AMSTERDAM—Dutch authorities on Thursday raided an office of Uber Technologies Inc. in Amsterdam following a ban on one of its main services, the latest setback for the car-hailing company in Europe.

Investigators of the Human Environment and Transport Inspectorate raided Uber’s office in Amsterdam’s city center, a spokeswoman for the government body said.

The investigators focused their search on Uberpop, a cheap service that was banned by a Dutch court in December because the drivers lack professional licenses required under Dutch law, the spokeswoman added.

“We want to have an idea of the total number of Uberpop drivers,” she said, without giving further details.

Uber, which is appealing the court ruling, couldn’t immediately be reached for comment.

The raid in Amsterdam follows a wider crackdown against Uber in Europe, where it has triggered a broad backlash by upending heavily regulated taxi marketplaces.

Last week, a German court slapped a nationwide ban on the Uberpop service, while French police raided Uber’s Paris office as part of a criminal probe that could shut down Uberpop in France.

Aggression against Uberpop drivers from traditional taxi drivers has also increased, resulting in several incidents in Brussels and Amsterdam in the past weeks.
