Answer 1

Use \Magento\Ui\Component\MassAction\Filter class for massDelete

protected $zipcodeFactory;

public function __construct(
    \Magento\Ui\Component\MassAction\Filter $filter,
    \Vendor\Module\Model\ResourceModel\Class\zipcodeFactory $zipcodeFactory,
    \Magento\Backend\App\Action\Context $context
) {
    $this->filter            = $filter;
    $this->zipcodeFactory = $zipcodeFactory;
    parent::__construct($context);
}

public function execute()
{
    try {
        $logCollection = $this->filter->getCollection($this->zipcodeFactory->create());

        foreach ($logCollection as $item) {
            $item->delete();
        }

        echo "Items Deleted"; exit;

    } catch (\Exception $e) {
        $this->messageManager->addError($e->getMessage());
    }
}

If you want avoid do a foreach, you can use a collection walk.

$modelcollection->walk('delete');
