts specific to vehicles, currently produced in html form on USB thumb-drive “keys”, rather than printed media, and made available online on a permitted user basis, allowing you to browse all the components specific to your vehicle online (VIN # required), without needing to make a trip to your local dealer parts shop. You are encouraged to do your browsing quickly (or off-hours), as only ten users are allowed access at any given time, and you may get bounced out, should enough others choose to gain access by clicking on “OK”, when presented with the following “error” message ⇓ .
There are too many users currently connected.
If you click the OK button, one will be disconnected, and you will be allowed in.
Although a link to KEYePER is revealed in the screenshot above, if you hover north of that screenshot to find a “polar bear in a snowstorm” (I like that Cal), you’ll be able to access another actual link that azzura helped me discover. Change language as appropriate, and then enter your VIN #. Per Cal:
Directly to the right of the box you just entered your VIN into, there is a “right arrow” link. Click on the “right arrow” to proceed to the next screen and in the top right of that window is a selection button “INFO”. Click on the “INFO” button. Your vehicle’s detailed build information will now be listed.
You can’t do a CTRL-A to select all the text, but you can use your mouse to click at the beginning of the text at the very top, and then while holding the mouse down, drag it down to the bottom part of the window and it will scroll down, selecting all the text information for your build. Once you have the text selected, you can do a CTRL-C to copy all the text. Then open MS Word or your text editor of choice and CTRL-V to paste it in.
P.S. While that pop up window is still active, if you click on the NEXT button, it will take you to an interactive screen where you can search the schematics and parts for all the components on the vehicle.
