Answer

You need to compare string with string if the leading 0 of the zipcode is important:

$zipcode1 = "07300-011";
$zipcode= str_replace("-","",$zipcode1);
$zipcode = "07300011";
if ($zipcode >= "20000000" && $zipcode <= "26600999") { 
    echo '1';
} elseif ($zipcode >= "07000001" && $zipcode <= "07399999") { 
    echo '2';
} else {
    echo 'no value';
}
