The government body responsible for all transport within the English capital withdrew the ride-hailing app's operating license in September last year amid concerns about "public safety and security implications".
Uber is currently appealing against the decision, and has now made a range of amendments to its app ahead of the company's hearing in June, which will see a final decision made on their license.
In a blog post on Uber's website, the app developers stated that rides will now be accepted before allocating drivers, and only drivers licensed to be a private hire driver in London will be able to operate within that region.
They said: "From today, we will make it clearer to riders in London - once they have requested a car through our app - that Uber London has accepted their booking as the private hire operator.
"All bookings through our app in London and surrounding areas (such as at airports like Heathrow) will be accepted by Uber London, which means that only drivers licensed by Transport for London can carry out those trips.
"And when we send riders the booking confirmation we will let them know that TfL has licensed their driver, alongside information such as their name, photo, private hire licence number and car registration."
The changes come after TfL raised concerns some Uber drivers - particularly those operating at airports on the outskirts of London - may be licensed by neighbouring authorities.
It comes after the ride-hailing app recently pledged to report crimes directly to police, following concerns that passengers were being put at risk because of delays in the reporting of sexual assaults.
