Wolverhampton City Council's Licensing Sub-Committee met on Friday (11 October) and revoked the operating licence of Westside Radio Cars, which is based in Stafford Street.
The committee heard evidence that the company had used cars that were unlicensed and uninsured.
Councillor John Reynolds, Wolverhampton City Council's Cabinet Member for City Services, said: "Ensuring public safety is of paramount importance for the council when licensing taxi drivers, vehicles and operators.
"The council does not take decisions such as revoking the licence of an existing business lightly and our licensing staff work hard to support operators to ensure they meet the relevant requirements.
"However, the safety of the public must not be compromised and when that is put at risk, we will not hesitate to take action."
The operator has 21 days to appeal the decision to Magistrates Court and may continue to trade during this period, pending any subsequent appeal.
