“A” or a “B” in the 10th position must be newly accompanied by an alphabetic character in the
7th position, which ensures that the VIN will not be duplicative of a VIN issued for model year
vehicle 30 years ago. The agency has therefore adopted the use of “A” or “B” in the 10th
position as the trigger by which a manufacturer must apply the new requirements of today’s rule.
These new requirements will both avoid duplicate VINs and enable a VIN user to distinguish the
30 year period in which a vehicle was manufactured.
NHTSA very much appreciates the concerns expressed over the need for the timely
publication of this final rule. We believe the effective date of the rule gives regulated parties
ample time to make the changes necessary to comply with the revised requirements of Part 565.
The current VIN requirements need to be retained for an interim period during the
changeover to the new VIN requirements, for the benefit of any manufacturer that might be using
the current Part 565 VIN regulation. The agency is moving the current VIN requirements to a
subpart in part 565, and applying that regulation to vehicles manufactured between today and a
date 1 year from today’s date that do not have an “A” or “B” in the 10th position of the VIN.
Summary of Amendments Adopted in This Final Rule
The current 30 year period during which the VINs of any two vehicles subject to Part 565 may not be identical has been extended to 60 years.
A vehicle’s “make” must now be communicated in, and decipherable from, the second section of the VIN (positions 4-8), rather than being included in the manufacturer identifier.
For passenger cars and multipurpose passenger vehicles and trucks with a gross vehicle weight rating of 4536 kg. (10,000 lbs.) or less, positions 4, 5, and 6 may now be either alphabetic or numeric.
