Think of this pattern as a string of digits followed by any number of a sub-patterns consisting of a separator and more digits. 
use strict;
use warnings;
use feature 'state';
use Test::More tests => 2;

my @scenarios = (
  #     String                                  Expected match
  ["Link:1625 housing Link:2004",      ['1625',        '2004'      ]],
  ["Link:638 92-5000|Link:63892-5070", ['638 92-5000', '63892-5070']],
);

my $pattern = qr/\d+ (?: [- ]\d+ )* /x;
    
foreach my $scenario (@scenarios) {
    state $i = 1;
    my $str = $scenario->[0];
    my @matches = $str =~ m/Link: ($pattern)/gx;
    is_deeply( \@matches, $scenario->[1], "Scenario $i");
    $i++;
}
