In 2011, the then-Birmingham City goalkeeper said that he was no longer available for England duty because of ongoing injury problems.
But it is understood Foster has had a change of heart and is in contention to return for next month's World Cup qualifiers in San Marino and Montenegro.
The former Manchester United player, who won the last of his five caps three years ago, would provide competition for Roy Hodgson's current No.1, Joe Hart.
If he does return, Foster will be reunited with goalkeeping coach Dave Watson, who he worked with during his spell at Birmingham.
Foster has been in impressive form for West Brom after signing a new five-year contract in the summer.
