I'm develop a module for shipping method. I need order's address to calculate freight.

use Magento\Quote\Model\Quote\Address\RateRequest;

$destCountryId = $request->getDestCountryId();
$destState = $request->getDestRegionCode();
$destCity = $request->getDestCity();

If customer not login ,they need to input address like picture enter image description here I can use my code to get address. But if customer have logined and select address. enter image description here My code can get country and city ,but can't get State with getDestRegionCode(). What's wrong with my code.Or may be someone can tell me how to get address is right.


In your Model Carrier, add the following code after "$destPostcode = $request->getDestPostcode();"

if ($request->getDestRegionId()) {
        $regionCollection = $this->_regionCollectionFactory->create();
        $regionCollection->addFilter('main_table.region_id', $request->getDestRegionId());
        $region = $regionCollection->getFirstItem();

$destRegionCode = $request->getDestRegionCode();

You will also need to add the regionCollecttionFactory to your Constructor:

\Magento\Directory\Model\ResourceModel\Region\CollectionFactory $regionCollectionFactory

  • thanks,and what's function _getQuotes(),i create it before your answer. – keke996 Apr 20 at 7:23
  • _getQuotes() is the function that will call the API to retrieve the shipping rates, You probably gave a different name to it. – Andresa Martins Apr 20 at 7:25
  • sorry , I can't find _getQuotes() function in my code,I just $result->append($method) and return in collectRates(). now I add your setRequest() into my code and $this->setRequest($request) in collectRates(), now my page is worng .can't find _countryFactory – keke996 Apr 20 at 7:38
