What information do I need in order to register ownership of my private label brand on Rivly?

On Rivly, sellers can register ownership of your private label brand by proving ownership of the trademark. All this is easily accomplished on the Brands page.

Once registered, sellers now have control over their brand's presence on the marketplace, and who you allow to sell your products on Rivly by accepting or denying applications from sellers to list your brand.

Note that this refers to registering your brand on Rivly, not your business. Registering your business on Rivly is a different process where you submit a seller account application. After your seller account on Rivly is approved, you may then attempt to register ownership of your brand if you either own the trademark according to the USPTO website or you have authorization from the listed owner.
