This covers adding any business, organization, or legal entity — including a trust — to your existing account. In each case, you will need to re-notarize USPS Form 1583.
1) Go to Settings
2) Press "Add a business"
3) Fill in info about the business or organization. If you're adding a trust, enter it here the same way — see Do I need to include my trust on my 1583 even though it isn't a business? for how to fill out the form fields for a trust specifically.
4) Complete USPS Form 1583. Keep in mind, you cannot use an address ID with your SavvyNomad address for the purpose of completing a 1583. You can use any other address in the entire world.
