Every Hyundai Sonata (2018–2023) carries a 17-character VIN that begins with the 5NP WMI. The Sonata is a gas sedan; this page shows what each character of a Hyundai Sonata VIN means and gives 4 checksum-valid sample VINs you can drop straight into test fixtures. Synthetic — not real: no scraping, no real-owner data. The generator below is pre-filtered to the Sonata.
Each sample below is built from the real 5NP WMI and the Sonata's descriptor, so it decodes to a Hyundai Sonata of the right model year:

Worked on the sample 5NPE34AF4JH362618 — a 2018 Hyundai Sonata:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 5NP | Marks the VIN as Hyundai, built in United States |
| 4–8 | VDS | E34AF | Descriptor for the Sonata — sedan body, gas powertrain |
| 9 | Check digit | 4 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | J | Code J = 2018 |
| 11 | Plant | H | Assembly-plant code |
| 12–17 | Serial | 362618 | Sequential production number |
Positions 1–3 of every Hyundai Sonata VIN read 5NP — the World Manufacturer Identifier that marks the vehicle as Hyundai, assembled in United States (North America). After the WMI, positions 4–8 (E34AF in our seed) describe the Sonata itself; see the full 17-digit format.
Position 10 encodes the model year. For the Sonata, 2018 is code J and 2023 is code P. See the 2023 year code or the check-digit math.

A Hyundai Sonata VIN is 17 characters starting with the 5NP WMI, for example 5NPE34AF4JH362618. Positions 4–8 describe the Sonata, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 5NP is the Hyundai WMI, positions 4–8 are the Sonata descriptor, position 9 verifies the VIN via a mod-11 checksum, position 10 gives the year, position 11 the plant, and 12–17 the serial. Paste any VIN into the decoder to do it automatically.
The Sonata in our seed uses the 5NP WMI (United States). Any VIN beginning with 5NP decodes to Hyundai.
No. They are synthetically generated but checksum-valid, use the real Hyundai 5NP WMI, and carry the Sonata's descriptor and a valid year code — so a decoder returns a Hyundai Sonata. No real vehicle's VIN is used.
