Kia VIN Check
Every modern Kia VIN begins with a three-character World Manufacturer Identifier. For Kia, prefixes such as KNA, KND, 5XX tell you where the vehicle was registered as built and which corporate maker owns the code. KNA/KND indicate Korea-built Kia models; 5XX indicates the West Point, Georgia plant shared with Hyundai Motor Group.
After the WMI, positions 4–8 describe the vehicle itself — typically line, series, body, restraint, and engine — while positions 9–17 carry the check digit, model year, plant, and serial. That structure is defined by ISO 3779 and, for U.S.-market vehicles, 49 CFR Part 565.
On this page you can paste any Kia VIN into the decoder above. We check format (no I, O, or Q), verify the ISO 3779 check digit, resolve the WMI against our registry, and apply Kia-specific rules researched from NHTSA vPIC, ISO standards, and manufacturer documentation.
Kia WMI prefixes we decode
| WMI | Country | Notes |
|---|---|---|
KNA | South Korea | Cars |
KND | South Korea | SUVs |
5XX | United States | West Point, GA |
Remember: a VIN decode shows how the vehicle left the factory. It does not show accidents, title brands, odometer history, or prior owners.
How to Read a Kia VIN
Here is how DecodeAnyVin interprets a Kia VIN, and how you can read the same characters manually.
Reading a Kia VIN by hand
Positions 1–3 (WMI). Expected prefixes include KNA (South Korea), KND (South Korea), 5XX (United States). KNA/KND indicate Korea-built Kia models; 5XX indicates the West Point, Georgia plant shared with Hyundai Motor Group.
Position 4 (Vehicle Line). Common mappings in our decoder: brand-specific line codes.
Position 5. Usually series, trim, or drivetrain detail for Kia.
Position 8 (engine / related). Examples: engine / market codes that vary by year.
Position 9. ISO 3779 check digit — DecodeAnyVin validates this automatically.
Position 10. Model year on the standard 30-year letter/digit cycle.
Position 11. Assembly plant. Examples: Kia plant letters.
Positions 12–17. Production serial unique to that plant line.
Kia-specific quirks to watch
- VDS codes (4–8) can change when Kia launches a new platform — charts from a different decade may mislead.
- North American market VINs follow FMVSS 565; vehicles imported privately may still use the same WMI system but different catalog data.
- Always cross-check the decoded plant and engine against the door-jamb sticker before ordering expensive parts.
Decoded attributes are informational. Confirm engine, trim, and drivetrain against the window sticker, build sheet, or a dealer before purchase, insurance, or registration decisions.

Kia VIN Position Breakdown
| Pos. | Section | Standard Meaning | Kia Notes |
|---|---|---|---|
| 1 | WMI | Country of manufacture | ISO 3779 region code — e.g. 1=USA, J=Japan, W=Germany |
| 2 | WMI | Manufacturer | Combined with pos. 1–3 identifies Kia |
| 3 | WMI | Vehicle type | Kia WMI codes: KNA (South Korea), KND (South Korea), 5XX (United States) |
| 4 | VDS | Vehicle Line | Kia-specific model line code |
| 5 | VDS | Series / trim | Trim, series, or drive configuration |
| 6 | VDS | Body / restraint | Body style and/or restraint system (varies by year) |
| 7 | VDS | Restraint / body | Supplemental restraint or body attribute |
| 8 | VDS | Engine | Engine family or displacement code |
| 9 | Check digit | Validation | ISO 3779 weighted-sum check — detects typos and tampering |
| 10 | VIS | Model year | Standard 30-year letter/digit cycle (1980–2039) |
| 11 | VIS | Assembly plant | Kia factory code |
| 12–17 | VIS | Serial number | Unique production sequence at the assembly plant |
Frequently Asked Questions — Kia VIN
Where do I find the VIN on a Kia?
Dashboard at windshield, driver's door jamb, and on the vehicle registration documents.
What does the WMI KNA mean on a Kia?
KNA is a World Manufacturer Identifier used on Kia vehicles. KNA/KND indicate Korea-built Kia models; 5XX indicates the West Point, Georgia plant shared with Hyundai Motor Group.
How many WMI prefixes does Kia use?
Kia uses multiple WMIs depending on plant and vehicle type. In our registry you will see codes such as KNA (South Korea), KND (South Korea), 5XX (United States). The first three characters always identify the manufacturer assignment.
Can I decode a Kia VIN for free on DecodeAnyVin?
Yes. Paste your 17-character Kia VIN into the form on this page. We validate the ISO 3779 check digit, resolve the WMI, read the model year and plant, and apply Kia-specific rules for positions 4–8 where available — no signup required.
Does a Kia VIN show the engine?
Often yes. On many Kia lines, position 8 (sometimes nearby VDS positions) encodes engine family. Coverage is strongest for high-volume models such as Forte and K5; exotic or late-cycle codes may need dealer confirmation.
How do I know a Kia VIN was not altered?
Run the check digit (position 9). Example structure: 5XXGT4L370G123456. Also match the windshield VIN to the door-jamb label and reject plates that look restamped or glued. A decode cannot prove title status — only factory identity.
Is the model year on a Kia VIN always the calendar year?
No. Position 10 is the manufacturer's model year on the ISO 30-year cycle. A vehicle built in autumn may already carry next year's code. Use it as the factory model year, not the build calendar date.
Which Kia models does DecodeAnyVin support?
Any Kia with a standard 17-character VIN (typically 1981+), including Forte, K5, Sportage, Sorento, Telluride, EV6, Soul. WMI and year/plant decode work broadly; detailed trim/engine depth depends on documented VDS rules for that platform.
