Is the ZIP code always at the beginning of the filename? You can use the core module File::Basename to strip off the path:

use warnings;
use strict;
use File::Basename qw/fileparse/;

my @files = ( '-/yf/-/22211_01_09_2000_XYz.pdf',
    '_/gt/-/02239_04_04_1989_PkW.pdf',
    '-/xy/-/02239_04_04_1989_PkW.pdf' );

for my $file (@files) {
    my $bn = fileparse($file);
    my ($zip) = $bn =~ /^(\d{5})\D/;
    print "$file => $zip\n";
}
