A BMW i3 VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number. Decode a i3 VIN here and you also get its 16 recall campaigns and 173 owner complaints filed with NHTSA — free.
How to read a BMW i3 VIN
Here is a real 2021 BMW i3 VIN from our database, split into its parts:
VIN WBY8P2C01M7J53715 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
BMW i3 VIN prefixes, and when each one was used
Characters 1–3 are the World Manufacturer Identifier. Every BMW i3 we have on record, from 2014 to 2017, carries the same one — WBY, which makes it a quick way to confirm you are looking at a real i3:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WBY | 2014–2017 | Germany | Passenger Car |
Counted from the 173 dated BMW i3 VINs attached to NHTSA complaints — the largest such set for this model — with every code checked against the NHTSA manufacturer registry, so mistyped entries are dropped; the figures say how many records carry each code, not how many i3s left the line.
Model-year codes for the BMW i3
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the BMW i3 has not yet outlived — its 8 years still map one-to-one. All 8 model years of the BMW i3, 2014 to 2021, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2021 | M | — |
| 2020 | L | — |
| 2019 | K | — |
| 2018 | J | — |
| 2017 | H | — |
| 2016 | G | — |
| 2015 | F | — |
| 2014 | E | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
Body and engine characters we see on BMW i3 VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 21 VINs the BMW i3 uses 8 different characters in these three slots alone — the ones below, ordered by how much of the BMW fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | 1 (71%) · 8 (19%) · 7 (10%) | 3 distinct |
| 5 — series | Z (81%) · P (19%) | 2 distinct |
| 8 — engine | 5 (81%) · 0 (14%) · 3 (5%) | 3 distinct |
A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.
What a decoded BMW i3 VIN gets you
Reading the characters is the easy part — the reason to decode a VIN is what sits behind it. For the BMW i3 that is 173 owner complaints and every recall campaign NHTSA has on record, keyed to the same VIN you just read:
| Data | For this model | Source |
|---|---|---|
| Recall campaigns | 16 campaigns | NHTSA |
| Owner complaints | 173 filed | NHTSA |
| Fuel economy | 77 mpg combined (avg) | EPA |
| Model years covered | 8 years | ForCar catalog |
Where to find the VIN on a BMW i3
A BMW i3 VIN normally opens with WBY. Four places on the car carry the full number, and all four must agree — on a BMW i3, a plate that disagrees is where fraud shows itself first.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tyre pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this BMW i3 VIN decoder free?
Yes — decoding a BMW i3 VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the BMW i3 — 16 recall campaigns and 173 owner complaints — at no charge.
How many characters is a BMW i3 VIN?
Seventeen, on every BMW i3 built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest BMW i3 VIN on file here is a 2014, so everything in our BMW data already uses the modern layout.
Why do two BMW i3 model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a BMW i3 VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the BMW i3 left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. What is public are the 173 complaints BMW i3 owners filed with NHTSA, and those we do show. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every BMW?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the BMW i3 can mean a different one on another BMW, and something else again on another marque. On BMW i3 VINs the character that dominates position 4 is 1 — read it against the table above, not against a generic chart.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a BMW i3 check the prefix first: for the model year in question it should open with WBY, depending on when the car was built — anything outside that set did not come off a BMW i3. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
