Sunderland will begin their Carabao Cup campaign with a trip to League Two Port Vale in August.
The Black Cats will travel to Vale Park to take on Darrell Clarke's Valiants in the week beginning August 9.
It will be the first time the sides have met in this competition, although they have faced each other recently in both the EFL Trophy and the FA Cup.

The Black Cats won 2-0 at the Stadium of Light in January in the Northern Section third round of the EFL Trophy, en route Wembley before getting their hands on the silverware, with Aiden O'Brien and Aiden McGeady scoring the goals against Vale.
And they also met in the first round of the FA Cup in November 2018, with goals from George Honeyman and Lynden Gooch giving Sunderland a 2-1 victory at Vale Park.
The first round draw was made live on Sky Sports News this afternoon by former Sunderland and Newcastle striker Andy Cole, and ex-Middlesbrough defender Danny Mills.
Sunderland fell at the first hurdle in the Carabao Cup last season, losing out to eventual League One champions Hull City on penalties at the Stadium of Light after the tie had ended goalless.
