Trippier was a mainstay under Southgate and started England’s first six matches at Euro 2024 but was dropped for the final in favour of Luke Shaw.
He also started the Euro 2020 final defeat by Italy, and featured as a regular starter at the 2018 World Cup in Russia.
England interim coach Lee Carsley names his first squad at 14:00 BST for Nations League matches against the Republic of Ireland and Finland in September.
“Thank you to all my team-mates – we have had some very special moments reaching two Euro finals, and a World Cup semi final and I am sure in the future this group of players will win a major tournament,” he added.
“I want to wish Lee, the coaching staff and the team all the best for the future.
“And finally a big thank you to all the England fans for your incredible support travelling all over the world to support us and keeping us going in the difficult moments.”
