About Cadillac
Cadillac is General Motors' flagship luxury brand, founded in 1902 in Detroit. Cadillac VINs start with 1G6 for passenger cars and 1GY for SUVs and crossovers — a clean separation that lets you tell at a glance whether a Cadillac VIN refers to a CT5 sedan or an Escalade SUV. The Lyriq, Cadillac's first dedicated EV platform, is built at Spring Hill, Tennessee with VINs prefixed 1GYKPMRL or 1GYKPMRR depending on trim.
CarWhere has 19 verified Cadillac buyer transactions with an average selling price of $86,099 and average discount of 4.9% off MSRP. Use the VIN decoder above to identify the exact Cadillac configuration, then compare it against real transaction prices.
What a Cadillac VIN Tells You
Every Cadillac VIN encodes 13 distinct vehicle attributes. Our decoder surfaces the ones that matter most for identifying, valuing, and researching a specific Cadillac:
Year
Model year — encoded in character 10 of the VIN
Model & Trim
Specific Cadillac model line and trim level
Engine
Displacement, cylinder count, and fuel type
Transmission
Automatic, manual, CVT, or DCT — and gear count
Drive Type
AWD, FWD, RWD, or 4WD configuration
Body Style
Sedan, SUV, truck, hatchback, coupe, convertible
Plant
Where this specific Cadillac was assembled
Country
Country of origin — derived from the WMI prefix
How a Cadillac VIN Is Structured
All modern Cadillac VINs follow ISO 3779 — the international 17-character VIN standard adopted in 1981. The 17 characters break into four fixed sections:
World Manufacturer Identifier (WMI)
For Cadillac, the WMI is typically 1G6, 1GY. 1G6 identifies Cadillac passenger cars (CT4, CT5). 1GY identifies Cadillac SUVs (Escalade, XT4, XT5, XT6, Lyriq).
Vehicle Descriptor Section (VDS)
Encodes the Cadillac model line, body style, restraint system, and engine. Position 8 specifically identifies the engine — the most ambiguous character because the same digit can mean different engines on different Cadillac models.
Check Digit
A mathematical checksum derived from the other 16 characters. If a Cadillac VIN doesn't pass the check-digit test, it's either a typo or a forgery.
Model Year
A single character encoding the model year. Examples on a Cadillac: L = 2020, M = 2021, N = 2022, P = 2023, R = 2024, S = 2025, T = 2026.
Plant Code
Identifies the specific Cadillac assembly plant. Cadillac operates plants in Lansing, Michigan (CT4, CT5), Arlington, Texas (Escalade), Spring Hill, Tennessee (XT5, XT6, Lyriq).
Sequential Production Number
The unique six-character serial number for that specific Cadillac unit. Two Cadillac vehicles with the same year, model, trim, and plant will differ only in this final segment.

Cadillac VIN Decoder FAQ
What does a Cadillac VIN decoder tell you?
A Cadillac VIN decoder reveals the model year, model name, trim level, engine type and displacement, transmission, drive type, body style, and assembly plant of any Cadillac vehicle. It uses the official NHTSA Vehicle Identification Number database, which every Cadillac sold in the United States is registered against. It does not show accident or ownership history.
What does a Cadillac VIN start with?
Cadillac VINs typically start with 1G6, 1GY. 1G6 identifies Cadillac passenger cars (CT4, CT5). 1GY identifies Cadillac SUVs (Escalade, XT4, XT5, XT6, Lyriq).
Where is the VIN on a Cadillac?
The easiest place to find the VIN on a Cadillac is the lower corner of the windshield on the driver's side dashboard, visible from outside the vehicle. It's also printed on the driver's door jamb sticker, the vehicle title, the registration card, and the insurance card. On older models the VIN may be stamped on the engine block or firewall.
How many characters is a Cadillac VIN?
Every Cadillac VIN is exactly 17 characters — a mix of letters and numbers. Like all modern VINs, Cadillac VINs never contain the letters I, O, or Q to avoid confusion with the digits 1, 0, and 9. A Cadillac VIN with fewer or more than 17 characters is either a partial reference or an error.
Is the Cadillac VIN decoder really free?
Yes. CarWhere's Cadillac VIN decoder is completely free with no signup, account, or credit card required. We use the NHTSA vPIC API — the official U.S. government VIN database that every U.S.-market Cadillac is filed against. We additionally cross-reference the decoded year, make, and model against verified buyer transactions in our deal database.
Where are Cadillac vehicles built?
Cadillac operates assembly plants in Lansing, Michigan (CT4, CT5), Arlington, Texas (Escalade), Spring Hill, Tennessee (XT5, XT6, Lyriq), Fairfax, Kansas (XT4). The 11th character of a Cadillac VIN identifies the specific plant of manufacture, while the first three characters (the World Manufacturer Identifier) identify the country.
Can I check Cadillac recalls by VIN?
Yes — once you decode a Cadillac VIN here, you can cross-reference open recalls at the official NHTSA recall lookup at nhtsa.gov/recalls. Cadillac also operates an owner portal where logged-in owners can view recall status and schedule free repairs at any authorized Cadillac dealer.
Does a Cadillac VIN reveal accident history?
No. A VIN decode reveals factory specifications only — make, model, trim, engine, plant. To check accident history, salvage titles, or odometer rollback on a Cadillac, you need a vehicle history report from Carfax or AutoCheck, both of which use the VIN as the lookup key but pull from insurance and DMV records.
