The Blues pair were part of manager Roy Hodgson’s provisional 26-man party ahead of the international tournament in France.
Centre-half Stones was already a certainty to travel with the Three Lions, but midfield playmaker Barkley was left sweating over his inclusion.
However, the 22-year-old was handed a place in Hodgson’s squad at the expense of Leicester City’s Danny Drinkwater and Newcastle United’s Andros Townsend.

The Toffees duo join Merseyside rivals Liverpool players Jordan Henderson, Nathaniel Clyne, James Milner, Daniel Sturridge and Adam Lallana in being named in Hodgson’s squad for Euro 2016, while former Everton starlet Wayne Rooney is also included.
Stones, 22, has acquired nine caps for England since making his senior national side debut in a 3-0 friendly win over Peru in May 2014.
Barkley, meanwhile, has 21 caps and two goals for the Three Lions after he was handed his first-team debut in a 4-0 World Cup qualifier against Moldova in September 2013.
England will face Russia in their opening Group B match at 8pm BST on Saturday June 11th, before a Battle of Britain clash with Wales at 2pm BST on Thursday June 16th.
The Three Lions will then take on Slovakia in their final group match at 8pm BST on Monday June 20th.
