On Tuesday afternoon Gareth Southgate announced his expanded squad, which will be trimmed down to 26 by the 1 June deadline.
And despite scoring 17 goals in the Premier League - making him the second-highest scoring Englishman - Bamford has been overlooked.
Instead, Dominic Calvert-Lewin, Ollie Watkins and Mason Greenwood have all been selected ahead of the Leeds United striker.
In the last international break, Southgate said Bamford was "very close" to earning a call-up but ultimately opted for Watkins, who scored on his England debut.
And after the Euro 2020 snub, plenty are calling for Bamford to commit his international future to the Republic of Ireland.
Eligible to play for Ireland through a grandparent, Bamford was capped once at Under 18 level in 2010 before going on to represent England at Under 18's Under 19's and Under 21's.
Previous Ireland managers Martin O'Neill and Mick McCarthy tried to convince him to play for Ireland but Bamford was always set on playing for his birth country.
"The idea of being selected for England is a dream," he told the Daily Mail in February.
"I thought about it before the last squad was announced and I didn't sleep properly the night before because I was wondering whether it was going to happen or not.
"I'm probably a bit down the pecking order but I just have to keep doing my thing. If I got one England cap in the whole of my career, I'd be over the moon."
Bamford is eligible to play for Ireland and would need to write to FIFA, proving that he does have an Irish passport to achieve the change.
Recently, Manchester City defender Aymeric Laporte was successful in changing international allegiance from France to Spain and was named in Luis Enrique's Euros squad.
