Where's my serial number?
- Late 1960s and later: usually on a small plate on the dashboard, visible through the windshield on the driver's side.
- Earlier cars: it varies by make and year. Common places are the driver's door pillar or hinge post, the steering column, the firewall, or near the glove box. Each make's page lists what our sources say.
- Paperwork: your title and registration also show it.
Example: 7810001 (an example Imperial serial).

What a Imperial serial looks like, by year
Each example below is split into numbered groups of characters, with what each group means. Example numbers show the layout; they are not a specific car.
1946
Looks like 7810001 (7 characters)
| 1 Serial number in the published Crown Imperial 8 (C-40) range for US build (7,810,001 to 7,810,166) | 7810001 [IMP] |
Where sources disagree
- This format is digits only, and many makers used plain numeric serials in these years. A match here does not by itself show the car is this make; check the make on the car and its paperwork.
Imperial Club table for 1931-1954 US-built cars: seven-digit numbers, unique by year, series and country 'but not always'. These are Chrysler-built Imperials; Imperial became a separate make in 1955.
Numeric serial number with no year character: the year is implied only by which published range the number falls in. The plant is named in the label of the matching field.

Where sources disagree
- CCV's engine-letter list for 1968-74 and 1975-80 differs from MOT/BLOG in several letters (J, K, L, N, P, U, V); the table here follows MOT and BLOG, which agree with each other for 1966 and 1971.
Car line letters are shared across makes. The make attached to each letter is inferred from the model names the sources give for it.

Where sources disagree
- Engine G: MOT also lists G as 'AMC 2.0 liter four' for 1977-79; not resolved.
- Engine J: CCV says J = 360 2-barrel for 1975-80.
- Engine K: CCV lists K as 400 4-barrel lean-burn for 1975-80.
- Engine L: CCV lists L = 360 4-barrel for 1975-80.
- Engine U: CCV lists U = 440 Six Pack.
- CCV's engine-letter list for 1968-74 and 1975-80 differs from MOT/BLOG in several letters (J, K, L, N, P, U, V); the table here follows MOT and BLOG, which agree with each other for 1966 and 1971.
Car line letters are shared across makes. The make attached to each letter is inferred from the model names the sources give for it.

What a serial number cannot tell you
It identifies what the factory recorded in the number: typically the model year, assembly plant, series or body and production sequence, and in some years the engine. It cannot confirm a car is original or numbers-matching. Compare stampings, body tags and documentation.
