VEHICLE IDENTIFICATION NUMBER (VIN)

The Vehicle Identification Number plate (VIN) has similar information to the trim tag such as the model, year, and assembly plant. One difference is the last six numbers relating to the assembly plant sequence as opposed to the trim tag's Fisher Body sequence and the series will designate a 6-cyl (odd third digit) or V8 (even third digit) on the VIN plate where the 3rd digit on the trim tag for Baltimore and Kansas City does not but does for Fremont.

This VIN reads 136809B330131 and is for a Malibu V8 Series El Camino assembled in Baltimore, MD. and is the 30,131st Chevelle sequenced at the plant for 1969.

First Digit: Division of General Motors
1 - Chevrolet

Second and Third Digit: Series Designation
33 - El Camino 6-cylinder
34 - El Camino 8-cylinder
35 - Custom El Camino 6-cylinder
*36 - Custom El Camino, 8-cylinder

Fourth and Fifth Digit: Body Style/Model
*80 - 2-door sedan pickup

Sixth Digit: Year of Production
9 - 1969

Seventh Digit (Alpha or Numeric Designation): Final Assembly Plant
*B ~ Baltimore, Maryland
Z ~ Fremont, California
K ~ Kansas City, Missouri

Eighth through Thirteenth Digits: Sequential Production Number
The sequential starting number for the 1969 El Camino was 300001 at all El Camino assembly plants. Each assembly plant sequenced Chevelles of all series/models without regard to specific series/models. For example, if a series 13435 station wagon followed a 13667 Malibu convertible, the sequence number would be one unit higher for the wagon. It's also entirely possible to have the same sequence number from all five 1969 U.S. assembly plants (six if you include Oshawa, Ontario) with the only difference between the VINs being the plant code.

Production at the Baltimore assembly plant in July and the Kansas City plant exceeded 100,000 units in February so the VIN sequence from those time frames to the end of production would be 4nnnnn for the Baltimore and Kansas City plants.
