Uber has had its licence suspended in Sheffield after it failed to respond to official requests about its management, the city council has said.
The firm, also fighting a ban in London, can still operate in Sheffield until 18 December and can appeal against the decision, the council said.
If it decides not to appeal, the suspension will come into force.
The taxi app firm said that an “administrative error” was to blame and hoped to resolve the issue soon.
Uber is still fighting its ban in London after it lost its licence there in September.
Transport for London, which has criticised the firm’s record over reporting criminal offences and carrying out driver background checks, decided not to renew Uber’s London licence after it deemed the firm “unfit” to run a taxi service.
A Sheffield City spokesperson said: “Uber’s licence was suspended last Friday (29 November) after the current licence holder failed to respond to requests, made by our licensing team, about the management of Uber.
“We received a new application, for a licence to operate taxis in Sheffield, from Uber Britannia Limited, on 18 October 2017 which we are currently processing.
“Any new application is dealt with by the Licensing department, who will decide if those applying for the licence meet the criteria. It will only be referred to the licensing sub-committee if a decision by the committee is required.
“The legislation does not allow for the transfer of an operator’s licence.”
An Uber spokesperson said: “We informed Sheffield City Council on 5 October that we would need to change the name on our licence as the named individual would soon be leaving the company.
“The council told us they couldn’t change the name on the licence, as most other councils have done, and that we would instead have to apply for a new one.
“We submitted an application for a new licence on 16 October which continues to be processed. While we are in regular contact with the council, we did not receive the correspondence the council refers to as they sent the letters to an incorrect address.
“We hope this administrative error can be quickly resolved so we can continue serving tens of thousands of riders and drivers in Sheffield.
“If the new application can’t be resolved by 18 December we will of course submit an appeal so we can continue to serve people in Sheffield.”
