No USPS Shipping Method

It’s hard to tell without the exact details about plugin settings, order, and what USPS returned for the request. Could you gather the debug info:
1. Enable the WooCommerce shipping debug mode: WooCommerce -> Settings -> Shipping -> Shipping options -> Enable debug mode.
2. Go to the cart/checkout page with the order you are getting unexpected shipping options for.
3. Look for the ‘Found X USPS rates’ notice on the top of the page and click ‘Copy’ there.
4. Paste the copied details here.
5. Disable the debug mode.

Hi, I am facing the same issue which is mentioned above.
This is what I am getting in debug mode.

Hi @promact,

Thank you for posting the debug details.

The issue is related to the origin postcode in the plugin settings set to ‘07103-3726’. It doesn’t look like a valid US zip code. What kind of postcode is it?

Hello @showrovsms,

'destination' => 
    array (
      'country' => 'UM',
      'state' => 'CA',
      'postcode' => '32503',
      'city' => 'dhaka',
      'address' => 'mohammadpur',
      'address_1' => 'mohammadpur',
      'address_2' => '2/2-B',
    ),

The selected country’s code is UM, which corresponds to the United States Minor Outlying Islands. Not sure if the outlying islands are considered for USPS domestic shipping.

The code of state selected is CA, California.

The zip code is 32503, Florida.

So, the address is incorrect. It seems that is the issue.

@mybestpaintingsource The issue is that mybestpaintingsource is not a valid USPS API ID. You would have to register another ID for USPS API. Or, just leave the User ID field empty.

Thank you Dan, that solves it! And thanks for the plugin!

Hello @subsomatic1, the error is
The Destination ZIP Code you have entered is invalid.

This issue that I’m having is that the shipping method isn’t showing up when I’m setting the methods in a specific shipping zone. I can’t imagine that a destination ZIP on the front end would be causing that error?

@subsomatic1,

The plugin doesn’t support shipping zones at the moment.

The ‘The Destination ZIP Code you have entered is invalid’ error is definitely caused by the incorrect zip code provided on checkout. The USPS API can’t provide a shipping price for an unknown destination.
