  private static function generateNumber()
    {
        $number = Str::random(9);
        if (self::where('number', $number)->count() > 0) self::generateNumber();
        return $number;
    }

You can use Laravel's built-in helper method str_random which generate a more truly "random" alpha-numeric string as:

str_random(6)

The str_random function generates a random string of the specified length. This function uses PHP's random_bytes function.

So your final code will be as:

$voucher->code = str_random(6);

I am using this function You may use it like something like bellow

 $voucher->code = $this->generateRandomString(6);// it should be dynamic and unique 

public  function generateRandomString($length = 20) {
        $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
        $charactersLength = strlen($characters);
        $randomString = '';
        for ($i = 0; $i < $length; $i++) {
            $randomString .= $characters[rand(0, $charactersLength - 1)];
        }
        return $randomString;
    }

Here is this code

$chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$code = "";
for ($i = 0; $i < 6; $i++) {
    $code .= $chars[mt_rand(0, strlen($chars)-1)];
}

Replace your this line in your code with 

$voucher->code = $code;// it should be dynamic and unique

I hope this will work

EDIT

You can try other ways too

$code = strtoupper(uniqid()); // if you dont have any restriction on length of code

For length constraint try this

function generateCouponCode($length = 6) {
  $chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  $ret = '';
  for($i = 0; $i < $length; ++$i) {
    $random = str_shuffle($chars);
    $ret .= $random[0];
  }
  return $ret;
}
