When signing up as a merchant on Universe, you are prompted to sign up as an Individual or a Business.
If you initially sign up as an Individual but need to change your account to a Business type, simply contact our support team and let them know. They'll ask you for some information (including an EIN*) and will be able to update your account so that it is linked to your business.
*An Employer Identification Number (EIN) is also known as a Federal Tax Identification Number. This number is universally used to identify a business entity with the government. Businesses generally need an EIN to legally operate and sell. To sell as a business on Universe, you are required to provide your EIN as well as other measures of verification to receive your payouts from items sold.
