I don't understand why you're not using the regex that does away with
all that code.

$canadian_regex =
"/([A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})[A-CEG-HJ-NPR-TVXY]{1}
{1}([0-9]{1}[A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})/";
$zip = "A2B 3X4";

IF (preg_match($canadian_regex,$zip)) {
echo "Zip is Canadian\n";
} else {
echo "Zip is not Canadian\n";
}

--------
or
--------


$usa_regex = "/[0-9]{5}(-{0,1}[0-9]{4}){0,1}/";
$canadian_regex =
"/([A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})[A-CEG-HJ-NPR-TVXY]{1}
{1}([0-9]{1}[A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})/";

....

$isUSA = (preg_match($usa_regex,$zip)) ? TRUE : FALSE;
$isCanadian = (preg_match($canadian_regex,$zip)) ? TRUE : FALSE;


--------
or
--------

// by country ISO

$postal_code['US'] = "/[0-9]{5}(-{0,1}[0-9]{4}){0,1}/";
$postal_code['CA'] =
"/([A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})[A-CEG-HJ-NPR-TVXY]{1}
{1}([0-9]{1}[A-CEG-HJ-NPR-TVXY]{1}[0-9]{1})/";
$postal_code['VI'] = "/008[0-5]{1}1/";

$isUSA = (preg_match($postal_code['US'],$zip)) ? TRUE : FALSE;
$isCanadian = (preg_match($postal_code['CA'],$zip)) ? TRUE : FALSE;
$isVirginIslands = (preg_match($postal_code['VI'],$zip)) ? TRUE : FALSE;

etc.
