How to read a BMW 320i VIN
Here is a real 2018 BMW 320i VIN from our database, split into its parts:
VIN WBA8A3C50JA357745 — 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 320i VIN prefixes, and when each one was used
Every BMW 320i we have on record, from 1982 to 2015, opens with the same three characters, WBA:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WBA | 1982–2015 | Germany | Passenger Car |
Position 11 names the plant. On the BMW 320i it is not one number either — assembly moved between 4 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| N | 2014–2015 | 41 | |
| K | 2013–2015 | 21 | |
| F | 2013–2014 | 13 | |
| P | 2014–2015 | 13 |
Counted from 91 dated BMW 320i VINs attached to NHTSA complaints, each code checked against the NHTSA manufacturer registry.
Model-year codes for the BMW 320i
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which for the BMW 320i has already happened — 1987 and 2017 share the character H. All 10 model years of the BMW 320i, 1981 to 2018, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2018 | J | — |
| 2017 | H | 1987 |
| 2016 | G | — |
| 2015 | F | — |
| 2014 | E | — |
| 2013 | D | 1983 |
| 1987 | H | 2017 |
| 1983 | D | 2013 |
| 1982 | C | — |
| 1981 | B | — |
To tell the two apart on a car or light truck, look at position 7: a number for 1980–2009 models, a letter from 2010 on.

Where to find the VIN on a BMW 320i
A BMW 320i VIN normally opens with WBA; the full number sits in four places, and all four must match.
| 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 tire 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 320i VIN decoder free?
Yes, with no account. Besides the year, plant and build characters it shows 7 recall campaigns and 92 owner complaints NHTSA holds on the BMW 320i.
What year is my 320i by its VIN?
Read position 10: a 2018 320i carries J, a 2017 320i carries H, a 2016 320i carries G. A 1987 and a 2017 share H; position 7 tells them apart, a number for 1980–2009 and a letter from 2010 on.
Where was my 320i built?
Position 11 names the plant. Across 92 dated BMW 320i VINs it reads N 45%, K 23%, F 14%, P 14%.
What does position 4 mean on a BMW 320i VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 34 BMW 320i VINs here, 8 is the most common character in position 4, on 50% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a BMW 320i check the prefix first: most genuine ones open with WBA. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
