BYD VIN Decoder | Dolphin, Seal & Atto VIN Decoder
Every BYD vehicle has a unique 17-character Vehicle Identification Number (VIN) that serves as its digital fingerprint. Our BYD VIN decoder reads this number and extracts detailed information directly from Chinese vehicle databases that no other decoder can access:
Engine type, body style, drivetrain, battery capacity (for EVs), trim level, and factory-installed options
Exact factory location — Shenzhen Pingshan, Xi'an, or Changsha — encoded in position 11 of the VIN
Position 10 reveals the model year (N=2022, P=2023, R=2024, S=2025, T=2026)
Chinese provincial traffic authority records and insurance claims — unavailable on Carfax or AutoCheck
Previous owners, registration history, and transfer dates from Chinese registration databases
Cross-referenced against the SAMR recall database to identify any open or closed recalls
Province of registration, registration date, deregistration status, and export clearance data
Verified against the Chinese Police Database for stolen or flagged vehicle status
Checking your BYD VIN is simple and takes less than 2 minutes. Follow this step-by-step guide to decode your BYD VIN number and access your vehicle's complete history:
Find your VIN in one of these locations: visible through the windshield on the dashboard (driver's side), on the driver's door B-pillar sticker, or stamped in the engine bay. The VIN always starts with L (manufactured in China) and is exactly 17 characters long.
Example BYD VIN: LVVDB16B*P*1234567
Scroll to the top of this page and enter your 17-character BYD VIN into the decoder widget. Make sure to enter all characters correctly — the VIN is case-sensitive. No spaces or dashes needed.
Tip: Double-check that you haven't confused 0 (zero) with O (letter O), or 1 (one) with I (letter I). VINs never use the letters I, O, or Q to avoid confusion.
Instantly see your BYD's specifications including exact model, manufacturing year, factory location, body type, engine/battery type, and trim level. This basic information is completely free and requires no registration.
The free report confirms your BYD's authenticity and helps verify the seller's claims about model year and specifications.
Our decoder cross-references your VIN against the SAMR (State Administration for Market Regulation) recall database. You'll see if your specific BYD has any open recalls, safety notices, or technical service bulletins — including recall status and affected VIN ranges.
Important: Even if a recall was issued, it may have already been completed on your vehicle. The full report shows recall completion status.
For buyers or importers, upgrade to a full paid report to access accident history from Chinese traffic authorities, ownership records, theft checks via Chinese Police Database, customs clearance status, and odometer verification from Chinese provincial records.
Full reports typically deliver within 24-48 hours via email as a downloadable PDF. Pricing starts at $9.99 for standard reports, $24.99 for premium reports with complete insurance claim history.
Our system validates your BYD VIN using the ISO 3779 check digit algorithm (position 9). We also verify the VIN against Chinese registration databases to detect cloned VINs — a common fraud tactic where stolen vehicles are given fake VIN plates from legitimate vehicles.
If the decoder shows "Invalid VIN" or data mismatches, do not proceed with the purchase. The VIN may be tampered, cloned, or incorrectly recorded.
Get instant access to your BYD's specifications, recall status, and Chinese vehicle history. Decode your VIN now — basic check is completely free.

Understanding the structure of a BYD VIN helps you verify authenticity and identify key details about the vehicle before purchase. Here is what each position means:
Note on Terminology: VIN (Vehicle Identification Number) and chassis number refer to the same 17-character code. In many countries outside North America, it's commonly called the "chassis number" or "frame number." Whether you're searching for "BYD VIN check" or "BYD chassis number check," you're looking for the same thing — the unique identifier stamped on your vehicle.
| Position(s) | Name | BYD Specific Detail |
|---|---|---|
| 1–3 | WMI Code | LGX = BYD Auto Co. (Shenzhen and other plants) |
| 4–8 | Vehicle Descriptor (VDS) | Model, body style, engine/battery type, restraint system |
| 9 | Check Digit | Mathematical verification digit (0–9 or X) |
| 10 | Model Year | N=2022 | P=2023 | R=2024 | S=2025 | T=2026 |
| 11 | Plant Code | 1=Shenzhen Pingshan | 2=Xi'an | 3=Changsha |
| 12–17 | Production Sequence | 6-digit sequential number — uniquely identifies the vehicle |
The first 3 characters of every BYD VIN are the World Manufacturer Identifier (WMI) code. BYD uses different WMI codes depending on the production plant and vehicle type. Here's what each code means:
L = China (country code)
VV = BYD Auto Co., Ltd. (Shenzhen Pingshan plant)
Used for: Most BYD passenger vehicles including Atto 3, Seal, Han, Tang, Dolphin, and Seagull manufactured at the main Shenzhen facility.
L = China
SV = BYD alternate manufacturing locations (Xi'an, Changsha, Hefei)
Used for: BYD vehicles manufactured at secondary plants, including some Qin Plus, Song Plus, and commercial vehicle models.
L = China
GX = BYD regional production identifier
Used for: Certain BYD models produced for specific export markets. Less common than LVV or LSV. If you see LGX, use our decoder to identify the exact model and specifications.
L = China
GXC = BYD commercial/industrial division
Used for: BYD electric buses, trucks, forklifts, and commercial fleet vehicles. Passenger car buyers will not encounter this code.
Your BYD's WMI code is the first 3 characters of the VIN. Look at your VIN: LVVDB16B*P*1234567.

Before decoding, you need to locate the VIN on your BYD vehicle. It can be found in these locations:
Visible through the windshield from outside the vehicle, on the lower left corner of the dashboard
Sticker located at door latch height on the B-pillar when you open the driver's door
Stamped on the firewall or chassis rail inside the engine compartment
Registration certificate (行驶证), insurance documents, and import certificate
While all BYD vehicles follow the standard VIN locations above, some models have additional placement variations or unique identifiers. Here's where to find the VIN / chassis number on popular BYD models:
Primary location: Dashboard visible through windshield on driver's side (lower left corner). Backup location: B-pillar sticker on driver's door frame — clearly marked "VIN" with barcode. Stamped location: Firewall in engine bay (accessible when hood is open, center position).
Tip: On RHD (right-hand drive) Atto 3 models sold in Australia, UK, and Thailand, the dashboard VIN is on the right side instead. All three VIN locations must match exactly.
Dashboard VIN: Visible through windshield (driver's side), same as Atto 3. Door frame sticker: B-pillar on driver's door — includes VIN, manufacturing date, tire pressure specs, and paint code. Additional location: Stamped on chassis rail under driver's seat (accessible by lifting carpet).
Note: BYD Seal's frunk (front trunk) has a service label that includes the last 8 digits of the VIN. Useful for quick verification without opening doors.
Standard locations: Dashboard (through windshield) and B-pillar sticker. Compact design note: Due to Dolphin's smaller size, the dashboard VIN may be harder to read — ensure you view it from directly outside the windshield at an angle. Backup check: Rear hatch area has a quality control sticker with VIN partial (last 6 digits).
Common issue: Dolphin dashboard VIN can fade in direct sunlight. If illegible, verify against the B-pillar sticker which is protected from UV.
Dashboard VIN: Lower left corner through windshield (may be small print due to mini car size — use phone camera zoom if needed). Door sticker: B-pillar on driver's door with full VIN, weight ratings, and manufacturing date. Chinese market note: Seagull models sold in China may have an additional VIN sticker on the rear glass.
Standard locations: Dashboard (through windshield), B-pillar door sticker, and engine bay firewall stamp. Luxury models: Han EV and Tang EV have an additional VIN engraving on the driver's side floor panel (visible when front floor mat is lifted). PHEV models: Han DM and Tang DM also have engine serial number stamped separately on the engine block.
New model (2024+): Follows standard BYD VIN placement — dashboard through windshield, B-pillar door sticker, and firewall stamp. Digital display: Sealion 7's infotainment system shows the VIN in Settings → Vehicle Info → VIN Display (useful if physical labels are damaged or hard to read).

Your BYD VIN is essential for ordering correct replacement parts. BYD uses the VIN to identify exact vehicle configuration, including region-specific parts, battery type, motor variant, and running production changes.
BYD dealers use your VIN to access the Electronic Parts Catalog (EPC). Enter your full 17-digit VIN to see part numbers, diagrams, and compatibility. Works for genuine BYD OEM parts only.
International suppliers (RockAuto, AutoZone, AliExpress) require your VIN to filter compatible parts. VIN identifies motor type (e.g., 150 kW vs 230 kW for Seal), brake size, and suspension variant.
EV-specific parts (battery modules, HV cables, motor bearings, charging ports) are VIN-specific. The VIN tells suppliers exact voltage (400V vs 800V), battery chemistry (LFP vs NMC), and motor generation.
