The NSW government has confirmed it raided the offices of Uber, the organisation behind the increasingly popular ride-sharing service UberX.

The search of Uber's offices occurred in April, about the same time the company launched the UberX ride-sharing service.

UberX has emerged since as a rapidly growing element of Sydney's transport network.

A report by the Independent Pricing and Regulatory Tribunal (IPART) this month said ride-sharing services had been used by about 11 per cent of Sydney's population in the months since April, despite the government's insistence UberX is illegal.
