Aria here, I'm on the Social Care team at Shopify.
Which country is your business based in? You can find a full list of payment gateways by country in this guide. It's important you select a payment gateway from the list that is available for your own country to avoid disruption in service. If you're not located in the US, you can't use a US payment gateway.
Stripe is not available in the US, it's Shopify Payments which is powered by Stripe but a different gateway.
You need to choose a payment gateway specific to the country you're physically located in. If you set up Shopify Payments with a US address but you're always logging in from Croatia, they will end up putting your Shopify Payments account on hold and potentially cancelling it, which can disrupt your business. This is because of the agreement Shopify has with our banking partners.
When you're setting up Shopify Payments from the US, you need an EIN (Employee Identification Number) and US-based bank details.
