Walcott became the youngest England international in history when he made his debut against Hungary in a pre-World Cup friendly in May 2006.
And after turning 19-years-old on Sunday, Walcott has expressed his joy at being named in Fabio Capello's 30-man squad.
"I celebrated my 19th birthday on Sunday," he told the club's official website.
"So the call-up is a great birthday present for me. I'm looking forward to meeting up with all of the lads after the weekend's game."
