Without publicly available data, it is challenging for me to determine the precise number of deliveries Uber Eats completes each day. However, given its presence in more than 500 cities worldwide, the figures could likely reach several hundreds of thousands or even millions. It's also important to recognize that these numbers may fluctuate due to factors like the day of the week, seasonal changes, and current market trends in the food delivery sector. I believe that Uber Eats handles a considerable amount of orders daily, especially considering its extensive reach and popularity among food delivery services.
