Cadillac VIN Number Lookup — Free Decode With RPO Build Sheet, Recalls, and Title in One Shot.
Every Cadillac leaves a GM assembly line with a 17-character VIN that quietly records what engine, transmission, axle ratio, trim, and paint code the factory installed. A Cadillac VIN lookup translates that string into the same build data a dealer technician reads off the SPID label in the glove box — Cadillac is GM's luxury division and uses the identical RPO system as Chevy and GMC. Drop the VIN below and we'll decode the year, model, trim, and RPO options, then layer in open GM recalls and any title brands NMVTIS has on file. Free, instant, no sign-up.

Quick Answer
- What is a Cadillac VIN number lookup?
- A Cadillac VIN number lookup is a free tool that decodes a Cadillac's 17-character VIN into its factory build — engine RPO, transmission, axle, trim, and paint code from GM's SPID label — then layers in open GM recalls and any NMVTIS title brands, all in one search. Cadillac is General Motors' luxury division and shares the same SPID/RPO build-sheet system as Chevrolet and GMC.
- Is the Cadillac VIN lookup free?
- Yes. The lookup on this page is free with no sign-up and no card — you get decoded specs, the RPO build summary, open recalls, and a title-brand summary. A full history report with accident and mileage records is $14.99, versus about $44.99 for a single Carfax report.
- Can a VIN lookup verify a CT5-V Blackwing?
- Yes. A seller can claim Blackwing, but the SPID build sheet keyed to the VIN either lists the Blackwing supercharged LT4 RPO or it doesn't — so a lookup that surfaces RPO codes is your proof, not marketing.
What a Cadillac VIN Lookup Reveals
A Cadillac VIN carries the same dense build data as any GM vehicle. Beyond the year and model any decoder returns, a Cadillac VIN lookup paired with the SPID build sheet exposes the exact powertrain, axle, paint, and trim package that left Arlington, Lansing Grand River, or Spring Hill. Here is what comes back.
Engine + RPO code
The VIN's eighth character maps to the factory engine, and the SPID label pairs it with the three-character RPO — the 6.2L V8 L87 in an Escalade, the supercharged 6.2 LT4 in a CT5-V Blackwing, the twin-turbo 3.6 LF4 in a CT4-V Blackwing, or the 2.0T LSY and 3.0TT LGY in the CT4/CT5 and XT-series.
Transmission + axle
Decoded outputs include the GM 10-speed automatic family (10L80 behind the 2.0T/3.0TT, 10L90 behind the Blackwing and Escalade V8) and the axle ratio RPO — the difference between a rear-drive V-Series and an all-wheel-drive Premium Luxury build.
Trim + package
Luxury, Premium Luxury, Sport, Platinum on the mainstream lines; V-Series and the range-topping Blackwing on CT4 and CT5; Escalade Sport Platinum and Escalade-V. The lookup returns the factory trim and option packages encoded on the SPID.
Body + drivetrain
Standard Escalade vs. long-wheelbase Escalade ESV, sedan vs. SUV, RWD vs. AWD, and the GVWR class — all decoded from the VIN's vehicle-attribute section and the WMI (1G6 for cars, 1GY for SUVs).
Paint code + interior
Pulled from the SPID label keyed to the VIN, the paint RPO and interior trim RPO tell you whether a respray happened — useful when a listing claims original paint on a Black Raven or Radiant Red Escalade.
Plant + production sequence
Characters 11–17 identify the assembly plant — Arlington TX (Escalade), Lansing Grand River MI (CT4/CT5), Spring Hill TN (XT5/XT6/Lyriq) — and the unit's build sequence, handy when a recall is plant- or build-date-specific.
Decoding a Cadillac VIN
A Cadillac VIN follows the global ISO 3779 standard, but Cadillac's WMI prefixes and GM plant codes are worth knowing. Here's how a Cadillac VIN lookup parses the 17 characters position by position.
The first three characters are the World Manufacturer Identifier (WMI). Cadillac uses 1G6 for US-built Cadillac cars (CT4, CT5, and the legacy CTS, ATS, and XTS sedans) and 1GY for US-built Cadillac SUVs (XT4, XT5, XT6, and Escalade). The position 8 engine code and position 10 model year identify the powertrain and year (P=2023, R=2024, S=2025, T=2026).
Positions 4 through 8 are the Vehicle Descriptor Section — body style, restraint system, engine type, and series. Position 8 is the single most-decoded character on a Cadillac VIN because it separates a 2.0T LSY from a 3.0TT LGY, and a base V8 Escalade from a supercharged Escalade-V. The 9th character is the check digit; the 10th is the model year.
The 11th character is the assembly plant code, and it points to a specific Cadillac line: Arlington, Texas builds the Escalade and Escalade ESV; Lansing Grand River, Michigan builds the CT4 and CT5 (including the Blackwing V-Series); Spring Hill, Tennessee builds the XT5, XT6, and the electric Lyriq. The final six characters are the production sequence — every Cadillac gets a unique trailing serial.

How the GM Build Sheet (SPID/RPO Label) Decodes Cadillac Options
Every GM-built Cadillac carries an SPID label — the Service Parts Identification sticker — usually inside the glove box or the center console. It lists the full set of RPO (Regular Production Option) codes the factory installed: engine, transmission, axle, paint, trim, wheels, suspension (including Magnetic Ride Control), Super Cruise hardware, and every dealer-installed extra. Cadillac uses the exact same RPO system as Chevrolet and GMC, so a Cadillac VIN lookup that includes the build-sheet decode turns those three-character RPOs into plain English.
The SPID label is keyed to the VIN, which is why a build-sheet decode is so powerful on the V-Series. A seller can claim a CT5-V Blackwing, but the SPID either lists the supercharged LT4 RPO or it doesn't — and a lookup that surfaces the codes gives you the proof rather than a badge on the trunk. The same applies to a CT4-V Blackwing (twin-turbo LF4), a Platinum-trim Escalade, or a Super Cruise-equipped build (the hands-free driving RPO shows on the SPID). For a full RPO breakdown by code family, see our GM build sheet decoder.

Where to Find Your Cadillac VIN
A Cadillac VIN lookup is only as fast as you can find the VIN. Cadillac prints it in five places on every modern vehicle, and the SPID build-sheet label adds a sixth source unique to GM cars.
Lower windshield (driver side)
Look through the glass from outside, lower corner of the driver-side windshield. This is the federally mandated visible VIN — fastest to read on a CT5 or Escalade.
Driver-side door jamb sticker
Open the driver's door. The white sticker on the B-pillar lists the VIN, tire pressures, and GVWR. Required on every Cadillac by federal law.
Glove-box / console SPID label
Open the glove box or the center console and check the inside surface. The Service Parts Identification label lists the VIN plus every RPO code the factory installed.
Vehicle title document
The state-issued paper title prints the VIN at the top. On a private-party Cadillac purchase, match this against the dashboard VIN.
Insurance ID card
Your insurance card prints the VIN of every covered vehicle. Snap a photo and run the lookup before you renew or shop quotes.
myCadillac app
If the Cadillac is enrolled, the VIN appears in the vehicle profile in the myCadillac app or the OnStar account portal — useful when the car isn't in front of you.

Common Cadillac Recalls a VIN Lookup Surfaces
Cadillac shares platforms and suppliers with the rest of GM, so many of the industry's largest recall campaigns reach Cadillac VINs. A Cadillac VIN lookup queries the live NHTSA feed and the GM recall registry to surface any open campaign attached to the VIN.
Takata airbag inflator
Older Cadillac ATS, CTS, SRX, and XTS models are caught in the industry-wide Takata airbag inflator recall for inflators that can rupture. A VIN lookup against the NHTSA feed flags any open Takata campaign — the repair is free at any Cadillac dealer.
L86/LS valve spring (Escalade)
GM recalls covering certain Gen V small-block V8s addressed valve-spring fractures that could cause stalling. Escalade and Escalade ESV with the 6.2L fall within affected build ranges. A VIN lookup confirms whether the spring replacement was completed.
CUE infotainment
The Cadillac User Experience (CUE) touchscreen on older CTS, SRX, ATS, XTS, and Escalade models has been the subject of service campaigns for delamination and unresponsive screens. A VIN lookup surfaces any campaign attached to the vehicle.
Sunroof / panoramic glass
Several Cadillac campaigns have covered sunroof and panoramic-roof glass that can detach or shatter. Coverage varies by model and build date; a VIN lookup pulls the exact campaigns the car is open on.
Brake system
GM has issued brake-related campaigns — from booster and pedal issues to electronic brake-control software — that reach Cadillac sedans and SUVs. A VIN lookup confirms whether a braking campaign is open and unresolved.
Escalade seatbelt / restraint
Recent full-size SUV campaigns have covered seatbelt anchors and restraint components that may not meet spec under crash loading. The fix is a free dealer-installed repair — a VIN lookup confirms whether it's been done on a used Escalade.
Cadillac VIN Decode Quirks Worth Knowing
Most Cadillac VINs decode cleanly, but the V-Series, the Blackwing, Platinum trims, and Super Cruise hardware create build variants that live on the SPID rather than in the plain VIN. A Cadillac VIN lookup that reads the RPO codes surfaces these automatically.
Blackwing verification (proof vs. claim)
CT4-V Blackwing (twin-turbo 3.6 LF4) and CT5-V Blackwing (supercharged 6.2 LT4) command a steep premium over a standard V-Series. The engine RPO and package RPOs on the SPID are the difference between a genuine Blackwing and a V-Series with Blackwing badges — the lookup surfaces the codes so you verify, not trust.
V-Series, Platinum, and ESV
V-Series sport trims, the top-tier Platinum package, and the extended-wheelbase Escalade ESV all carry distinct RPO and body codes. A real lookup distinguishes an Escalade ESV Platinum from a standard-length Luxury build — a meaningful valuation gap on a used listing.
Super Cruise + Lyriq detection
GM's hands-free Super Cruise system is a factory RPO with dedicated hardware — a lookup that reads the SPID flags whether the car actually has it. The electric Lyriq, built at Spring Hill, decodes on its own WMI and battery-platform attributes rather than a gas-engine code.

Cadillac VIN Lookup — Frequently Asked Questions
The questions Cadillac buyers ask most when they want to look up a Cadillac VIN for the first time.
How do I look up a Cadillac VIN number?+
Find the 17-character VIN on your Cadillac — the easiest spots are the lower driver-side windshield (visible from outside), the driver-side door jamb sticker, or the SPID label inside the glove box or center console. Then paste it into the Cadillac VIN lookup form on this page. The tool validates that the VIN is exactly 17 characters and contains no I, O, or Q, then queries the decoder, the NHTSA recall feed, and NMVTIS title records in parallel. You'll see decoded specs (year, model, trim, engine, transmission, drivetrain), the RPO build summary, open GM recalls, and any title-brand history in seconds. No account required, no credit card, no hidden charges.
What does a Cadillac VIN tell me?+
A Cadillac VIN encodes the World Manufacturer Identifier (1G6 for US-built Cadillac cars like the CT4, CT5, and legacy CTS/ATS/XTS; 1GY for US-built Cadillac SUVs like the XT4/XT5/XT6 and Escalade), the body style, the restraint system, the engine family, the model year, the assembly plant, and the production sequence. Layered on top of the VIN, the GM SPID build-sheet label keyed to that VIN lists every RPO code the factory installed: exact engine RPO (L87, LT4, LF4, LSY, LGY), transmission (10L80/10L90), axle ratio, paint code, trim package (Luxury, Premium Luxury, Sport, Platinum, V, Blackwing), wheels, Magnetic Ride, Super Cruise, and any dealer-installed extras. A real Cadillac VIN lookup returns both layers.
Is the Cadillac VIN lookup free?+
Yes. The basic Cadillac VIN lookup on this page is free, with no sign-up, no credit card, and no hidden charges. You enter the 17-character Cadillac VIN and we return decoded factory specs, the RPO build summary, open GM recalls, and the title-brand summary right away. NMVTIS data and NHTSA recall data are accessible through approved providers, which is why we can offer the consumer-relevant fields for free. A full history report with every reported mileage reading and accident record is $14.99 — well under the roughly $44.99 a single Carfax report costs — but the free Cadillac VIN lookup is sufficient for most pre-purchase decisions.
How do I verify a CT5-V Blackwing by VIN?+
Run the VIN through the Cadillac VIN lookup on this page and read the SPID build sheet it surfaces. The Blackwing is defined by RPO codes — the supercharged 6.2L LT4 engine on the CT5-V Blackwing and the twin-turbo 3.6L LF4 on the CT4-V Blackwing — plus the Blackwing package RPOs. A seller can add Blackwing badges to a lesser V-Series, but the SPID label keyed to the VIN either lists the Blackwing engine and package RPOs or it doesn't. That RPO evidence, not the trunk badge, is how you confirm you're paying for a genuine Blackwing.
How do I check Cadillac recalls by VIN?+
Run the VIN through the Cadillac VIN lookup on this page. The tool queries the live NHTSA recall feed and the GM recall registry, returning any open safety campaigns attached to the VIN — Takata airbag inflator, L86/LS valve spring on the Escalade, CUE infotainment, sunroof/panoramic glass, brake, and seatbelt-anchor campaigns, plus any newer recalls. Open recalls remain attached to the VIN until the work is completed at a Cadillac dealer, and all recall repairs are free regardless of vehicle age or ownership. If a recall shows open, call any Cadillac dealership service department and schedule the fix at no charge.
How do I get RPO codes from a Cadillac VIN?+
RPO (Regular Production Option) codes aren't encoded directly into the 17-character VIN — they live on the SPID (Service Parts Identification) label GM places inside every Cadillac's glove box or center console. The SPID label is keyed to the VIN, which is why a Cadillac VIN lookup that includes build-sheet decoding can return the RPO list automatically. Engine RPOs (L87, LT4, LF4, LSY, LGY), transmission RPOs (10L80/10L90), axle RPOs, paint RPOs, and trim/package RPOs (V-Series, Blackwing, Platinum, Super Cruise) all appear on the SPID. Because Cadillac shares GM's RPO system with Chevy and GMC, our GM Build Sheet Decoder linked above translates every code family.
How do I check if a Cadillac is salvage?+
Run the VIN through the Cadillac VIN lookup on this page. The tool queries NMVTIS — the federal title aggregator that pulls from all 50 state DMVs, insurance carriers, and salvage auctions — for any salvage, junk, rebuilt, non-repairable, flood, or lemon-law title brand attached to the VIN. NMVTIS is the most authoritative single source for salvage history in the United States because federal law requires states, insurers, and salvage operators to report. If the lookup shows a salvage brand, use our dedicated salvage title check to see which brand was applied, by which state, and on which date. A clean lookup is a strong signal but not absolute — a Cadillac totaled out-of-pocket without an insurance claim may not appear, so a hands-on inspection still matters.
