I didn’t establish my business yet. Can I verify my business account anyway?
In case you don't have an established business, instead of a business registration certificate, you can upload a document which proves that you are paying taxes from your activities as a sole trader. You also need to provide the most recent tax declaration, which preferably should include income from your sole proprietorship.
Lastly, please select a “Sole Trader” status when filling out the verification form.
