Can I use the service if I already have a Y-tunnus (Business ID)?

Yes, you can! If you already have a Y-tunnus, you can still easily sign up for the Truster sole trader (toiminimi) service by following our instructions. Setting up the service doesn't require closing down your existing company — instead, we'll help you smoothly transition into using the sole trader service. After you place your order, we'll keep you updated on the transfer process so you can focus on your business without worrying about administrative details.
