Uber faces bans and restrictions in many countries, including China, Switzerland, Turkey, Denmark, Hungary, Thailand, Canada, Germany, Romania, Bulgaria, Italy, Hong Kong, and parts of Australia. The bans often stem from Uber's lack of adherence to local regulations and its unfair competition with taxi services.

Uber has faced bans or severe restrictions in various global cities primarily due to regulatory conflicts, safety concerns, and opposition from traditional taxi industries. In many jurisdictions, Uber was accused of operating as an unlicensed taxi service, bypassing the strict medallion systems and high insurance requirements that traditional cabs must follow. Furthermore, legal battles over "worker classification" have led to bans; for example, in parts of Europe and the UK, courts have ruled that drivers should be treated as employees with benefits rather than independent contractors, causing Uber to temporarily exit markets where it could not comply with labor laws. Safety issues, such as inadequate background checks or "Greyball" software used to evade authorities, have also triggered bans in cities like London (which revoked its license multiple times) and various regions in Asia. In 2026, many of these "bans" have evolved into strict licensing agreements where Uber must operate under a specific legal framework that mirrors taxi regulations.
