DoorDash delivers essentially 24/7, but how late delivery is available depends mainly on the operating hours of restaurants in the area. In most cities, DoorDash delivers until around 11 PM to midnight, but in major metropolitan areas like New York, Los Angeles, Chicago, and Houston, DoorDash can operate practically 24/7 or until the early morning hours (1-3 AM). In smaller towns or cities, restaurants typically close earlier, often by 10 or 11 PM, which stops the availability of DoorDash orders since restaurants need to be open for the service to work. The DoorDash app itself is always available, but if no restaurants are open or no drivers are available, ordering won't be possible at those times.
So, DoorDash delivery hours are tied to restaurant hours in the area, and while DoorDash as a platform is 24/7, delivery availability late at night varies by location and day of the week.
