Where to find the VIN on a Nissan Altima
A Nissan Altima VIN normally opens with 1N4; the full number sits in four places, and all four must match.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Nissan Altima VIN decoder free?
Yes, with no account. Besides the year, plant and build characters it shows 65 recall campaigns and 13,494 owner complaints NHTSA holds on the Nissan Altima.
Why does my Altima VIN start differently from another Altima?
Because the Nissan Altima was built under several maker codes, by plant and period. Across the Nissan Altima VINs on record we see 3 of them: 1N4 (1993–2025), 3N1 (2002–2015), 5N1 (2004–2008). Each is genuine for its years.
What year is my Altima by its VIN?
Read position 10: a 2026 Altima carries T, a 2025 Altima carries S, a 2024 Altima carries R. A 1996 and a 2026 share T; position 7 tells them apart, a number for 1980–2009 and a letter from 2010 on.
Where was my Altima built?
Position 11 names the plant. Across 13,428 dated Nissan Altima VINs it reads C 65%, N 35%, 1 0%, 5 0% and 4 rarer codes.
What does position 4 mean on a Nissan Altima VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 426 Nissan Altima VINs here, A is the most common character in position 4, on 51% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Nissan Altima check the prefix first: most genuine ones open with 1N4. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
