Opening a shop on Etsy is quite simple if you follow the correct steps, first, register with a valid email address like Gmail and look for the sell on Etsy button to start setting up your shop, there, you'll choose your shop name, which should be short and without spaces, and then define your currency and country.
For payments, Etsy will ask for your bank information or a verified paypal account, you'll also need to upload a photo of your ID and make sure the details match your bank account information exactly, because any discrepancies will result in your application being rejected. If you're in a country where SMS verification isn't available, you can use a virtual phone number from another country, don't upload too many products as soon as you open your shop, start with one or two high quality items, with good photos from various angles, there are listing fees and a commission per sale, so keep that in mind when setting your prices, if you want to be found more easily, learn the basics of SEO to put the right keywords in your titles and descriptions.
