Are you referring to your Square Cash or Register account?

For Square Cash, see this article: https://squareup.com/help/us/en/article/5187-about-square-cash#upgrade-to-cash-for-business

For Square Register, you'll need to talk with someone on our team (since this is an account-specific issue): https://squareup.com/help/us/en/contact

Hope that helps!
