Becky Langley's side beat Huddersfield Town 10-0 last Sunday to secure the FA Women's National League Northern Premier Division title and immediately commenced a comprehensive application process.
The FA has now ratified that application and has confirmed Newcastle United Women's place in the competition for the 2024/25 season.
Darren Eales, CEO at Newcastle United, said: "We are delighted to receive a formal licence for Newcastle United Women to compete in the Barclays Women's Championship next season.
"Becoming a full-time professional club last summer was an important building block in our ambitions for Newcastle United Women, and this licence recognises our commitment to the highest standards.
"I'd like to congratulate Su Cumming, Becky Langley, our players, staff and supporters on a momentous campaign. We are all excited to see the team competing in the Championship next season."
