I have made a zone and rate where I included every single country. When I go on to my online store from my phone and try to order a product, the only “country/region” option I get is the USA. I really want to offer worldwide shipping on my website. Can someone help me? 
Hi, @storm30687 .
Can you confirm if you’re seeing something like the below on your checkout page?
If you’ve ensured that you have shipping rates set up for your international destinations, you can head over to Settings > Markets on your Shopify admin to check if those same countries have also been activated as a market. If you see a market that hasn’t yet been activated, you can click Manage > Activate as seen below. This will then allow the countries to appear within the dropdown option on your store’s checkout. More information on this can be found on this help guide.
If a region you’d like to ship to hasn’t been added as a market at all however, you can simply click on the Add market button instead to create a new market specifically for that region.
Once the correct markets have been set up for your international shipping destinations, you can test your checkout again to see if the countries and regions will now show up within the dropdown list. Remember that you can also fully test your checkout by putting your payment provider on test mode, to make sure that the checkout process is operating smoothly and as intended. We have instructions here that you can check, if you need guidance on how to place a test order on your store. If you’re using Shopify Payments, follow the instructions listed here instead.
