To decode a Volkswagen VIN, read the first three characters for the builder and region (WVW is common on Germany-built cars; WVG shows up on some Germany-built SUVs; 3VW and 3VV are Mexico Puebla builds for cars and Tiguan; 1V2 is the Chattanooga Atlas family), then positions 4-8 for model codes, 9 for the check digit, 10 for model year, and 11 for the plant. A clean decode only shows factory build data, so pull a history report before you pay.
We spent part of mid October 2026 running VW patterns through NHTSA's free vPIC decoder, because Atlas and Tiguan shoppers still mix up Mexico and Tennessee builds, and older diesel cars still need a separate emissions paper trail. If you want the general version first, read how to decode a VIN; this page sticks to Volkswagen.
Positions 1-3: Germany, Mexico, Chattanooga
The World Manufacturer Identifier is the first filter. In our tests, a 2017 Jetta S pattern starting 3VW2B7AJ decoded as Volkswagen de Mexico in Puebla with a 1.4 TSI. A 2019 Tiguan 4Motion pattern starting 3VV2B7AX also came back Puebla, 2.0-liter. A 2019 Golf GTI pattern starting 3VW5T7AU decoded as Puebla, 2.0-liter hatchback. A 2020 Atlas SE pattern starting 1V2WR2CA decoded as Volkswagen Group of America in Chattanooga, Tennessee, 3.6-liter. A Germany-built pattern starting WVGZZZ5N returned Volkswagen AG in Wolfsburg on a partial decode. WVW Germany car patterns similarly point at Volkswagen AG plants such as Emden or Wolfsburg when the string is complete enough for vPIC.
So a US-market Tiguan often starts 3VV from Puebla, while an Atlas often starts 1V2 from Chattanooga. What should worry you is a listing that claims "German-built" when the WMI and plant say Mexico, or a VIN that does not match the door jamb. Use the checks in how to find and verify a VIN before you pay a premium for a plant story.
Positions 4-8, year, plant, and why VW codes feel dense
Volkswagen packs a lot of model information into positions 4-8, which is why forum trim charts go stale fast. Put all 17 characters into vPIC instead of decoding by hand. Our Puebla Jetta returned model Jetta, trim S, 1.4 TSI. The Puebla Tiguan returned model Tiguan with 4Motion trim lines. The Chattanooga Atlas returned model Atlas, trim SE, 3.6-liter TSI/FSI. Position 9 is the check digit under 49 CFR 565.15. Position 10 is the model year letter. Position 11 is the plant; our working decodes returned Puebla and Chattanooga clearly, with Wolfsburg on the Germany WMI samples.
A cloned VIN can still pass the check digit, so treat a perfect math result as a start, not a finish, and read our VIN cloning guide if the paperwork looks too tidy.
Diesel emissions history, then recalls and title checks
If you are looking at an older TDI, do not stop at the decode. The US diesel emissions cases are documented by the EPA's Volkswagen violations page and by the Justice Department settlement summary. Ask whether the car completed the approved modification or buyback path, and get that in writing. A seller PDF that skips the emissions section is a reason to walk. VW's own recalls page is another VIN check after the decode.
Run open recalls by VIN through NHTSA as well; our NHTSA recall check by VIN guide covers the federal lookup. For crash ratings on newer crossovers, check the IIHS Atlas ratings for the exact year. The decode still cannot show title brands, auction damage, or odometer gaps. Those come from DMV, insurance, auction, and shop records, which is what CARFAX describes as the source of its reports. Pull your own report. As of mid October 2026, a CARFAX report through us is about $5.50 as a guest or about $4.50 as a member, and a CARFAX plus AutoCheck bundle is about $6.75, against roughly $39.99 to $44.99 at retail. Confirm at checkout. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck, or Experian.
