Decoder reference
What this decoder page is designed to answer.
How the Thing / Type 181 chassis number is decoded
The Type 181 family is recognizable from the 18 prefix. Numeric third-position year codes cover the main 1970s production, while the later alphanumeric extension uses 18A, 18B and 18C for 1980, 1981 and 1982 in the reviewed reference. PetrolJunky handles those letter-year variants directly.
What the number does not prove
The 180 form has historical ambiguity around late-1969/1970 references, so the decoder can expose that uncertainty instead of presenting one exact year as certain. Market naming such as Thing or Trekker is also contextual rather than fully encoded in the number.
Why register the individual car
Type 181 vehicles often have military, utility or recreational histories that are not visible in the chassis code. The registry provides a place to preserve those stories alongside the sourced Volkswagen identity.

Common questions
Thing / Type 181 VIN decoder questions
What does 18A mean in a Type 181 chassis number?
In the reviewed later Type 181 reference, 18A identifies the 1980 extension; 18B and 18C correspond to 1981 and 1982.
Why can a Type 181 with 180 be year-ambiguous?
Historical references contain overlap around late-1969 and 1970 usage, so PetrolJunky preserves that ambiguity instead of forcing one year.
