Magento2.4: How to get Region name by Zip code?

I need to get the region name based on ZIP/Postal code. My code is below but its not working. Can anyone please help to get the region name by zip code?

$postcode = "560100";
$regionCollection = $this->regionCollectionFactory->create();
$regionCollection->addRegionCodeFilter($postcode)->setPageSize(1);

if ($regionCollection->getSize()) {
    $region = $regionCollection->getFirstItem();
}

Thanks in Advance!
