Where Peterbilt 348 VINs say the car was built

The first three characters are the World Manufacturer Identifier. Across 2 Peterbilt 348 VINs we have on file, these are the codes that actually show up — and the plants behind them:

Model-year codes for the Peterbilt 348

Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which for the Peterbilt 348 has already happened — 1996 and 2026 share the character T. All 46 model years of the Peterbilt 348, 1981 to 2026, with the character each one carries:

When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.

Body and engine characters we see on Peterbilt 348 VINs

Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 2 VINs the Peterbilt 348 uses 4 different characters in these three slots alone — the ones below, ordered by how much of the Peterbilt fleet each covers:

4 — body3 (100%)1 distinct
5 — seriesH (50%) · L (50%)2 distinct
8 — engineX (100%)1 distinct

A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.

Where to find the VIN on a Peterbilt 348

A Peterbilt 348 VIN normally opens with 2NP. Four places on the car carry the full number, and all four must agree — on a Peterbilt 348, a plate that disagrees is where fraud shows itself first.

Frequently asked questions

Is this Peterbilt 348 VIN decoder free?

Yes — decoding a Peterbilt 348 VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Peterbilt 348 — 69 recall campaigns — at no charge.

How many characters is a Peterbilt 348 VIN?

Seventeen, on every Peterbilt 348 built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest Peterbilt 348 VIN on file here is a 2020, so everything in our Peterbilt data already uses the modern layout.

Why do two Peterbilt 348 model years share the same VIN character?

Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. For the Peterbilt 348 that is not theoretical: a 1996 and a 2026 both carry T in position 10, and this model was built in both years. The check digit and serial range separate them.

Can a Peterbilt 348 VIN tell me if the car was in an accident?

Not from the characters themselves — they describe how the Peterbilt 348 left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. Run the number through our VIN check to see what is on the record for it.

Do the body and engine characters mean the same thing on every Peterbilt?

No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Peterbilt 348 can mean a different one on another Peterbilt, and something else again on another marque. On Peterbilt 348 VINs the character that dominates position 4 is 3 — read it against the table above, not against a generic chart.

What if the VIN on the dashboard doesn't match the door jamb?

Treat it as a red flag on any car, and on a Peterbilt 348 check the prefix first: a genuine one opens with 2NP, and a plate that starts otherwise did not come off this car. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
