Additionally from FunkyMonk's answer, you may also want to put some checking to see if supplied name doesn't exist in %numbers to avoid unitialized warning.

print "Who's number are you looking for? : \n";
chomp(my $who = <STDIN>);
my $number = $numbers{$who} || 'unknown';
print "$who number is $number\n";
