This page covers the modern, 2016-present Giulia (internal chassis code 952), the car actually sold new in the United States and the one nearly everyone searching “VIN decoder Alfa Romeo Giulia” owns or is shopping for. Every VIN pattern, plant code, and trim name below was checked against real, checksum-valid Giulia VINs run through NHTSA’s vPIC decoder, not guessed from a spec sheet.
About the Alfa Romeo Giulia
Quick disambiguation first, because “Giulia” has been used twice. The original Alfa Romeo Giulia (Tipo 105/115) was a rear-drive sedan sold from 1962 to 1978, mostly in Europe, and it predates the 17-character ISO VIN standard entirely. It was never sold new in the US and its chassis tags don’t decode the way a modern VIN does. If that’s the car you’re researching, use our classic car VIN decoder guide instead, since pre-1981 vehicle ID numbers follow manufacturer-specific formats rather than the standard this page covers.
Everything below is about the modern Giulia, internal code 952, which Alfa Romeo revived in 2015 and launched in Europe for the 2016 model year, with US sales starting as MY2017. It rides on the FCA Giorgio platform (also under the Stelvio) and is built at the Cassino assembly plant in Piedimonte San Germano, Italy, which also builds the Stelvio and, more recently, the Maserati Grecale. Alfa Romeo was owned by Fiat Chrysler Automobiles (FCA) at launch; FCA merged with PSA Group in January 2021 to form Stellantis, which owns Alfa Romeo today.
US-market Giulias have used a two-engine lineup for the car’s entire run: a 2.0L turbocharged inline-four (Alfa’s “GME” engine family, badged around 280 hp depending on model year) in the Giulia, Ti, Sprint, and Veloce trims, and a 2.9L twin-turbo V6 in the Quadrifoglio, developed with input from Ferrari engineers and loosely related to Ferrari’s F154 V8 architecture, rated at 505 hp and 443 lb-ft. European Giulias have also offered a 2.2L JTDM turbodiesel four-cylinder in some markets; that engine was never certified for US sale, so you will not find a diesel in a US-titled Giulia VIN.
Real decoded examples show how the trim lineup evolved. Early cars (2017-2018) decode simply as “Ti” or “Quadrifoglio.” By 2021-2023, NHTSA’s data shows Alfa consolidating and renaming trims: a confirmed 2021 VIN decodes to “Sport (Base)” rather than a plain “Giulia,” and a confirmed 2023 VIN returns a Series field listing “Ti – Lusso – Veloce – Estrema – Speciale” together, meaning that VIN pattern is shared across several trim names and the exact trim needs the build sheet to confirm. A confirmed 2024 VIN decodes to “Quadrifoglio – Quadrifoglio 100TH Anniversary,” the special edition marking Alfa Romeo’s 2010-2020 centennial.
| Model years | Confirmed trims (from real decoded VINs) | Engine | Drivetrain |
|---|---|---|---|
| 2017-2018 | Giulia, Ti, Ti Lusso, Ti Sport, Quadrifoglio | 2.0L turbo I4 or 2.9L twin-turbo V6 | RWD (AWD optional on 4-cyl) |
| 2019-2020 | Ti, Ti Sport, Quadrifoglio | 2.0L turbo I4 or 2.9L twin-turbo V6 | RWD (AWD optional on 4-cyl) |
| 2021 | Sport (Base), Ti, Quadrifoglio | 2.0L turbo I4 or 2.9L twin-turbo V6 | RWD or AWD |
| 2022-2023 | Ti, Ti Veloce, Veloce, Lusso, Estrema, Speciale | 2.0L turbo I4 | RWD or AWD |
| 2023-2024 | Quadrifoglio, Quadrifoglio 100th Anniversary | 2.9L twin-turbo V6 | RWD |
A note on honesty here: NHTSA’s “Series” field is populated from data Stellantis submits to the agency, and for several model years it returns a list of possible trim names rather than one exact answer, because trim itself isn’t fully unique to the VIN pattern; options and packages fill in the rest. Where our decoder shows a range like that, cross-check the window sticker or a build sheet if you need the exact trim.
Alfa Romeo Giulia WMI codes (positions 1 to 3)
Every US-market Giulia VIN checked for this guide, spanning model years 2017 through 2024, starts with the same World Manufacturer Identifier:
| WMI | Country | Manufacturer | Notes |
|---|---|---|---|
| ZAR | Italy | Alfa Romeo S.p.A. | All confirmed US-market Giulia VINs (2017-2024), built at Cassino/Piedimonte San Germano |
We did not find, and are not listing, any other WMI for the Giulia. Some general web sources reference other Alfa Romeo or Fiat-group WMIs, but none showed up on an actual decoded Giulia VIN during this research, so we’re leaving them out rather than guessing. If your Giulia’s VIN doesn’t start with ZAR, decode the full string with the tool at the top of this page before assuming anything is wrong. It could be a non-US Giulia built for a different market under a different WMI, or it could be a mismatched title.
How to read an Alfa Romeo Giulia VIN, position by position
Every modern Giulia uses the 17-character ISO 3779 standard adopted worldwide.
Positions 1 to 3: World Manufacturer Identifier
ZAR on every confirmed US Giulia VIN. Z marks the country of manufacture as Italy under the ISO 3780 country-code table, A identifies the manufacturer group, and R narrows it to Alfa Romeo passenger cars specifically. This block tells you the car came from an Alfa Romeo factory in Italy; it doesn’t by itself confirm which model, which the next block handles.
Positions 4 to 8: Vehicle Descriptor Section (VDS)
This is the block manufacturers use to encode body, restraint system, and engine. Position 4 on every confirmed Giulia VIN reads F, and position 5 reads A, which appear to be constants for the Giulia sedan body style rather than variables. Positions 6 and 7 vary by model year and equipment (for example, E on 2017-2018 cars, M on 2019-2021 Quadrifoglios, N on AWD four-cylinder cars from 2022 on), which most likely encode restraint-system and running-change revisions rather than anything a shopper needs to decode by hand.
Position 8 is the one worth memorizing, because it consistently tracks the engine across every VIN we checked:
| Position 8 | Engine | Confirmed on |
|---|---|---|
| N | 2.0L turbocharged inline-four | 2017-2018 Ti, 2022 Ti Veloce (AWD) |
| V | 2.9L twin-turbo V6 (Quadrifoglio) | 2017, 2019, 2020, 2024 Quadrifoglio |
Stellantis has not published an official position-by-position VDS key for the Giulia, and we’re not going to invent one for positions 6 and 7 just to fill a table. What’s above is what actually held true across every real VIN we decoded through NHTSA; if you need a full options/build-sheet breakdown, that comes from the window sticker or a dealer parts lookup, not from the VIN alone.
Position 9: Check digit
The 9th character is a computed checksum, not descriptive data. It runs the other 16 characters through a fixed weighting table and modulo-11 math defined in ISO 3779/FMVSS 565. Change any single character elsewhere in the VIN and the math breaks, which is exactly what NHTSA’s decoder, every state DMV, and this tool use to reject a mistyped or fabricated VIN before returning bad data.
Position 10: Model year
The 10th character maps to model year on a repeating 30-year cycle. For the Giulia’s actual production run, here’s the complete table with no years skipped:
| Char | Year | Char | Year | Char | Year |
|---|---|---|---|---|---|
| G | 2016 | N | 2022 | V | 2027 |
| H | 2017 | P | 2023 | W | 2028 |
| J | 2018 | R | 2024 | X | 2029 |
| K | 2019 | S | 2025 | Y | 2030 |
| L | 2020 | T | 2026 | 1 | 2031 |
| M | 2021 | 2 | 2032 |
(I, O, and Q are never used, since they’re easily confused with 1 and 0.) Every year character in this table matched the actual model year returned by NHTSA for the VINs we decoded: H on 2017 cars, J on 2018, K on 2019, L on 2020, M on 2021, N on 2022, P on 2023, and R on 2024. Since the Giulia only launched in 2016, you won’t encounter a 30-years-earlier collision on this nameplate the way you would on a longer-running model; every G you’ll ever see on a Giulia means 2016.
Position 11: Assembly plant
Every confirmed Giulia VIN we decoded, across seven model years, uses the same character here:
| Char | Plant |
|---|---|
| 7 | Cassino Assembly Plant, Piedimonte San Germano, Italy |
Interestingly, NHTSA’s own data is inconsistent about the plant’s city name: some decoded VINs return “Cassino” as Plant City and others return “Piedimonte San Germano,” the actual town where the factory sits, just south of Cassino. Both refer to the identical facility; the Giulia has only ever been built in one plant, so position 11 doesn’t vary the way it would on a nameplate assembled in multiple countries.
Positions 12 to 17: Serial number
The final six digits are the sequential production number assigned as the specific car came down the line. Combined with the preceding 11 characters, this makes every Giulia VIN globally unique, so two Quadrifoglios built the same week with identical options still carry different numbers here.
Where to find the VIN on an Alfa Romeo Giulia
- Lower-left corner of the windshield, visible through the glass from outside the car
- Driver’s side door jamb sticker (open the door and look at the B-pillar)
- Vehicle title, registration, and insurance card
- Alfa Romeo Connect app and any service or warranty paperwork from a dealer
The windshield and door jamb are the fastest to check on a car you’re about to buy; both are required by federal labeling rules and should match exactly. If they don’t match each other, or don’t match the title, treat that as a red flag and decode the VIN with the tool above before going further.
Check Alfa Romeo Giulia recalls and safety information
The Giulia has been subject to several NHTSA recall campaigns since launch. Confirmed campaigns pulled directly from NHTSA’s recall database include:
- 18V636000 (2017-2018 Giulia, 2.0L engines): possible engine misfire leading to catalytic converter overheating and wiring damage, raising fire risk.
- 18V828000 (2017-2018 AWD Giulia, GME 280hp engine): brake fluid line could contact a coolant hose clamp and leak onto the exhaust.
- 19V148000 (2017-2019 Giulia): Brake System Module software could prevent the driver from disabling Adaptive Cruise Control after a wheel-slip event.
- 23V382000 (2017-2024 Giulia): service brake hydraulic system campaign.
- A separate 2017-2019 campaign covering the fuel pump/fuel delivery system, and a 2017-2024 frontal airbag campaign, also appear in NHTSA’s records for this model.
To check your specific car:
- Decode the VIN with the tool at the top of this page to confirm the exact model year and trim.
- Search that VIN directly at NHTSA’s recall lookup.
- Contact an Alfa Romeo dealer’s service department to schedule any open campaign repair.
Recall repairs are free regardless of the car’s age, mileage, or how many owners it’s had.
Frequently asked questions
How do I decode an Alfa Romeo Giulia VIN?
Type the 17-character VIN from the windshield, door jamb, or title into the decoder at the top of this page. It returns model year, trim (or the range of possible trims for that VIN pattern), engine, drivetrain, assembly plant, and any open NHTSA recalls, in a few seconds, with no sign-up required.
Is the “Giulia” on my VIN the classic 1960s car or the modern one?
If the VIN is 17 characters and starts with ZAR, it’s the modern Giulia (2016-present, chassis code 952). The original 1962-1978 Giulia used pre-ISO chassis numbering, was never sold new in the US, and won’t decode through a standard VIN tool. If you’re working with a car from that era, use our classic car VIN decoder guide instead.
What does a Giulia VIN starting with ZAR mean?
ZAR is the World Manufacturer Identifier for Alfa Romeo S.p.A. in Italy. Every confirmed US-market Giulia VIN we checked, from 2017 through 2024, starts with this code. It confirms the car was built at an Alfa Romeo plant in Italy; the rest of the VIN narrows it down to model, year, and engine.
How can I tell if my Giulia is a Quadrifoglio from the VIN?
Check position 8. On every Quadrifoglio VIN we decoded, that character is V, corresponding to the 2.9L twin-turbo V6. Four-cylinder Giulias (Ti, Sport, Veloce, and related trims) carry N in that position instead. This isn’t an official published table from Stellantis, but it held true across every real, checksum-valid VIN we tested.
Were diesel Giulias sold in the US?
No. Alfa Romeo offered a 2.2L JTDM turbodiesel four-cylinder in some European Giulia markets, but that engine was never certified for US sale. A US-titled Giulia VIN will decode to either the 2.0L turbo four or the 2.9L twin-turbo V6, never a diesel.
Is the Alfa Romeo Giulia VIN decoder really free?
Yes. VinDecoderPlus decodes every Giulia VIN free with no account and no credit card. The basic decode covers everything the factory encoded into the VIN itself. A full vehicle history report (accident records, odometer readings, prior ownership, title brands) is available as a paid upgrade if you need one.
Can a Giulia VIN be faked or cloned?
The 17 characters themselves can be copied onto a fake plate, but the check digit at position 9 catches most single-character typos or alterations through math alone. If a seller’s windshield VIN and door-jamb VIN match each other but don’t match the title, or if the VIN decodes to a different model or year than what’s advertised, treat it as a warning sign. Our guide on how to check if a car is stolen by VIN walks through further verification steps.
