MPs on parliament's transport committee have rejected, at first reading, a bill that would have scrapped the engine number as a required entry on car registration certificates. Only four MPs voted for the change, none voted against, and 18 abstained.
MP Yordan Ivanov and a group of colleagues filed the bill on 30 April 2026. They argue that EU rules do not require the engine number to appear on the registration certificate at all. The car's real identifier is the chassis number, or VIN, the bill's authors say, while the engine itself can be swapped out over the years.
Ivanov and the other MPs behind the bill say the current rule is just an unnecessary burden on car owners, especially when they replace an engine with another of the same type and specs. They say dropping the requirement would make registering and re-registering cars simpler, and would mean less work for police as well.
The interior ministry, however, backs the current rules. It says engine details need to be recorded because that's what lets officials check exactly what a car is at any time, including when it's brand new.
With this vote, the bill failed to pass its first reading in committee.
